Lacha mhuinceach
Status: A rare winter visitor to wetlands from October to March, almost always associating with flocks of Tufted Duck.
Conservation Concern: Green-listed in Ireland. The European population is regarded as Secure.
Identification: Very similar to Tufted Duck and care is needed to distinguish the two species. Slightly smaller than Tufted Duck and lacks that species distinctive crest. Adult males can be separated from Tufted Duck by having much greyer flanks with a white vertical stripe, as well as different pattern on the bill (broad white stripe near the tip). Adult females appear quite different to female Tufted Duck, being much paler overall and having an obvious white eyering. Also shows a hint of the obvious vertical white stripe found on the flanks of the male. Juvenile Ring-necked Ducks are similar to females, though the head pattern is not as contrasting and lacks the broad white stripe on the bill.
Similar Species: Tufted Duck
Call: Generally silent when seen in Ireland.
Diet: Mainly feeds by diving for freshwater invertebrates (beetles, shrimp). Ring-necked Ducks will also feed on plants, such as pondweeds.
Breeding: Ring-necked Ducks breed in central and northern North America.
Wintering: The species winters south of the breeding grounds in the United States to Central America. Occasionally wanders to Ireland and then can be seen with Tufted Duck on larger lakes. In September/October 2008, a flock of 15 was recorded on Inishmore on the Aran Islands.
Where to See: Ring-necked Ducks could be seen in any large flock of Tufted Ducks in Ireland.

Status: Resident along rocky coasts in the north and north-west of Ireland.
Conservation Concern: Amber-listed in Ireland due to the majority of Eiders wintering at less than ten sites.The European population is regarded as Secure.
Identification: Large and heavy-built, with short neck, large head, long wedge-shaped bill. Birds seen in irregular - loose clusters. Males largely white with black belly, sides and stern. Head white with black crown, and pale green on sides of the nape.
Similar Species: Adult male is unmistakable. Females and immature resemble other duck species.
Call: Male with cooing display-call, and a far carrying 'a-ooh-e'.
Diet: They generally feed by diving in waters up to 20 m depth, feeding predominantly on mussels, other molluscs, crustaceans and echinoderms.
Breeding: Eider nest colonially on offshore islets, along low-lying coast, usually where the threat of mammalian predation is minimal. Eider seldom occur far from the sea throughout the year. They breed around the coast of Scotland and northern England and along the north and northwest coasts of Ireland. Up to 100 pairs have been estimated in Ireland.
Wintering: Occurs on shallow, inshore coastal waters, near estuary mouths mostly along the northwest and northeast coastlines.
Where to See: Belfast Lough in County Down and Outer Ards in County Down regularly supports almost 1,000 & 500 birds respectively. Lough Foyle in County Derry, Strangford Lough in County Down, Larne Lough in County Antrim and the Streedagh Estuary in County Sligo and other well-used wintering sites on the east coast, including estuaries and inlets between Dundalk and Skerries in north Dublin.
Physical characteristics
The Common Eider Somateria mollissima is the largest duck in the northern hemisphere. It weighs an average of 1 800 g, but its weight can vary from 850 to 3 025 g depending on race, sex, and time of year. There are four Common Eider races in North America; subtle differences in body size and bill structure distinguish each race from the other.
The plumage of the Common Eider varies considerably. It passes through several stages while the bird is growing to maturity, and after the bird reaches adulthood at about three years old, the plumage alternates between two colours each year as a result of moulting, or the replacement of old feathers with new. In addition, the male's plumage differs from the female's.
Between the ages of three weeks and three years, male Common Eiders moult their feathers eight times, changing their colour from a juvenile blackish brown to an adult olive-brown and white in winter and a striking black and white, with a small area of light emerald green on the back and sides of the head, during the breeding season. Changes in female plumage are less dramatic: from a juvenile blackish brown, the duck becomes rusty-to-tan. The female's summer colours provide good camouflage in the vegetation and rocks of the offshore islands on which she breeds.
Common Eiders can live 20 years, one of the longest lifespans among sea ducks. However, the expected lifespan for eider populations which are heavily harvested may be much shorter.
Habitat
Of all sea ducks, the Common Eider is the most closely tied to marine habitat. It lives in arctic and subarctic coastal marine areas, where it frequents coastal headlands, offshore islands, skerries, and shoals. The Common Eider rarely leaves the water in the winter, and some races remain as far north as there is open water. The seven races of Common Eiders have different breeding ranges. In North America the southern race Somateria mollissima dresseri breeds from Maine to Hamilton Inlet on the Labrador coast; the northern race Somateria mollissima borealis breeds from northern Labrador to Ellesmere Island in the eastern Canadian Arctic; the Hudson Bay race Somateria mollissima sedentaria remains all year within Hudson Bay; and the Pacific race Somateria mollissima v-nigra breeds from Coronation Gulf in the MacKenzie District of the Northwest Territories to the south side of the Alaskan peninsula. Three subspecies are found outside North America: one in northwest Europe, one in Iceland and a third in the Faeroe Islands north of Great Britain.
The Common Eider belongs to the sea duck tribe (Mergini), which contains closely related ducks, all of which use marine habitats to some degree. The King Eider Somateria spectabilis, Spectacled Eider Somateria fischeri, and Common Eider all belong to the same genus, and hybridization is known to occur between Common and King Eiders. Eider ducks are gregarious, travelling and feeding in flocks numbering from tens to thousands.
Other details
This mainly marine species is breeding on arctic islands, in the north-west and extreme east of Eurasia and in North America. Some populations are sedentary. Others are migratory, wintering mainly in Denmark, northern Germany and the Netherlands, but reaching the Atlantic coasts of France. A few birds are seen in Central Europe and the western Mediterranean. The population of north-western Europe is totalling 1.7 to 2.3 millions of individuals (Scott & Rose). A few birds also reach Greece. They probably belong to a small population inhabiting the Ukrainian shores of the Black Sea
Teal,
Order ;- Anseriformes,
Family ;- Anatidae,
Species ;- Anas crecca,
The smallest common surface-feeding duck, the Teal is agile and quick in flight, its movements recalling those of a wader, Nervous groups may often swoop down to a sheltered bay, only to dart over the water surface and wheel up and away once more, sometimes several such approaches precede their eventual settling,
In places, Teal occur in hundreds but 20 - 40 are more typical, scattered along well-vegetated or muddy shores, or in wet marshes,
Breeds in N and E Europe on freshwater marshes and wet moor and heaths, including high moorland pools, Winters more widely in S and W Europe, mostly on fresh waters with muddy edges and around estuaries, An absence of bright colours on the bill and legs helps to identify the female Teal,
Voice ;- Male has lod, ringing, high-pitched ' cirk crik ' that can be easily heard at long range marshes or estuaeies, female has high quack,
Nesting ;- Down-lined hollow near water, 8 - 11 eggs 1 brood, April - June,
Feeding ;- Mosly in water or on muddy shores, taking plants and seeds,
Length ;- 34 - 38 cm ( 13.5 - 15 in ),
Wingspan ;- 58 - 64 cm ( 23 - 25 in ), Weight,- 250 - 400 g ( 9 - 14 oz ).
Social ;- Small flocks,
Lifespan ;- 10 - 15 years,

Songs and Calls
Low rasping croaks.
Status: Resident at larger lakes in Counties Wicklow and Donegal. Rare winter visitor throughout Ireland.
Conservation Concern: Amber-listed in Ireland, due to its small breeding population. The European population has been assessed as Secure.
Identification: Large, long-bodied, with a long narrow red bill ending in a hook. Swimming birds often retract their long necks. Adult males largely white with glossy green-black neck and head. Back largely black. Females with dark red-brown head, though with a white throat patch, greyish body.
Similar Species: Red-breasted Merganser.
Call: Male call is deep muffled 'krroo-krraa'.
Diet: Goosanders feed largely on small and medium sized fish, and occasionally larger fish such as Pike.
Breeding: Breed on freshwater lakes and pools and winter on large unfrozen lakes and brackish lagoons and occasionally on coastal estuaries. The most recent breeding records in Ireland come from County Wicklow, where one pair was confirmed breeding in 1994, and annual breeding has since been deemed likely, though not confirmed.
Wintering: Irish birds appear to be largely resident. Birds from Continental Europe can occasionally found along coastal areas in winter.
Where to See: Found on freshwater. Belfast Lough in County Down and Lough Tay & Dan in County Wicklow are the most regularly used wintering areas.
Physical characteristics
The long, narrow bill with serrated edges readily distinguishes mergansers from all other ducks. Common mergansers are among the largest ducks, but are less stocky than eiders and goldeneyes. In flight, they appear more elongated than other ducks, flying in trailing lines close to the water surface.
Male common mergansers have a greenish-black crested head and upper neck. The lower neck, breast, and underparts are creamy-white with a variable pink wash. They have black backs and upperwing coverts with white scapulars. The bill is red with a blackish culmen and nail. The legs and feet are deep red.
Female common mergansers have a tufted red-brown head that is clearly defined from the lower neck by a clear whitish chin. The back and sides are silver-gray and the breast and belly are white. The bill is red with a blackish culmen and nail. The legs and feet are deep red.
Habitat
Common mergansers nest in tree cavities, nest boxes, cliff crevices, and on the ground generally near clear water rivers in forested regions and mountainous terrain. They feed by diving underwater in marine and freshwater habitats.
Other details
This duck has a wide distribution in boreal and temperate regions of Eurasia and North America. It has also isolated populations in the mountainous regions of the Alps, the Caucasus and Tibet. Two populations inhabit or visit the European Union. One comprises the birds of northern and north-western Europe, wintering mainly in the Baltic Sea and around the North Sea. It amounts to about 200000 individuals, and seems stable. The birds of the British Isles are sedentary. They amount to about 5000-8000 individuals and increased during the last decades. The population of Central Europe (France, Germany) amounts to 3000 individuals. It is also sedentary and seems to be slightly increasing. A very small population is breeding in the Balkan Peninsula. It is estimated at not more than 11-32 breeding pairs, and its trends are unknown
Feeding
Common mergansers eat mainly fishes, amphibians, crustaceans, mollusks, and other invertebrates obtained by diving underwater in marine and freshwater habitats
Conservation
This species has a large range, with an estimated global Extent of Occurrence of 10,000,000 km². It has a large global population estimated to be 450,000-1,400,000 individuals (Wetlands International 2002). Global population trends have not been quantified, but the species is not believed to approach the thresholds for the population decline criterion of the IUCN Red List (i.e. declining more than 30% in ten years or three generations). For these reasons, the species is evaluated as Least Concern. [conservation status from birdlife.org]
Breeding
Common mergansers breed from Alaska, the southern Yukon, Labrador, and Newfoundland south to central California, Arizona, New Mexico, southern Chihuahua, and, east of the Rockies, to Minnesota, Michigan, New York, New England, and Nova Scotia. Common mergansers nest in tree cavities, nest boxes, cliff crevices, and on the ground generally near clear water rivers in forested regions and mountainous terrain. Female common mergansers lay an average of 9 to 12 eggs.
Migration
Migratory and partially migratory. No evidence that any Icelandic breeders emigrate. Similarly, British breeders almost entirely resident, moving short distances (mainly within 150 km) from breeding waters to lakes and sheltered estuaries. No evidence that breeders of southernmost Scandinavia, north Germany, and Poland move further than western Baltic, but those breeding central and northern Scandinavia, Finland, Baltic States, and Russia east to Pechora migrate west to Baltic and beyond to Netherlands and Britain, in smaller numbers to west France and north Spain. In late August and early September, moulting and breeding waters often deserted as flocks build up on estuaries and shallow parts of some inland lakes. Mass departures not until advent of freezing; thus major movements through Russia and Baltic October and early November. Early arrivals in North Sea countries late October and early November, but no large numbers until December, while numbers build up on Black Sea and Sea of Azov from mid-October to mid-December. Return migration from early March and, apart from stragglers, non-breeding range vacated by mid-April.

Brent Goose (Dark-bellied)
Branta bernicla bernicla
Status
A rare winter visitor from Siberia from October to March.
Identification
Very similar to the much commoner Light-bellied Brent Goose and care is needed to separate the two species. Dark-bellied Brent can identified by the darker and much more extensive grey colouring on the flanks and back. The white flank patch that is very obvious in Light-bellied Brent Goose is reduced to a stripe along the flanks. Juvenile Light-bellied Brent similarly show a lack of a white flank patch, however these have extensive white barring on the back, which is not shown by adults.
Voice
Indistinguishable from Light-bellied Brent Goose.
Diet
Favoured food is eel-grass found in coastal estuaries. Dark-bellied Brent Geese also feed on other estuarine plants such as glassworts and sea aster, and to a lesser extent grasses and cereals
Breeding
Dark-bellied Brent Geese breed in the tundra of northern Siberia
Wintering
The majority of Dark-bellied Brent Geese winter in the Netherlands, northern France and the United Kingdom. This sub-species is a rare winter visitor in Ireland, where it associates with Light-bellied Brent Geese at coastal sites (mainly estuaries)
-------------------------------------------
Light-bellied Brent Goose
Branta bernicla hrota
Cadhan
This population winters almost entirely in Ireland, with small numbers in parts of Britain and France.
Status: Winter migrant from high-Arctic Canada. Most occur in Ireland between October and April.
Conservation Concern: Amber-listed as the majority winter at less than ten sites. The Irish population is also internationally significant, another amber listing criterion. The European population has been evaluated as Vulnerable as several important populations declined.
Identification: Small dark goose, with a black head, neck and breast, and dark-brown upperparts and pale underparts. Almost whitish flanks, and small white crescent on the upperparts of the neck visible at close range.
Similar Species: Dark-bellied Brent Goose, Black Brant, Barnacle Goose
Call: Gutteral 'rhut, rhut'
Diet: During the winter, it feeds mostly on eel-grass, which grows on muddy estuaries, and also on grasslands, usually when coastal supplies have been depleted at estuarine sites.
Breeding: Nests in small, loose colonies by coastal tundra, with pools and small inlets.
Wintering: Mostly found on coastal estuaries during the autumn and early winter, and also on grasslands from mid-winter, until departure for the breeding grounds begins in late April.
Where to See: Highest numbers (c. 30,000) are seen at Strangford Lough in Northern Ireland in October, where most congregate on arrival. Thereafter, they move to other estuarine sites. Lough Foyle in County Derry, Dublin Bay in County Dublin, Tralee Bay, Lough Gill & Akeragh Lough in County Kerry, Rogerstown Estuary in County Dublin, Wexford Harbour & Slobs in County Wexford are other well-used sites (1,000-3,500 birds).
Physical characteristics
The Brant is similar in appearance to the Canada Goose, but smaller and darker. The adult has a gray belly and breast, white rump, and black neck and head with a thin white necklace and no chin-strap.
Fast fliers with swept-back wings, Brant are usually found in a flock. They forage while wading, dabbling in shallow water, or while walking on mudflats or the shore. They display strong site-fidelity to both their wintering and nesting areas.
Habitat
Brant are almost exclusively coastal in their range and are found in shallow bays and saltwater marshes. They nest in the wet, coastal tundra of the high Arctic. Their winter habitat is closely tied to the occurrence of sea grasses and marine algae.
Other details
Branta bernicla is a rare breeder in the European Arctic, but winters mainly in coastal areas of western Europe, which accounts for less than half of its global wintering range. Its European wintering population is large (>240,000 individuals), and increased between 1970-1990. Although a few populations increased or were broadly stable during 1990-2000, key wintering populations (of the subspecies B. b. bernicla) in the United Kingdom, France and the Netherlands declined, and the species underwent a large decline (>30%) overall.
This goose is breeding on the arctic coasts of Eurasia and North America, mainly on small islets protected from polar foxes (Alopex lagopus). It winters along the temperate Atlantic and Pacific coasts. The birds visiting the European Union belong to three different populations (Scott & Rose). The first population, estimated at 20000 individuals, comprises the white-bellied birds of the race hrota, breeding in Greenland and northern Canada and wintering in Ireland. The second population, estimated at 5000 individuals, comprises the birds of the race hrota breeding on Svalbard and wintering in Denmark and north-eastern England. The third population, estimated at 300000 individuals, comprises the dark-bellied birds of the nominate race, breeding along the Russian coasts and wintering in Denmark, Germany, the Netherlands, south-western England and France. All three populations have undergone important fluctuations. The nominate race has experienced a 90% decline during the 1930s following a disease of its foodplant, Zostera marina. It has started to recover since the 1950s, and the increase is still in progress. The populations of Canada and Greenland have increased since the 1960s and seem currently to be stable. The population of Svalbard dropped from about 40000-50000 to a mere 2000 at the end of the 1960s, not only because of the disease of Zostera but also because of non sustainable hunting. Since the 1970s it has recovered
Feeding
Historically, Brant fed almost exclusively on eelgrass, which is still strongly preferred when available. Now they also forage on grasslands and have been able to diversify their diet in the absence of eelgrass, although their range is still closely tied to eelgrass. Brant also eat some aquatic invertebrates.
Breeding
Long-term pair bonds usually form on the wintering grounds. Nesting occurs in loose colonies, on small islands in tundra ponds. The breeding range of the Brant is typically within five miles of the coast. The nest is a shallow bowl of grass and other vegetation, lined with down. The female incubates 3 to 5 eggs for 22 to 24 days. The young leave the nest within a day of hatching, and both parents continue to tend them and lead them to sources of food. During the long days of the high-Arctic summer, the young feed at all hours, and grow quickly. They fledge at 40 to 50 days, but stay with the parents through the first migration.
Migration
Single wholly migratory population. Depart Russian tundras mid-August to 1st week September. Main route west along arctic coasts to White Sea, then overland to Gulfs of Finland and Bothnia. Passage through Baltic mid-September to early October; first arrivals Denmark late September but bulk October. Some stay Denmark and western Germany through November before moving on in colder weather; others go straight to winter quarters in Netherlands, south-east England, and west France, where peak numbers December-February. Return passage begins early March; most leave England and France by mid-April. Spring gatherings in Netherlands, Denmark and western Germany until main departures in mid-May; only stragglers after mid-June.

The Freckled Ducks had gone foraging when I took this shot but it gives an idea of why the birds bunch up together. Real eastate is at a premium. This is the tip of the island and the whole thing is covered in birds.
Not only that there is a large group to the left of where I took this from and an even larger crowd of many species strung out along the right bank. Then there's all the flotillas out in the water. It's crowded! And the Cattle Egrets will start nesting in the next few months and arrive in thousands!

Order: Anseriformes
The Magpie Goose is the only extant member of the family Anseranatidae. Its breeding territories are now restricted to Northern Australia and New Guinea though it is sometimes seen further south when not breeding. In the past, it had a more extensive range but this was reduced due to human activity and the draining of their wetland territories.

"The paradise shelduck (Tadorna variegata) is a large goose-like duck endemic to New Zealand.. It is a shelduck, a group of large goose-like birds which are part of the bird family Anatidae. The genus name Tadorna comes from Celtic roots and means "pied waterfowl". Known to the Māori as pūtangitangi, but now commonly referred to as the "paradise duck", it is a prized game bird. Both the male and female have striking plumage: the male has a black head and barred black body, the female a white head with a chestnut body." - Wikipedia

Welcome to my Flickr 365 Project! I’m calling it my 365 Species Project, because for each day of the year, I will post a photo of a different species of organism... My goal was to accomplish all of this in 2013, but I soon found out that it was more daunting a task than I'd realized. Instead, my new goal is to get through 365 by the end of 2014, still an impressive average of a new species every other day for two years.
Today is New Year's Eve, and I'm so happy to be sharing the final photo with you! What can I say that will properly wrap-up this project that has been in my life for the past two years??? I'm so proud of the way it has turned out. There is still lots of room for improvement (a few of the photos are terrible), but the change I've seen since the beginning has been massive. I'm really proud of how much I've grown as a wildlife photographer, and I'm really proud of how much I've learned. This project has accomplished exactly what I hoped it would!
There are too many people to thank here. They've all put up with my requests for detours and long stops on my various trips. Included in this project are two trips to Africa, one trip to Belize, a trip to California and Oregon, and lots and lots of photos from all over Florida. Many people helped me on each and every one of these adventures. I'd like to thank all of my Flickr friends for views, comments, and favorites. Many of you have been so encouraging! So thank YOU!!!
I don't know what my next project will be, but I hope it will be as good as this one. I will continue shooting and posting, so I hope you all continue to watch my Photostream for the latest updates. If you haven't kept up with the Project, take a moment to look through a few of the highlights in the album. And if you're interested, I'm planning to randomly post some of the very best of the project to my (relatively new) Instagram account, @bsmity13.
HAPPY NEW YEAR TO ALL OF MY FLICKR FRIENDS!!! I hope 2015 will be even better than 2014 for all of us!!!
CHEERS!!!

There has been a decline in breeding numbers since the 1970s - 96 pairs were estimated in 1995 and 80 in 1999. Eutrophication of the waters has reduced the species’ food supply which has resulted in poor productivity and juvenile survival. Mink predation has also had a considerable impact during the breeding season, and incubating females have been most vulnerable. However, in recent decades, it has been suggested that birds may be redistributing to other large lakes in western and central Ireland.
Status: Resident and winter visitor from the Continentto all Irish coasts between October and April.
Conservation Concern: Red-listed due to its declining breeding population. The European population has been evaluated as Secure.
Identification: Medium-sized, plump duck usually seen in large flocks offshore. At closer range, males with yellow knob at base of bill. All dark plumage, with no white on the wing. Males black, females sooty brown with paler cheeks.
Similar Species: Velvet Scoter and other ducks.
Call: Soft piping 'pju'.
Diet: During the summer the diet is varied and includes water plants, insect larvae and freshwater crustaceans. During the winter, they forage mostly in waters less than 20 m deep and with coarse sandy substrates. They feed predominantly on benthic bivalve molluscs.
Breeding: First recorded breeding in Ireland in the beginning of the 20th century at Lower Lough Erne. Numbers increased steadily - up to 150 pairs were estimated during the late 1960s. They nest on islands with dense covering of scrub and tree cover. The breedding population has declined since due to the increase in Mink, which predate the nests and young.
Wintering: Common Scoter are almost entirely marine during the winter, and tend to congregate in large flocks on shallow seas with sandy bottoms supporting their preferred prey.
Where to See: Wexford Bay in County Wexford, Castlemaine Harbour & Rossbehy in County Kerry, Brandon Bay - Inner Brandon Bay in County Kerry, Donegal Bay in County Donegal and from Ben Head to Skerries on the east coast are among the best wintering sites, supporting 800-4,500 birds.
Physical characteristics
Black Scoters are large, mostly black or dark gray sea ducks. Formerly called the Common Scoter, the Black Scoter is the least common of the three scoters. Adult males are solid black with a bulbous yellow knob on an otherwise black bill. Females and juveniles are dark gray, lighter on the cheek with a dark cap. Their bills are dark and lack the knob found in adult males.
Scoters spend the non-breeding part of the year in large flocks on the ocean. Black Scoters forage by diving and swimming under water, propelled by their feet. They usually feed in areas of open water, avoiding dense submergent or emergent vegetation. They swallow their prey under water, unless it is large or bulky. They are strong fliers, but must get a running start on the water to get airborne.
Habitat
The breeding range of the Black Scoter is at the edge of the northern forest or in the treeless tundra, where they breed on small, shallow lakes, ponds, sloughs, and river banks with tall grasses to conceal nests. In winter, they can be found on coastal bays and along coastlines, usually in shallow water within a mile of shore.
Greylag Goose,
Order - Anseriformes, Family - Anatidae, Species, - Anser anser,
Of all grey geese, the Grey lag ( the direct ancestor of the domestic goose ) most resembles the farmyard goose.
It is also the most easily seen grey goose in the UK because it has been introduced in many lowland areas where sizeable flocks are now semi-tame and resident all year round.
Winter visitors are still wild and shy.
In much of eastern and central Europe, the Greylag is naturally resident in extensive marshes,

Anas strepera
Gadual
Status: Scarce resident at wetlands mainly in the south and east of Ireland.
Conservation Concern: Amber-listed due to its small breeding population, as well as the localised wintering population (less than ten sites). The European population of Gadwall has been assessed as Depleted, due to a large historical decline.
Identification: Large, but slightly smaller than Mallard. Small white speculum prominent in adult male. Males with brown head, black stern and grey body. Females similar to Mallard, though whitish belly, small white speculum, an orange, even stripe along the cutting edge of the bill.
Similar Species: Mallard and other duck species.
Call: Males with short, croaking 'ahrk' and high-pitched whistling 'pee' in courtship. Females with quacking call similar to Mallard.
Diet: They feed on a mixed diet of seeds, insects and aquatic vegetation.
Breeding: Nest on a variety of freshwater and brackish wetlands, especially shallow lakes with abundant emergent vegetation, slow moving rivers and marshes.
Wintering: Localised wintering distribution at a variety of inland and coastal sites.
Where to See: Loughs Neagh & Beg in County Antrim, Tacumshin Lake in County Wexford, Lady's Island Lake in County Wexford, Strangford Lough in County Down and the Corofin Wetlands in County Clare are among the top sites (each supporting 80- 150 birds).
Physical characteristics
Gadwalls are medium-sized ducks characterized by a general lack of bright coloration. Males are gray-brown, with a white belly, and a black rump. In flight, a white speculum and chestnut and black portions on the wing coverts are displayed. The bill is slate-gray and the legs and feet are yellow. The male utters a short "nheck" and a low whistle. Female gadwalls are similar to males, but have a mottled brown appearance, a yellowish bill with dark spots, and a smaller white speculum. She utters a repeated "gag-ag-ag-ag-ag" higher in pitch than the mallard.
Habitat
Female gadwall nest in fields and meadows, and on islands and dikes in wetlands. They are found in reservoirs, farm ponds, and coastal fresh and brackish marshes.
Other details
A species breeding in the temperate regions of North America and Eurasia. The breeding populations of the western parts of the European Union are more or less sedentary, but they are increased in winter by migratory birds from the Baltic region. This population is totalling 30000 individuals, and seems to have increased during the last decades (Scott & Rose). The birds breeding in Greece or visiting Greece in winter belong to a more oriental population, estimated at 75000-150000 individuals but currently declining
Feeding
Aquatic vegetation makes up the majority of the gadwall's diet. As a result, they are often found feeding far from the shoreline, in deeper water than most other dabbling ducks. Gadwall up-end to feed on leafy portions of pondweeds, naiad, widgeon grass, water milfoil, and algae and the seeds of pondweeds, smartweeds, bulrush, and spike rush. They also feed on aquatic invertebrates, such as crustaceans and midges.
Breeding
Gadwall breed near seasonal and semi-permanent wetlands, mainly in the shortgrass, tallgrass, and mixed prairie regions of the US and Canada. Substantial numbers also breed in wetland habitats of the Great Basin. Gadwall tend to begin breeding later than most ducks. Female gadwall nest in fields and meadows, and on islands and dikes in wetlands and lay an average of 7 to 12 eggs.
Migration
Partially migratory; northernmost breeding birds descend to lower latitudes in winter, but breeders of more temperate regions mostly sedentary.

Baer's pochard (Aythya baeri) is a diving duck found in eastern Asia. It is a resident bird in North and Central China, formerly bred in southeast Russia and Northeast China, migrating in winter to southern China, Vietnam, Japan, and India. Baer's pochard is a monotypic species. The holotype was collected in middle Amur.
It has a distinctive black head and neck with green gloss not present elsewhere in Aythya. While in poor light, it is likely to look completely black. It is very similar and closely related to the ferruginous duck, and they were previously considered to be a single species; Baer's pochard is differentiated by its white flanks when floating on the water, as well as its larger size and longer, more rounded head.
Its breeding season varies by latitude and environment. The nest, built from sedges, reeds and other plants, is placed among emergent vegetation, usually in shallow water or on small islands or ridges. Its clutch size ranges from 5 to 14. Males usually take on sentry duty, and females take on the responsibility of incubating.
Baer's pochard was once a common species in its range, but is now very rare. The number of mature individuals may be less than 1,000, and its population is still declining. Hunting and habitat loss are considered to be the main reasons. This species has been classified as critically endangered by the IUCN, and listed as a first-class protected animal in China.
Taxonomy
Baer's pochard was first scientifically described in 1863 as Anas baeri by Gustav Radde in his book Reisen im Süden von Ost-Sibirien. The epithet and English common name commemorate the Baltic German naturalist Karl Ernst von Baer. It is also called eastern white-eye, Siberian white-eye, Baer's white-eye and green-headed pochard. The holotype was collected from a small flock in middle Amur during the breeding season. In 1929, when British ornithologist E. C. Stuart Baker studied the birds of British India, he treated Baer's pochard and ferruginous duck as conspecific. However, Chinese ornithologist Tso-hsin Cheng treated them as two distinct species, as they had breeding grounds which did not overlap, and he had seen no evidence of hybridisation. While the species was long thought to have arisen from eastern populations of the ferruginous duck, American ornithologist Paul Johnsgard says its behaviors suggest it may instead be more closely related to the hardhead.
American ornithologist Bradley Curtis Livezey published a phylogenetic study based on morphological data in 1996, in which he proposed his view on the relationship among Tribe Aythyini. Baer's pochard, ferruginous duck, hardhead and Madagascar pochard are classified in subgenus Nyroca (the "white-eyes"), intrasubgenus relationship is unclear, but the ferruginous duck was suggested to be the sister group of Baer's pochard. The subgenus Aythya (the "scapu", including New Zealand Scaup, ring-necked duck, tufted duck, greater scaup and lesser scaup) is the sister group of subgenus Nyroca. The subgenus Aristonetta (the "redheads", including the common pochard, canvasback and redhead) is the sister group of all other pochards.
Two molecular phylogenetic studies on Anseriformes or Anatidae were published in 2000s, some mitochondrial genes were sequenced, but Baer's pochard was absent in both of them. The mitochondrial genome of Baer's pochard was sequenced and published in 2021. Molecular phylogenetic studies determined the relationships among Baer's pochard and other closely related species:

Description
The Baer's pochard is 41–47 cm (16–19 in) long with a 70–79 cm (28–31 in) wingspan. The male is slightly larger, weighing on average 500–730 g (18–26 oz), wings lengthed 18.6–20.3 cm (7.3–8.0 in), tail at 53–60 mm (2.1–2.4 in), and culmen at 38–44 mm (1.5–1.7 in). Relatively, the female weighing on average 590–655 g (20.8–23.1 oz), wings lengthed 19.1–20.5 cm (7.5–8.1 in), tail at 51–64 mm (2.0–2.5 in), and culmen at 40–44 mm (1.6–1.7 in). Both male and female's tarsometatarsus lengthed 33–34.7 mm (1.30–1.37 in).
Breeding male has a black head and neck with green gloss, white or paler yellow eyes, blackish-brown back, dark chestnut breast, white or light chestnut flanks and a short and low tail. The green gloss on its head is unique among Aythya. While it is likely to look completely black in poor light. Female has a dark brown head and neck that blend into the chestnut-brown breast and flanks. Eclipse and first-winter male resembles female, but retain the white eyes, while female has brown eyes. Both male and female have wide white speculum feathers, white vent-side, dark-grey bill, black nail and dark-grey tarsometatarsus.
It is similar to its close relative, the ferruginous duck (A. nyroca), both have white vent-side and iris in males, black nail, and wide white speculum feathers. Although Baer's pochard is bigger, has a longer head, body and bill. Unlike the ferruginous duck's tall and triangular head, Baer's pochard has a more rounded head and a flatter forehead. The white part on the belly extends to its flanks in Baer's pochard, which is visible when floating on the water, while the ferruginous duck has a smaller white part on its belly. The female Baer's pochard has a distinctly bright chestnut spot at the lore, which is absent in ferruginous duck.
Baer's pochard is usually a quieter duck, but during its courtship display, both sexes give harsh graaaak. Females may give kura kura kura and males may give kuro kuro at other times.
Distribution
Baer's pochard traditionally bred in the Amur and Ussuri basins in Northeast China and the southeastern Russian Far East. In recent years, it has also colonised North China and Central China. It winters in most areas south of the Yellow River in China, Taiwan, Japan, Bangladesh, India, North Korea, Laos, Myanmar, Nepal, Thailand and Vietnam, and occasionally appears in Bhutan, South Korea, Philippines or Pakistan as a rare vagrant. It leaves its wintering grounds by mid-March and returns to them by mid-October or early November.
The species has become extremely rare in its traditional breeding areas, and since 2010, there have been no confirmed breeding reports in all sites north of Beijing. However, the numbers recorded during the breeding season are smaller than those recorded in winter, so there may still be unknown breeding sites. For example, there are some doubtful breeding reports in the Chinese part of Lake Khanka, the Russian part of Lake Khasan, and the Muraviovka Park [ru]. Since 2012, new breeding sites have been discovered in several provinces of China, including Hebei, Hubei and Jiangxi; the latter two cities are far from traditional breeding sites in the Amur and Ussuri basins.[1] In these new breeding areas, warmer climate conditions provide a longer breeding season (about twice as long as in the Amur and Ussuri basins) which allows birds to lay a replacement clutch if their first clutch fails. Baer's pochard is no longer migratory in central and eastern China.
The wintering grounds have also contracted significantly in recent years. Since at least the winter of 2010-2011, Baer's pochard no longer winters in any site outside mainland China, except as a vagrant. In its wintering grounds in mainland China, the population has also declined severely, by more than 99%.
Behaviour and ecology
Baer's pochard is a shy species, that inhabit open, slow-flowing lakes, swamps and ponds. It breeds around lakes with rich aquatic vegetation, nesting in dense grass, flooded tussock meadows, or flooded shrubby meadows. In winter, it forms large flocks on large and open freshwater lakes and reservoirs with other pochards. It has strong wings, and can flyor walk at high speeds. It is also good at diving and swimming, and can quickly take off from the water when threatened or disturbed. In migrating season, they form small groups of more than 10 or dozens of birds, flying at low altitudes in wedge-shaped formations. During winter, Baer's pochard sleeps during the day, leaves for unknown feeding sites with other ducks in the dusk, and returns before dawn. Little is known about their diet beyond aquatic plants, grass seeds and molluscs.
Breeding
Baer's pochard appears to have a monogamous mating system, at least within a breeding season. In traditional breeding grounds in northeastern China, Baer's pochard gathers in gaps in the ice before it completely thawed. After the ice season, it gathers on the large, open lakes. They breed from mid-to-late May. While in Fuhe Wetland in Wuhan, Hubei, Baer's pochard gathers in large groups on the open lakes before breeding season. It is divided into small groups in mid-April, in which they will courting and mating. During courtship, the male swims around the female, repeatedly nods his head up and down. When other males approach, it swims toward them quickly to drive them away, but there is no violent fight between them. The female also nods her head in response. When the male approaches, the female straightens her neck and lowers her head to the water. He then climbs onto her body and bites her nape feathers to mate. After the mating, the male and female leave the flock for nesting.
Baer's pochard's nest is circular cylindrical, located among emergent vegetation, usually in shallow water or on small islands or ridges. The nest is made of sedges, reeds and other plants collected from the immediate vicinity, lined with a layer of down. Its clutch ranged from 5 to 14, with an average of 9.7. Males usually take on sentry duty at about 10 meters from the nest during hatching. Females leave the nest to forage 2–3 times a day, usually during 6:00-20:00, and lasted for 27–240 min. They cover the eggs with nest materials during forging, and place them onto their back when coming back. If water levels are elevated by heavy rainfall or human activity, females increase the height of the nest to avoid flooding. During the hottest days, females often stand on the nest and shelter eggs from the strong sunlight, whilst allowing circulation of air around them. Females also take water into their plumage and use it to cool the eggs. The incubation lasted for 23-26 days.
Studies have shown that the nest survival rate[note 3] of Baer's pochards is about 14–45%, and each clutch may lose one to nine eggs. About 20-30% of eggs hatched successfully, and 3–16 young fledged per nest. There are three major reasons contributing to the failure, including nest desertion (abandoned by parents), nest predation (mainly by Siberian Weasels) and flooding. The proportion of these causes varies among years. In addition, most of the breeding sites in Wuhan are Crayfish farms, the farming work and eggs collection may also be hindrances.
Biological interaction
Incomplete inter- and intra-specific brood parasitism were found in Baer's pochard. In Xianghai National Nature Reserve [zh], Baer's pochards could parasitize gadwall and common pochard, and may be parasitized by common pochard. In Wuhan, Baer's pochard shares breeding sites with cotton teal, eastern spot-billed duck and mallard. Interspecific brood parasitism was not observed. Intraspecific parasitic was found in Wuhan. If caught, the parasite will get attacked by the host.
Baer's pochard has hybridized with lesser scaup, common pochard, ferruginous duck, New Zealand scaup, chestnut teal and wood duck in captivity. Ferruginous duck was observed displaying to Baer's pochards several times in China and South Korea. Some individuals showed mixed characteristics of common, ferruginous and Baer's pochards, so they may be currently hybridising in the wild. The Baer's pochard has declined sharply in recent years, but the ferruginous and common pochard has expanded their breeding grounds, and even to the core areas of Baer's pochard's, which makes the hypothesis possible.
The research on its gut microbiota showed that the richest microorganism phyla of Baer's pochard are Bacillota, Pseudomonadota and Bacteroidota, which were consistent with those of the domestic goose, duck and chicken. The gut microbiota in diarrheic Baer's pochard is low in diversity, and the species were also significantly different from healthy individuals. Most species in reduced numbers are thought to be intestinal beneficial bacteria.
Threats and protection
Baer's pochard was once a common species in its range, but is now very rare. Mature individuals may be less than 1,000. According to records in China, there were 16,792 wintering individuals from 1986/87 to 1992/93, but only 3,472 from 1993/94 to 1998/99, and only 2,131 from 2002/03 to 2010/11. Bangladesh had more than 3,000 in 1996, India had more than 1,400 in 1995 and 1997, Myanmar had about 500-1,000 in the 1990s, and 596 were counted in 1998 in Thailand. While by 1999/00-2004/05, only 719 were counted in all wintering grounds except China, and only 48 individuals in 2005/06-2010/11. In China, hunting and habitat loss were considered to be the main threats. From 336 to 4,803 pochards were hunted annually in Honghu, Hubei from 1981 to 1997; in areas near Rudong County, maybe 3,000 are hunted every year. The wintering grounds have been significantly changed due to water pollution, fishing management, changes in aquatic plants, and the changing ecology of many wetlands in the Yangtze River floodplain. Factors in breeding and migrating grounds may also have contributed to its decline. The global decline shows no sign of slowing or stopping.
Baer's pochard was formerly classified as a vulnerable species by the IUCN. Recent research has shown that its numbers are decreasing more and more rapidly, and it was consequently uplisted to endangered status in 2008. In 2012, it was further uplisted to critically endangered. In 2014, the East Asian–Australasian Flyway Partnership (EAAFP) drafted the Baer's Pochard Task Force and it was endorsed in Jan 2015. Baer's pochard was listed as a first-class protected animal in China by 2021. In 2022, media reports state that the first captive population in China was established in the Beijing Zoo, with totally 54 individuals. It is planned to be further expanded and used for reintroduction.
A study published in 2022 showed that most breeding sites (81.8%) and suitable habitats (94%) are not located in protected areas, and overlap with large cities. Current protected areas may be less effective for the conservation under predicted global climate change, closely coordinated cross-border cooperation would be critical for Baer's pochard

The male and female remain colourful throughout the year, lacking an eclipse plumage. The drake has a rich chestnut back, pale grey flanks and a salmon-coloured breast speckled in black. A black band runs from the top of its head down to the nape. Females have an olive-brownish back with the head blotched and striated in white, with pencilled barring on a pale chest and belly. Both have a dark tail, a contrasting pale rump, and a distinctive white patch on the wing. Bills are grey and legs and feet are pink in both sexes. Pairs easily bond. Their contact calls are a cat-like mee-oowing in ducks, a lingering peewoo in drakes.
The Ringed Teal (Callonetta leucophrys) is a small duck of South American forests. It is the only species of the genus Callonetta. Usually placed with the dabbling ducks (Anatinae), this species may actually be closer to shelducks and belong in the subfamily Tadorninae; its closest relative is possibly the Maned Duck. female The male and female remain colourful throughout the year, lacking an eclipse plumage.
HABITAT AND RANGE: Ringed Teal ducks are found in South America, from southern Bolivia, Paraguay, and southwestern Brazil to northeastern Argentina and Uruguay. Their habitats include tropical, swampy forests and marshy clearings in well-wooded lowlands, as well as secluded pools and small streams. PHYSICAL CHARACTERISTICS: Roughly translated, the Latin name of the Ringed Teal, Callonetta leucophrys, means “the beautiful duck with the white wing patches.
Ringed teal have strong, pointed claws on their feet and so can readily perch in trees. Length: 14-15 inches Weight: 11-12 ounces Coloration: Ringed Teal, typical of wood ducks, have beautiful iridescent greenish plumage patterns, especially on the wings. They may be distinguished by a white patch in front of the green speculum. The males have a finely speckled, pinkish breast and a buff colored head with a black posterior border, they can dive underwater to escape predators. However, they seldom dive deeper than one meter. While swimming, they hold their tails horizontally so that they do not touch the surface of the water. After dabbling, they flap their wings vigorously a few times to shake out any water that might have entered the wing pockets or other air spaces.
The ringed teal live in South America, from southern Bolivia, Paraguay and southwestern Brazil to northeastern Argentina and Uruguay in wooded habitats. They have strong, pointed claws on their feet so they can readily perch in trees. Their length can be up to 14-15 inches with a 28 inch wingspan and weight of 11-12 ounces.

Anser serrirostris
The tundra bean goose (Anser serrirostris) is a goose that breeds in northern Siberia. This and the taiga bean goose are recognised as separate species by the American Ornithological Society and International Ornithologists' Union, but are considered a single species by other authorities (collectively called bean goose). It is migratory and winters further south in Asia. The taiga and tundra bean goose diverged about 2.5 million years ago and established secondary contact ca. 60,000 years ago, resulting in extensive gene flow.
Rather large, dark gray-brown goose with typically small orange patch on bill, and orange legs. In flight lacks contrasting pale forewing areas of Pink-footed Goose and Graylag Goose. Not always safely told in the field from Taiga Bean Goose, but Tundra averages a shorter and thicker bill, vs. the longer, more sloping bill of Taiga. Breeds on tundra and winters in farmland and wetlands, where it associates readily with other geese.
The length ranges from 68 to 90 cm (27–35 in), wingspan from 140 to 174 cm (55–69 in) and weight from 1.7–4 kg (3.7–8.8 lb).[2] In the nominate subspecies, males average 3.2 kg (7.1 lb) and females average 2.84 kg (6.3 lb).[2] The bill is black at the base and tip, with an orange band across the middle; the legs and feet are also bright orange.
The upper wing-coverts are dark brown, as in the white-fronted goose (Anser albifrons) and the lesser white-fronted goose (A. erythropus), but differing from these in having narrow white fringes to the feathers.
The voice is a loud honking, higher pitched in the smaller subspecies.
The closely related pink-footed goose (A. brachyrhynchus) has the bill short, bright pink in the middle, and the feet also pink, the upper wing-coverts being nearly of the same bluish-grey as in the greylag goose.

Physical characteristics
Size is similar to the Mute Swan, but there are noticeable differences. Whooper Swans have a yellow and black beak, a more rigid neck bearing in activiy as well as at rest, and, finally, their wings produce a musical sound when they fly. Their feathers are entirely white and their webbed feet are black. Juveniles show a greyish brown plumage. After one year, they get their adult one.
The Whooper Swan can also be mistaken for the Bewick Swan whose he's very close. There are two ways to differentiate them: the Whooper Swan is much bigger, with a longer neck and a more angulous head, and the beak's yellow/black layout is different. While the Whooper's Swan beak looks globally yellow with just a black tip, the Bewick's Swan's one is mainly black with a yellow base, sometimes half yellow, half black. Unlike the Mute Swan, it never raises its wings above its back when it swims and its neck is straighter.
Habitat
Winters on low agricultural land, generally not far from coast. Breeds in northern zones, on shallow fresh waters: pools, lakes and rivers in wooded country. Rarely in tundra.
Other details
Cygnus cygnus breeds mainly in Iceland, Fennoscandia and northern Russia, but winters patchily across much of Europe, which constitutes >50% of its global wintering range. Its European wintering population is relatively large (>65,000 individuals), and was stable between 1970-1990. Although there were declines in a handful of countries during 1990-2000, most European wintering populations-including key ones in Denmark and Germany-were broadly stable or increased, and the species underwent a large increase overall.
Whooper Swans nest mainly in Eurasian boreal regions. They split in three distinct groups. The most occidental one, with a stable population of about 16 000 individuals, nests in Iceland. The central one nests in Scandinavia and Occidental Russia. It is estimated at 59 000 individuals, regularly increasing. The most oriental group is located in Siberia. Its population, estimated at 17 000 individuals, is probably decreasing. These groups migrate south beginning autumn with the first cold days. The occidental group leaves Iceland for the British Isles, North Sea and Channel coasts, as far as the farthest point of Brittany. The oriental group sets up on Caspian and Black Sea shores. The Scandinavian group is the one that has the shortest migration. During winter, Whooper Swans, like Bewick Swans, spend a great deal of time grazing.
Feeding
Essentially vegetarian. It eats aquatic plants and uses all parts of it (stems, leaves, roots, shoots). It also graze in prairies, like geese. It may eat small invertebrates, but it's a minor part of their diet.
Conservation
This species has a large range, with an estimated global Extent of Occurrence of 10,000,000 km². It has a large global population estimated to be 180,000 individuals (Wetlands International 2002). Global population trends have not been quantified, but the species is not believed to approach the thresholds for the population decline criterion of the IUCN Red List (i.e. declining more than 30% in ten years or three generations). For these reasons, the species is evaluated as Least Concern. [conservation status from birdlife.org]
Breeding
Pairs unite for lifetime. Males are very active in nest building. Their nest is bulky and made essentially with stems and leaves. The bottom is covered with twigs, leaves and feathers. In April-May, the female lays 4 to 7 eggs and sits on for 5 to 6 weeks. Chicks are precocious and are carried on the female's back under the male's aggressive watch and protection. Taking flight occurs 87 to 90 days after hatching.
Migration
Migratory. Part of Icelandic population remains in winter. Migrates southwards to temperate areas, sporadically in more southern latitudes in cold winters; vagrant to USA and Pakistan.

Many birds are very cryptic around their nests, leaving only in the early morning or late evening. Swans take many recess throughout the day and are not cryptic it all. Of course it is hard to hide yourself when you plumage is completely white and you build a nest that averages 7 feet around.

FamilyDucks and Geese
HabitatMarshes, lakes, bays, fields. In summer mainly on inland marshes, especially larger marshes, not often at small ponds. In migration and winter on coastal estuaries, fresh or salt marshes, inland lakes and ponds. May winter on large deep lakes.
While most dabbling ducks are denizens of the shallows, American Wigeon spend much of their time in flocks grazing on land. Paradoxically, they also spend more time than other marsh ducks on deep water, where they get much of their food by stealing it from other birds such as coots or diving ducks. This duck was once known as "Baldpate" because of its white crown.
Feeding Behavior
Versatile in foraging. Flocks often feed on land; feed in shallow water, taking items from surface or submerging head and neck; also associates with diving birds on deeper water, robbing them of their food when they come to the surface. May feed by day or night.
Eggs
8-11, sometimes 5-12. Whitish. Incubation is by female only, 23-24 days. Male usually departs before eggs hatch. Young: Leave nest shortly after hatching, feed themselves. Female remains with brood for much of their pre-flight stage. Young capable of flight 45-63 days after hatching.
Young
Leave nest shortly after hatching, feed themselves. Female remains with brood for much of their pre-flight stage. Young capable of flight 45-63 days after hatching.
Diet
Mostly plant material. Eats aquatic plants such as pondweeds, sedges, wild celery, eelgrass, algae. Also eats some insects and snails. On land, grazes on young grass shoots, and consumes seeds and waste grains. Very young ducklings eat many insects.
Nesting
Pair formation begins on wintering grounds; most older birds paired before spring migration. Several males often court one female. In one display, male extends neck forward with head low, bill open, while raising tips of folded wings, revealing white wing patches. Tends to begin nesting later in season than most dabblers. Nest site on dry land, sometimes on island, usually within 100' of water but sometimes up to 1/2 mile away; site concealed by tall vegetation. Nest (built by female) is shallow depression filled with grasses and weeds, lined with down.
Migration
Migrates in flocks, and may travel mostly by day. In summer, when males leave their mates, they may fly great distances to large open marshes where they will stay while going through the flightless stage of their molt. In western U.S., southward migration seems to be gradual, with numbers in southern California not reaching peak until December or January.
Songs and Calls
Distinctive whistled whew-whee-whew; also quacks.

Physical characteristics
Wood Ducks are intermediate in size, between the Mallard and Blue-winged Teal; on average, males weigh 680 g and females weigh 460 g. From a distance, the male Wood Duck on the water appears as a dark-bodied, dark-breasted, light-flanked duck with a striped crested head and a light-coloured throat. At close range, its iridescent plumage, red eyes, and black, red, and white bill are conspicuous. A white eye-ring, light-coloured throat, and fine crest distinguish the female from both the male Wood Duck and females of other species. Both sexes usually show a downward pointing crest at the back of the head, and their long broad square tails are distinctive features in flight.
The wings of Wood Ducks are highly characteristic. The primary wing feathers, which are the 10 outermost flight feathers attached to the wing beyond the wrist, are dark in colour. The outer vanes of these feathers look as if they have been sprayed with aluminum paint. The Wood Duck is the only North American duck so marked.
In most cases it is possible to distinguish immature from mature ducks and to tell males from females by their wings alone. In the Wood Duck, as in other ducks, the feathers of that year's young are finer, more pointed and worn, and less colourful than those of adults. Females show a few small feathers on the upper surface of the wing that are purplish and have the same lustre as oil on water. These feathers are absent in males. The white tips on the feathers along the trailing edge of the wing are usually teardrop-shaped in the female, but either straight or V-shaped in the male. By studying the wings of ducks taken by hunters, biologists can determine the ratio of young to adult ducks in the population and thereby measure waterfowl production.
The Wood Duck is a distinctively North American species. Its only close relative is the Mandarin Duck of eastern Asia. Evidently the Wood Duck originated in North America, as fossil remains have been found only in widely scattered locations in the eastern part of the continent.
Habitat
Like other perching ducks, Wood Ducks nest in trees. Preferred nesting sites are holes in hollow trunks or large branches that result from broken limbs, fire scars, lightning and logging damage. They also use cavities created by large woodpeckers such as the Pileated Woodpecker. Nests are situated from 1 to 15 m above ground, in trees more than 40 cm in diameter. They are usually found close to water, although females sometimes select trees some distance from water.
Other details
In Canada, the Wood Duck nests in scattered locations in the southern parts of all provinces; however, there is only one breeding record for Newfoundland and Labrador. The most extensive breeding ranges are in Ontario, Quebec, New Brunswick, and British Columbia. This duck occurs over a much wider area in late summer and early autumn, as a result of post-breeding dispersal. Although most Wood Ducks migrate to the United States, a few may spend the winter in extreme southern Ontario and southeastern British Columbia.
The Wood Duck is much more widely distributed in the United States, where it nests in areas east of the Mississippi River, along the lower Missouri River into South Dakota, in eastern Texas, along the Pacific coast, and in a few other places. It winters mainly along the Atlantic coast from New York south, along the Gulf coast into central Texas, to the lower Mississippi River valley and western California. A few winter in Mexico south to Distrito Federal. In Europe all sightings are of escaped birds.
Feeding
The Wood Duck is mainly a herbivore, or vegetarian, with plant foods making up about 90 percent of its diet. Foods vary according to their local availability, but duckweeds, cypress seeds, sedges, grasses, pondweeds, and acorns are among the more important foods throughout North America. In recent years corn has assumed a greater importance as small groups of Wood Ducks engage in field feeding behaviour similar to that of dabbling ducks, such as Mallards.
Ducklings require a high protein diet for rapid growth. Invertebrates such as dragonflies, bugs, beetles, and spiders are important foods during the first few weeks of life, so high populations of these small creatures are essential in habitats where the young will hatch and develop.
Conservation
This species has a large range, with an estimated global Extent of Occurrence of 6,200,000 km². It has a large global population estimated to be 3,500,000 individuals (Wetlands International 2002). Global population trends have not been quantified, but the species is not believed to approach the thresholds for the population decline criterion of the IUCN Red List (i.e. declining more than 30% in ten years or three generations). For these reasons, the species is evaluated as Least Concern. [conservation status from birdlife.org]
Breeding
The female Wood Duck breeds when one year old. She lines the nest with down, or fine feathers, taken from her breast, and lays eight to 15 dull-white to cream-coloured eggs. She incubates, or keeps the eggs warm, for 28 to 30 days until they hatch. During unusually cold weather, or if the female is away from the nest for an abnormally long time, incubation may require a few extra days.
Upon hatching, usually in June in eastern Canada, the young use their sharp claws to climb up the inside of the nesting cavity to its entrance, then jump and flutter to the ground, generally landing unharmed. The female guides them to the nearest water, where they will spend the next eight to nine weeks hunting for food together.
Shortly after the female begins incubation the male loses interest in family affairs and spends more time away from the nest. He joins other males, which eventually form large groups. As mid-summer approaches, the males begin the move to remote, undisturbed, sheltered places to moult, or shed old feathers. To reach these areas, they may travel great distances; many thousands migrate to southeastern Canada from breeding grounds in the northern states. On arrival the moult begins, and by August the brilliant spring feathers of the male have been replaced by a plumage similar to that of the female. Then, all at once, the flight feathers are moulted, leaving the male flightless for approximately four weeks while new feathers grow in.
Soon after the ducklings have fledged, or taken their first flight, usually by mid-August in eastern Canada, the females leave their broods, move a short distance, and undergo their moult. Like the males, they too seek out remote, undisturbed swamps and marshes and become flightless for a short period.
In late summer and early autumn, the young with their newly acquired powers of flight and the adults with their recently replaced flight feathers move in a leisurely way about the northern parts of their range. Their principal concern is to store up energy, in the form of fat, in preparation for the soon-to-come fall migration.
Migration
Wood Ducks migrate north to their Canadian breeding grounds, arriving there by April. Pair formation may occur on the wintering grounds before or during spring migration, or on the breeding grounds if one of the pair is lost. Mated pairs seek out secluded swamps or beaver ponds that provide water, nesting sites, brooding habitat, and feeding areas. Females often return to the same general area in which they were hatched.
By the first severe frost, usually in late September or early October in eastern Canada, Wood Ducks begin to head for the southeastern United States. Southern populations of Wood Ducks, particularly females, are less migratory. Populations in the interior of British Columbia migrate to the west coast, whereas Wood Ducks that live on the coast do not migrate at all. Has occurred Bermuda (regular), Azores and Alaska. Many sightings from Europe, presumed escapes.
