1384 WILSON'S SNIPE. Gallinago delicata
USA 39
Wilson's snipe is a small, stocky shorebird. They breed in marshes, bogs, tundra and wet meadows in Canada and the northern United States and on the Chukchi Peninsula, Russia. They are year-round residents on the U.S. Pacific coast. The eastern population migrates to the southern United States, the Caribbean, and to northern South America. It may be that climate change causes these birds to move to their breeding range earlier and leave later than 100 years ago.
They forage in soft mud, probing or picking up food by sight and eating insects, earthworms, and plant material. Well-camouflaged, they are usually shy and conceal themselves close to ground vegetation, flushing only when approached closely. They fly off in a series of aerial zig-zags to confuse predators.
537* SANDERLING Calidris alba
USA 38
The sanderling is a small wading bird. It is a circumpolar Arctic breeder, and is a long-distance migrant, wintering south to South America, South Europe, Africa, and Australia. It is highly gregarious in winter, sometimes forming large flocks on coastal mudflats or sandy beaches.
Sanderlings feed on invertebrate prey buried in the sand in the upper intertidal zone. In North America, this diet largely consists of the isopods Excirolana linguifrons, Excirolana kincaidii, and the mole crab, Emerita analoga. When the tide is out, these crustaceans live in burrows some way beneath the surface. When the tide comes in, they move into the upper layers of sand and feed on the plankton and detritus that washes over them with each wave. They then burrow rapidly down again as the water retreats. They leave no marks on the surface, so the sanderlings hunt for them by plunging their beaks into the sand at random, consuming whatever they find.
USA 37
The spotted sandpiper is a small shorebird. Together with its sister species the common sandpiper (A. hypoleucos), it makes up the genus Actitis. They replace each other geographically; stray birds may settle down with breeders of the other species and hybridize. Spotted sandpipers are a philopatric species.[8] Their breeding habitat is near fresh water across most of Canada and the United States. They migrate to the southern United States, the Caribbean, and South America, and are very rare vagrants to western Europe. These are not gregarious birds and are seldom seen in flocks. Spotted sandpipers are the most widespread species of their kind in North America due to their high breeding rates and their ability to adapt to various environmental pressures
These birds forage on the ground or in water, picking up food by sight. They may also catch insects in flight. They eat insects (such as flies, beetles, grasshoppers, mayflies, midges, crickets and caterpillars), crustaceans and other invertebrates (such as spiders, snails, other molluscs, and worms), as well as small fish and carrion. As they forage, they can be recognized by their constant nodding and teetering.
1382 GREATER YELLOWLEGS Tringa melanoleuca
USA 36
The greater yellowlegs is a large shorebird in the family Scolopacidae. It breeds in central Canada and southern Alaska and winters in southern North America, Central America, the West Indies and South America. Their breeding habitat is bogs and marshes in the boreal forest region of Canada and Alaska. They migrate to the Atlantic and Pacific coasts of the United States, the Caribbean, and south to South America. They are very rare vagrants to western Europe. They nest on the ground, usually in well-hidden locations near water. The three to four eggs average.The incubation period is 23 days. The young leave the nest within 24 hours of hatching and then leave the vicinity of the nest within two days.
These birds forage in shallow water, sometimes using their bills to stir up the water. They mainly eat insects and small fish, as well as crustaceans, marine worms, frogs, seeds and berries.
562* BLACK-BELLIED PLOVER Pluvialis squatarola
USA. 34
The grey plover or black-bellied plover is a large plover breeding in Arctic regions. It is a long-distance migrant, with a nearly worldwide coastal distribution when not breeding. They forage for food on beaches and tidal flats, usually by sight. The food consists of small molluscs, polychaete worms, crustaceans, and insects. It is less gregarious than the other Pluvialis species, not forming dense feeding flocks, instead feeding widely dispersed over beaches, with birds well spaced apart. They will however form dense flocks on high tide roosts.
1381 SANDHILL CRANE Antigone canadensis
USA 33
The sandhill crane is a species of large crane of North America and extreme northeastern Siberia. The common name of this bird refers to their habitat such as the Platte River, on the edge of Nebraska's Sandhills on the American Great Plains. Sandhill cranes are known to frequent the edges of bodies of water. The central Platte River valley in Nebraska is the most important stopover area for the nominotypical subspecies, the lesser sandhill crane (A. c. canadensis), with up to 450,000 of these birds migrating through annually.
1380 LIMPKIN Aramus guarauna
USA 32
The limpkin, also called carrao, courlan, and crying bird, is a large wading bird related to rails and cranes, and the only extant species in the family Aramidae. It is found mostly in wetlands in warm parts of the Americas, from Florida to northern Argentina, but has been spotted as far north as Wisconsin and Southern Ontario. It feeds on molluscs, with the diet dominated by apple snails of the genus Pomacea. Its name derives from its seeming limp when it walks.
1379 AMERICAN COOT Fulica americana
USA. 31
The American coot, also known as a mud hen or pouldeau, is a bird of the family Rallidae. Though commonly mistaken for ducks, American coots are only distantly related to ducks, belonging to a separate order. Unlike the webbed feet of ducks, coots have broad, lobed scales on their lower legs and toes that fold back with each step to facilitate walking on dry land.Coots live near water, typically inhabiting wetlands and open water bodies in North America. Groups of coots are called covers or rafts. The oldest known coot lived to be 22 years old.
The American coot is a migratory bird that occupies most of North America. It lives in the Pacific and southwestern United States and Mexico year-round and occupies more northeastern regions during the summer breeding season. In the winter they can be found as far south as Panama. American coots eat primarily algae and other aquatic plants but also animals (both vertebrates and invertebrates) when available.
The American coot is closely related to the Eurasian coot (Fulica atra), which occupies the same ecological niche in Eurasia and Australia as the American coot does in North America. Eurasian coots can be distinguished from this species by the absence of a red callus above the bird's frontal shield.
1378 SORA Porzana carolina
USA 30
The sora, sora rail or Carolina crake is a small waterbird of the rail family Rallidae, sometimes also referred to as the sora rail or sora crake, that occurs throughout much of North America. The genus name Porzana is derived from Venetian terms for small rails, and the specific carolina refers to the Carolina Colony. The common name "Sora" is probably taken from a Native American language.
The sora's breeding habitat is marshes throughout much of North America. They nest in a well-concealed location in dense vegetation. The female usually lays 10 to 12 eggs, sometimes as many as 18, in a cup built from marsh vegetation. The eggs do not all hatch together. Both parents incubate and feed the young, who leave the nest soon after they hatch and are able to fly within a month.
They migrate to the southern United States and northern South America. Soras forage while walking or swimming. They are omnivores, eating seeds, insects and snails. Although soras are more often heard than seen, they are sometimes seen walking near open water. They are fairly common, despite a decrease in suitable habitat in recent times. The call is a slow whistled ker-whee, or a descending whinny.
1377 RED-SHOLUDERED HAWK Buteo lineatus
USA 29
The red-shouldered hawk is a medium-sized buteo. Its breeding range spans eastern North America and along the coast of California and northern to northeastern-central Mexico. It is a permanent resident throughout most of its range, though northern birds do migrate, mostly to central Mexico. The main conservation threat to the widespread species is deforestation.

USA 27
The northern harrier, also known as the marsh hawk or ring-tailed hawk, is a bird of prey. It breeds throughout the northern parts of the northern hemisphere in Canada and the northernmost USA. The northern harrier migrates south in winter, with breeding birds in Canada and northern Great Plains of the U.S. moving to the American south, Mexico, and Central America. In the midwestern, mountain west, and north Atlantic states of the U.S., they may be present all year. This bird inhabits prairies, open areas, and marshes.
1375 BALD EAGLE Haliaeetus leucocephalus
USA 26
The bald eagle is a bird of prey found in North America. A sea eagle, it has two known subspecies and forms a species pair with the white-tailed eagle (Haliaeetus albicilla), which occupies the same niche as the bald eagle in the Palearctic. Its range includes most of Canada and Alaska, all of the contiguous United States, and northern Mexico. It is found near large bodies of open water with an abundant food supply and old-growth trees for nesting.
The bald eagle is an opportunistic feeder which subsists mainly on fish, which it swoops down upon and snatches from the water with its talons. It builds the largest nest of any North American bird and the largest tree nests ever recorded for any animal species, up to 4 m (13 ft) deep, 2.5 m (8.2 ft) wide, and 1 metric ton (1.1 short tons) in weight. Sexual maturity is attained at the age of four to five years.
