One of the many birds we encountered on the Superior CBC in and around Oak Flat Campgrounds, near Superior, AZ on 12/26/11. This was a new lifer for me.
The golden eagle (Aquila chrysaetos) is one of the best-known birds of prey in the Northern Hemisphere. It is the most widely distributed species of eagle. Like all eagles, it belongs to the family Accipitridae. These birds are dark brown, with lighter golden-brown plumage on their napes. Immature eagles of this species typically have white on the tail and often have white markings on the wings. Golden eagles use their agility and speed combined with powerful feet and massive, sharp talons to snatch up a variety of prey (mainly hares, rabbits, marmots and other ground squirrels).
Golden eagles maintain home ranges or territories that may be as large as 200 km2 (77 sq mi). They build large nests in high places (mainly cliffs) to which they may return for several breeding years. Most breeding activities take place in the spring; they are monogamous and may remain together for several years or possibly for life. Females lay up to four eggs, and then incubate them for six weeks. Typically, one or two young survive to fledge in about three months. These juvenile golden eagles usually attain full independence in the fall, after which they wander widely until establishing a territory for themselves in four to five years.
Once widespread across the Holarctic, it has disappeared from many areas which are now more heavily populated by humans. Despite being extirpated from or uncommon in some its former range, the species is still fairly ubiquitous, being present in sizeable stretches of Eurasia, North America, and parts of North Africa. It is the largest and least populous of the five species of true accipitrid to occur as a breeding species in both the Palearctic and the Nearctic.
For centuries, this species has been one of the most highly regarded birds used in falconry, with the Eurasian subspecies having been used to hunt and kill prey such as gray wolves (Canis lupus) in some native communities. Due to its hunting prowess, the golden eagle is regarded with great mystic reverence in some ancient, tribal cultures. The golden eagle is one of the most extensively studied species of raptor in the world in some parts of its range, such as the Western United States and the Western Palearctic.
Come on, birders, help me out: red-headed something or other does laps over Lake Sabula, IA on a very warm afternoon, which featured swimmers on this April 15.
A grebe is a member of the order Podicipediformes and the only type of bird associated with this order. Grebes are a widely distributed order of freshwater diving birds, some of which visit the sea when migrating and in winter.
was waiting for a bird to eventually land on this small garden statue,and along came a great tit,i only used a 50mm lens for this shot,so who says you need a long telephoto lens for bird photography? lol
Common Crane
The common crane (Grus grus), also known as the Eurasian crane, is a bird of the family Gruidae, the cranes.
A medium-sized species, it is the only crane commonly found in Europe besides the demoiselle crane (Anthropoides virgo). Along with the sandhill (Grus canadensis) and demoiselle cranes and the brolga (Grus rubicunda), it is one of only four crane species not currently classified as threatened with extinction or conservation dependent on the species level.
The common crane is a large, stately bird and a medium-sized crane. It is 100–130 cm (39–51 in) long with a 180–240 cm (71–94 in) wingspan. The body weight can range from 3 to 6.1 kg (6.6 to 13.4 lb), with the nominate subspecies averaging around 5.4 kg (12 lb) and the eastern subspecies (G. g. lilfordi) averaging 4.6 kg (10 lb). Among standard measurements, the wing chord is 50.7–60.8 cm (20.0–23.9 in) long, the tarsus is 20.1–25.2 cm (7.9–9.9 in) and the exposed culmen is 9.5–11.6 cm (3.7–4.6 in).
This species is slate-grey overall. The forehead and lores are blackish with a bare red crown and a white streak extending from behind the eyes to the upper back. The overall colour is darkest on the back and rump and palest on the breast and wings. The primaries, the tips of secondaries, the alula, the tip of the tail, and the edges of upper tail coverts are all black and the greater coverts droop into explosive plumes. This combination of colouration ultimately distinguishes it from similar species in Asia, like the hooded (G. monacha) and black-necked cranes (G. nigricollis). The juvenile has yellowish-brown tips to its body feathers and lacks the drooping wing feathers and the bright neck pattern of the adult, and has a fully feathered crown. Every two years, before migration, the adult common crane undergoes a complete moult, remaining flightless for six weeks, until the new feathers grow.
It has a loud trumpeting call, given in flight and display. The call is piercing and can be heard from a considerable distance. It has a dancing display, leaping with wings uplifted.
This species is found in the northern parts of Europe and Asia. Formerly the species was spread as far west as Ireland, but about 200 years ago, it became extinct there. However, it has since started to return to Ireland naturally and there are now plans to help it return to Ireland on a greater scale. The common crane is an uncommon breeder in southern Europe, smaller numbers breeding in Greece, former-Yugoslavia, Romania, Denmark and Germany. Larger breeding populations can be found in Scandinavia, especially Finland and Sweden. The heart of the breeding population for the species is in Russia, however, where possibly up to 100,000 cranes of this species can be found seasonally. In Russia, it is distributed as a breeder from the Ukraine region to the Chukchi Peninsula. The breeding population extends as far south as Manchuria but almost the entire Asian breeding population is restricted to Russia.
The species is a long distance migrant predominantly wintering in northern Africa. Autumn migration is from August to October and spring migration is in March through May. Important staging areas occur anywhere from Sweden and Germany to China (with a large one around the Caspian Sea) and many thousand cranes can be seen in one day in the Autumn. Some birds winter in southern Europe, including Portugal, Spain and France. Most eastern common cranes winter in the river valleys of Sudan, Ethiopia, Tunisia and Eritrea with smaller numbers in Turkey, northern Israel, Iraq and parts of Iran. The third major wintering region is in the northern half of Indian subcontinent, including Pakistan. Minimal wintering also occurs in Burma, Vietnam and Thailand. Lastly, they winter in eastern China, where they are often the most common crane (outnumbering black-necked cranes ten-to-one). Migrating flocks fly in a "V" formation.
It is a rare visitor to Japan and Korea, mostly blown over from the Chinese wintering population, and is a rare vagrant to western North America, where birds are occasionally seen with flocks of migrating sandhill cranes.
In Europe, the common crane predominantly breeds in boreal and taiga forest and mixed forests, from an elevation of sea-level to 2,200 m (7,200 ft). In northern climes, it breeds in treeless moors, on bogs, or on dwarf heather habitats, usually where small lakes or pools are also found. In Sweden, breeders are usually found in small, swampy openings amongst pine forests, while in Germany, marshy wetlands are used. Breeding habitat used in Russia are similar, though they can be found nesting in less likely habitat such as steppe and even semi-desert, so long as water is near. Primarily, the largest number of common cranes are found breeding in wooded swamps, bogs and wetlands and seem to require quiet, peaceful environs with minimal human interference. They occur at low density as breeders even where common, typically ranging from 1 to 5 pairs per 100 km2 (39 sq mi).
In winter, this species moves to flooded areas, shallow sheltered bays, and swampy meadows. During the flightless moulting period there is a need for shallow waters or high reed cover for concealment. Later, after the migration period, the birds winter regularly in open country, often on cultivated lands and sometimes also in savanna-like areas, for example on the Iberian Peninsula.
The global population is 600,000 (2014 estimate) with the vast majority nesting in Russia and Scandinavia. In some areas the breeding population appears to be increasing, such as in Sweden, whereas on the fringes of its range, it is often becoming rare to non-existent. In Great Britain, the common crane became extirpated in the 17th century, but a tiny population now breeds again in the Norfolk Broads and is slowly increasing and a reintroduction has been underway since 2010 for the Somerset levels. In Ireland, it died out as a breeding species in the 18th century, but a flock of about 30 appeared in County Cork in November 2011, and a smaller flock a year later. It was additionally extirpated as a breeder from Austria around 1900, from Hungary by 1952 and from Spain by 1954. The recovering German breeding population of 8,000 pairs is still also a fraction of the size of the large numbers that once bred in the country. Poland has 15,000 breeding pairs, 50 pairs breed in the Czech Republic and 2009 was the first confirmed breeding in Slovakia.
The main threat to the species, and the primary reason for its decline in the Western Palearctic, comes from habitat loss and degradation, as a result of dam construction, urbanisation, agricultural expansion, and drainage of wetlands. Although it has adapted to human settlement in many areas, nest disturbance, continuing changes in land use, and collision with utility lines are still potential problems. Further threats may include persecution due to crop damage, pesticide poisoning, egg collection, and hunting. The common crane is one of the species to which the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA) applies.

When you sit in the food court area up in the middle of the boardwalk where a lot of the food concessions are, they have strung clear fishing line all across the open areas between the roofs of the buildings in order to discourage the seagulls from dive bombing unsuspecting diners. This tact seems to work pretty well, however there are a few smart ones that have figured out how to "walk in" from the sides of the boardwalk. This guy was busy walking under all the tables picking up dropped french fries.
