I always find it difficult to differentiate between Greater and Lesser Yellowlegs, particularly when they are not both present. I think this is a Greater but will defer to the experts out there.

As always, thank you so much for stopping by and for leaving any comments or faves, they are very much appreciated.

Adult Roesel's bush-crickets are medium-sized Tettigoniid between 13–26 mm in length. They are normally brown or yellow, often with a greenish shade and a rarer green form also sometimes occurs. An identifying feature is the yellow-green spots along the abdomen, just behind the pronotum, along with a matching margin along the border of the pronotum. This margin is entire, unlike the bog bush-cricket.
Males and females can be easily differentiated, as the females have a long sword-like ovipositor at the end of their abdomen, which the males lack.

Other common names: Pechiblanco toucan, red-billed toucan.
Habitat: This species can be found in South America in countries such as: Brazil, French Guiana, Guyana, Venezuela, Bolivia, Ecuador and Colombia.
In Ecuador they live in the Amazon region, in humid forests in the lowlands and in the eastern foothills.
Altitude range: Mainly below 900 meters above sea level.
Dimensions: Length 53.5 - 57 cm.
Weight: Between 600 - 650 gr.
Feeding: It feeds mainly on a variety of fruits, also flowers, nectar, insects, small reptiles such as lizards and bird eggs.
Nesting period: 14 to 15 days. 2 to 4 eggs, nest in the hollows of the trees.
Life expectancy: Approximately 11 years.
Sounds: The projected claim of this toucan is one of the most characteristic sounds of the Ecuadorian eastern birdlife, it consists of a phrased cry (voice noise that is loud and confusing).
Description and behavior: They have a very long peak of 18-21 cm, mainly black with yellow tip, top and maxillary base; Celestial mandibular base. Mainly black body with yellow rump, low red area, throat and white chest bordered below by a red band.
A similar species is the Piquiacanalado Toucan, they are identical in plumage and beak color, they are easily differentiated by their very different voices; Differences in size are most evident when both species are together. In general, goliblanco toucans are more numerous.
Threats: Habitat loss, deforestation, illegal hunting and illegal wildlife trafficking.
Conservation status: Expands the network of protected areas to effectively protect IBAs (Important birds areas). Conservation on private lands is also essential, by expanding market pressures for good land management and preventing logging of forests on land unfit for agriculture.

It is difficult to believe that Wren is the commonest breeding bird in Britain with 11 million pairs. Most other common British birds such as Blackbird (5.1 million pairs), Robin (7.4 million), Woodpigeon (5.2 million) and House Sparrow (5.3 million) are restricted to certain habitats. But Wrens can breed in almost any habitat, from wetlands and woodlands to the high moorlands, and you don’t see many other “common” birds on the moors. I photographed this one high on the Peak District moors in the heather after a light fall of snow.
And the title; "Winter Wren?" Winter Wren was the “official” name of our British Wren for a brief period around 2010 when we were trying to standardise bird names to reflect their global distribution. I remember an American once said to me it was arrogant of the British to simply call this "the Wren” when it was one of many wren species, and that it had a perfectly good name to differentiate it from the others; Winter Wren. But recent DNA work has resulted in the American Winter Wren being split into two species, that are both different from the one we get in Britain and Europe. So the “official” name is now Eurasian Wren, which was named first by Linnaeus and so retains the scientific name Troglodytes troglodytes, while the Winter Wren is now T. hiemalis in the east of America, and Pacific Wren (T. pacificus) in the west (Hiemalis means "of the winter", because this species remains in the northern forests of the USA and Canada whereas the similar House Wren tends to migrate south). There was strong evidence of reproductive isolation between the two American species and it was calculated that Pacific Wren and Eurasian Wren last shared a common ancestor approximately 4.3 million years ago.
La couleur des pattes ( verdâtres ) est le principal critère qui permet de le différencier du Bécasseau semipalmé ( noires ).
The color of the legs (greenish) is the main criterion that differentiates it from Semipalmated Sandpiper (black).
A big swell tonight.. at least 2.5m and high tide so I went to Mona Vale pool for the first time. The concept I was looking for really came off with the lights illuminating the pool and the big swell coming in behind. The "tilt shift effect" wasn't deliberate or done in post.
The pool is some distance from shore and has its own lighting. There are two Rockpools - one suitable for toddlers and a larger pool measuring 30 metres for bigger kids and adults

Parking is 5 seconds away. Unfortunately no lightning or really differentiated clouds (I guess that a rainbow would have been sweet too) but still some great shots to share. It wasn't intentional to upload them all at the same time.
General information on ocean pools in Sydney:
The Common Tiger is one of the common butterflies of India. It belongs to the brush-footed butterflies family. The butterfly is also called Striped Tiger in India to differentiate it from the equally common Plain Tiger (Danaus chrysippus).
The Common Tiger is distributed throughout India, Sri Lanka, Myanmar and extending to South-East Asia and Australia (except New Guinea). At least in the South Asian part of its range it is fairly common, locally very common.
This butterfly occurs in scrub jungles, fallowland adjacent to habitation, dry and moist deciduous forests, preferring areas of moderate to heavy rainfall. Also occurs in degraded hill slopes and ridges, both, bare or denuded, and, those covered with secondary growth.
While it is a strong flier, it never flies rapidly or high. It visits gardens where it nectars on the flowers of Adelocaryum, Cosmos, Celosia, Lantana, Zinnia, and similar flowers.

A small, green, long-tailed parakeet endemic to New Zealand. Note the distinct lemon-yellow crown and the thin orange band extending from the base of the beak to each red eye. Juveniles are a duller color and their orange band and crown may be absent. A critically endangered bird now restricted to three beech forest valleys in inland Canterbury and several offshore island sanctuaries. Usually very quiet and challenging to see. Listen for its loud, brief chatter call to give away its location. When pairs are together, softer contact calls can be heard. Forms small flocks in autumn and winter. Smaller size and lack of crimson frontal band and rump patches distinguish Malherbe’s from Yellow-crowned Parakeet. Juvenile Yellow-crowned Parakeet can confuse identification, and calls of the two species can be challenging to differentiate. (eBird)

One of the goals of the Marlborough Sound trip was to visit Blumine Island in search of this critically endangered parakeet. Not an easy process, as disembarking the boat involved climbing down a ten foot step ladder leaning against the bow of the boat then wading through the surf onto the beach. Still, as you can see, we did find the bird (in this case two), sitting deep in the forest. I've rather inexpertly removed two OOF twigs from in front of the bird, to better show how beautiful it is.

For comparison, here are Common v. Slender baskettails from same location & same day this week. Common's can have a LOT more black in their wings but most of the ones I've been seeing have wings more like E. costalis (see below). They're very difficult to differentiate in-flight: Slender's are a bit larger and Common's have different behavior.

There is differing opinions but Cooper's hawk (Accipiter cooperii) wins over Sharp-shinned. I do know this visitor was drinking not bathing. The two squirrels hiding in the adjacent maple tree beat a hasty retreat when a passing car and walker, spooked the hawk. The street is ~ 15 yards ( 15 m) behind it. The Cornell Lab has a special page of differentiating between Cooper's and Sharp-shinned that can be found here: feederwatch.org/learn/tricky-bird-ids/coopers-hawk-and-sh...
A small colorful bird that looks 90% similar to the common Tickell's blue flycatcher, but is very uncommon and reported rare in our region. The only differentiation is the throat color which is dark blue for this bird, orange for the Tickell's. The calls too are almost similar between the birds.
I had this view that bird is a migrant from Northern India, Pakistan / Himalayan ranges and migrates to South India during winters. But I suspect there is a resident population in the state in the forests in the northern parts where we can see during summer. I don't remember anyone sighting a nest yet, if that is sighted, it would confirm that it a resident.
This flycatcher is found in thick wooded regions and forests and tends stick to thick canopy areas and dense undergrowth near wet areas. We sighted this in a forest on the side of a hill overlooking a temple. There was a broken water pipe that had small drops rolling down the slope into the undergrowth. And that place had like 5-6 flycatchers and around 15+ birds in total - all close to the ground. The water pooled and stagnated resulting in a lot of flies / insects and thats what attracted the flycatchers I suppose.
Many thanks in advance for your views and feedback. Much appreciated.

► █░▓ THREE MINUTES OVER to the official sunset for the date and place (21:50 at 305º NW).
Just before the next sunrise my son will become 23 years of age.
Sun is slowly but resolutely "working" towards its northernmost sunset point on the horizon, which will happen in less than three weeks (summer solstice, 21 June at 22:02; in most locations north of the equator, this is the longest day of the year. However, the latest sunset is on 25 June, 22:03.). The point on this capture is already advanced enough - the sun has already reached Molenaarsgraaf en Vuilendam presumably, seen here just to the right of sun in the picture.
I was late, and the sun sets quickly so I had no time to set the curve in the camera to -3/+3 or -5/+5 as usually. So the capture had to be grossly underexposed to preserve any color of the sun itself. Aperture priority, set full open for the longest throw of the zoom lens. Handheld, supported by the window frame. Full frame equivalent of 800mm. Developed from raw and edited in Affinity Photo 1.10.5. Uncropped. Had to fiddle a lot with the curves to get the colors differentiate. The sooc jpeg of this shot is practically monochromatic.

This Western Grebe was fishing near the boat ramps in San Leandro Marina. We followed it up and down the small channel as it kept diving for food. Every now and then it stayed still long enough for us to capture a couple of pictures. The western grebe is the largest North American grebe. Large, slender grebe with long straight bill. Dark cap extends below eye, differentiating it from the Clark’s Grebe. Its bill is a fairly dull yellowish-green.
A resident shrike species - the most beautiful of the 3-4 we have here and a common bird in the countryside. They are easy to id and differentiated from their 2 other cousins by the thick brownish red coat on their backs. Size wise, they are the smallest and easy to distinguish visually.
Apart from the minor coloration difference, behaviour wise they are very similar the Long Tailed Shrike and Brown Shrike, though the Long tailed Shrike is the biggest of all. The Bay Backed Shrikes are found in the grassland kind of habitats where they are often sighted perched on dry twigs and hunting close to the ground. Like all the other shrikes, they are an aggressive lot and often involved in territorial fighting with Bulbuls or Drongoes or the Long tailed Shrikes.

Regione Marche - Italia
Nata il 14 dicembre 2004, la Riserva Naturale Regionale Sentina è la più piccola area protetta marchigiana, ma con una grande valenza ambientale.
Un paesaggio di acqua e sabbia che si sviluppa per circa 180 ettari all'interno del Comune di San Benedetto del Tronto, tra l'abitato di Porto d'Ascoli a Nord e il fiume Tronto a Sud.
La Sentina è costituita da ambienti unici come cordoni sabbiosi, zone umide retrodunali, e praterie salmastre che ospitano una ricca e peculiare flora ormai scomparsa in quasi tutto il litorale adriatico devastato dall'antropizzazione.
Notevole è l'importanza dell'area per l'avifauna migratoria, che trova nella Riserva l'unica possibilità di sosta costiera tra le aree umide del delta del Po e del Gargano.
English version
The Sentina Natural Regional Reserve was established in 2004 by a regional law and is the smallest Park in the Marche region.
For the natural organization of the places, Sentina is considered a homogeneous system of land, river, and lake areas, a landscape of waters and sand covering an area of 177.55 ha, entirely in the territory of the Municipality of San Benedetto del Tronto, between the town of Porto d'Ascoli in the north and the river Tronto in the south, between the coastline in the east and the railway line in the west.
Sentina Regional Nature Reserve represents for San Benedetto del Tronto an invaluable treasure for its natural environments, life quality, and a differentiated tourist offer completing the already existing proposals offered by the seaside tourism.
Hobart is the capital and most populous city of the Australian island state of Tasmania. With a population of approximately 240,342 (over 45% of Tasmania's population), it is the least populated Australian state capital city, and second smallest if territories are taken into account (after Darwin, Northern Territory). The city is located in the state's south-east on the estuary of the River Derwent, making it the most southern of Australia's capital cities. Its skyline is dominated by the 1,271-metre Mount Wellington, and its harbour forms the second-deepest natural port in the world, with much of the city's waterfront consisting of reclaimed land. The metropolitan area is often referred to as Greater Hobart, to differentiate it from the City of Hobart, one of the five local government areas that cover the city. Founded in 1804 as a British penal colony, Hobart is Australia's second oldest capital city after Sydney, New South Wales. 30921
A spectacular sunbird around 11 cms long and one is that was very challenging to shoot for me so far. The bird has a bright crimson coloron the upper part of the body and hence is easy to sight. The crimson is brightest around the breast area, while the color on the back is slightly pale. The females are yellowish olive and lack the color of the male. In fact, many female sunbirds look similar and are hard to differentiate from a distance.
They are often sighted around flowering plants, bushes and on trees with small buds. The birds prefer the nectar in the flowers, but during non-flowering seasons, prefer to hunt spiders and other insects. They are a delight to watch, but the birds are very shy and it is really hard to get a decent shot of them. This is the best I could manage after more than half a dozen visits.
Thanks in advance for your views, feedback and faves - much appreciated.

Europe's grey squirrels (Sciurus carolinensis) originated in North America, where they are known as eastern grey squirrels (to differentiate from western grey squirrels). They eat large seeds, flowers, buds, fruits, fungi, some insects and occasionally bird eggs.
They were first introduced into England, in a concerted way, in 1876, and through rapidly growing population and further introductions they spread to the rest of Great Britain by the early to mid-20th century. The eastern grey squirrel was introduced to Continental Europe in 1948 and has quickly taken advantage of Europe's food sources, habitats and lack of predators for grey squirrels.

I am really poor at butterfly identification so have sought out a little assistance from my pal Bryan. Seemingly the Large White and Small White are extremely similar with the prime differentiator being their size. Bryan's belief even though he doesn't have any real scale here is that as this is a Small White.
Thank you for your help Bryan.
The Kuranda tree frog aka Myola tree frog (Litoria myola) is only known from a handful of rainforest creeks in the vicinity of Myola and Kuranda. They look extremely similar to the sympatric Litoria serrata, but can be differentiated by listening to their calls
IUCN: Critically Endangered
Location: Myola, Far North Queensland, Australia
This bird is often confused with the moorhen. However, it is easily differentiated by its more massive size, its white beak that is prolonged by a white patch on its forehead, its uniformly black plumage, and its shorter greenish legs with large bluish webbed toes with a very particular morphology.

Symphytum officinale is a perennial flowering plant in the family Boraginaceae. Along with thirty four other species of Symphytum, it is known as comfrey. To differentiate it from other members of the genus Symphytum, this species is known as common comfrey or true comfrey. Other English names include Quaker comfrey, cultivated comfrey, boneset, knitbone, consound, and slippery-root. It is native to Europe, growing in damp, grassy places. It is locally frequent throughout Ireland and Britain on river banks and ditches. It occurs elsewhere, including North America, as an introduced species and sometimes a weed. The flowers are mostly visited by bumblebees, Internal or long-term topical use of comfrey is discouraged due to its strong potential to cause liver toxicity.

This is the boyhood home of Lyndon Baines Johnson, 36th President of the United States. This view shows the west front porch of the home. Behind the porch on the right is the bedroom that the future president shared with his brother.
The house was built in 1901 by W.C. Russell, sheriff of Blanco County. In 1913, Sam Ealy Johnson, Jr. paid $2,925 for the house and the surrounding 1.75 acres. During the presidential years, the home was used as a community center and public tours were offered. In December of 1969, Congress designated this home as part of Lyndon B. Johnson National Historic Site. In the early 1970s, the National Park Service restored the home to its appearance during the mid-1920s, the teenage years of Lyndon B. Johnson.
The architectural style of the house is Folk Victorian, an architectural style employed for some homes in the United States between 1870 and 1910. Folk Victorian homes are relatively plain in its construction but embellished with decorative trim. Folk Victorian houses were built more commonly built for the middle class than the upper class. The style differentiates itself from other subsets of Victorian architecture (such as Queen Anne) by being less elaborate and having more regular floor plans.
Lyndon B. Johnson (1908-1973), also called LBJ, served as the 36th president of the United States from 1963-1969. A moderate Democrat and vigorous majority leader in the United States Senate, Johnson was elected vice president in 1960 and acceded to the presidency in 1963 upon the assassination of President John F. Kennedy. During his administration he signed into law the Civil Rights Act (1964), the most comprehensive civil rights legislation since the Reconstruction era, initiated major social service programs, and bore the brunt of national opposition to his vast expansion of American involvement in the Vietnam War.
Johnson City is the seat of Blanco County. The city was founded in 1879 by James Polk Johnson, uncle of Lyndon Johnson. Johnson City is located 47 miles (76 km) east of Austin, where the LBJ Presidential Library is located on main campus of the University of Texas.
Clicked while on the hunt for fish at the famous Ranganathittu Bird Sanctuary. Like most other Pelicans the Spot-billed Pelican catches fish in its huge bill pouch while swimming at the surface as seen here. This bird is a member of the Pelican family that breeds in southern Asia from southern Iran across India east to Indonesia. Easy to differentiate from other Pelicans in the same region at short range as they are smaller and also due to the spots on the upper mandible after which they are named. The species is found to breed only in peninsular India, Sri Lanka and in Cambodia. A few birds from India are known to winter in the Gangetic plains. Over the years due to habitat loss and human disturbance, their numbers have declined in Southeast Asia and are now considered as extinct in parts of China and Philippines, where the species was once abundant in the early 1900s. Though the populations in southern India are thought to be on the rise.

I am a replicant. The world has finally achieved that precious objective, creating androids in their image and likeness to make them slaves, but through that they have lost the most precious thing. They are known as "replicants" and today the world is full of them. Artificial humans with identical appearance to humans but with increased senses and abilities, we can think, feel, bleed and dream, but we were only created to obey and follow orders. Do androids dream of electric sheep?
But what is it that differentiates them from you? Like machines, humans have electrical connections that spin their thoughts. What makes them human then, the flesh? The bones? The entrails? Or is that inexplicable, that as a result of a point of processes it gives us what we call "soul".
Now you can't tell who really is a human. Rumor has it that there is a child of a replicating mother, they call it a miracle. Others call it a nightmare, only some know, people don't want the truth to be revealed because the world would lose its mind. They fear that machines are no longer so different from humans, it could be anyone, it could be me. I will give my life to find that child, dying for the right cause is the most humane thing we can do. And so machines will now be more human than humans.
I have always wanted to have a life of my own without following orders, with someone by my side who makes me feel loved and have an identity that does not contain numbers or a record under my eye with the date of my creation. I think we were all designed for something and we all have a destiny, maybe that's what having a life is all about.
But life does not mean living, I want to live. People are lying, selfish and stupid beings, they live all the time in fear, that also makes them slaves. We are almost more human than you, in everything except our perfect right eye.
I have seen things that you could never believe, all those moments will be lost in time. Like tears in the rain.

The High Rhine (German: Hochrhein) is the name used for the part of the Rhine that flows westbound from Lake Constance to Basel.
The High Rhine begins at the out flow of the Rhine from the Untersee in Stein am Rhein and turns into the Upper Rhine in Basel. In contrast to the Alpine Rhine and Upper Rhine, the High Rhine flows mostly to the west.
The term High Rhine was introduced by scientists in the 19th century. Above all geologists tried to differentiate the High Rhine linguistically from the Upper Rhine. Until the 19th century, it was also known as the "Badisch-Swiss Rhine".[1]

Three Pelicans with a Mugger crocodile for company. These birds are difficult to differentiate from other pelicans in the region except for the unmistakable spots on the upper mandible from which they derive their name. The lack of bright colours and the greyer plumage are distinctive. A strange thing is that these birds tend to nest close to human habitations and some villages with nesting colonies have become popular tourist attractions. Though the numbers of these birds have declined and many populations in Southeast Asia are now extinct, the populations in southern India are thought to be on the rise enabling their status to be changed from vulnerable to near threatened in the 2007.

Wikipedia: The lesser whistling duck (Dendrocygna javanica), also known as Indian whistling duck or lesser whistling teal, is a species of whistling duck that breeds in the Indian subcontinent and Southeast Asia. They are nocturnal feeders that during the day may be found in flocks around lakes and wet paddy fields. They can perch on trees and sometimes build their nest in the hollow of a tree. This brown and long-necked duck has broad wings that are visible in flight and produces a loud two-note wheezy call. It has a chestnut rump, differentiating it from its larger relative, the fulvous whistling duck, which has a creamy white rump.
A target bird of mine for many years and one that I couldn't differentiate with the Common Woodshrike for a while. After a couple of sightings, now I am confident about the id. These are a member of the Flycatcher-Shrikes / Woodshrike and found widely across South Asia and much of South East Asia.
They are about 20-23 cms and often found inside the canopy, hunting insects with their thick beaks. Their diet primarily includes Grasshoppers, beetles, moths, Cicadas, Mantids and spiders, but a few times, I have seen them feed on berries and other plant matter.
These are resident birds and non-migratory. The forest we visited had a healthy number of these. Two years, when I sighted it there, there was a hunting party of around 6-8 Woodshrikes that were hunting insects a large tree. They moved a couple of trees together and disappeared from view. - that was a memorable moment for me after seeing so many of them for the first time.
