HAEMATOPUS PALLIATUS PDF

Juvenile and adult. Often forages by walking in shallow water, searching for food by sight. The birds have two methods of opening the shells of bivalves. In one, finding a mussel with its shell slightly open, the oystercatcher quickly jabs its bill into the opening, cutting the muscles and then cleaning out the contents. In the other method, the bird simply hammers on the shell to break it open.

The American oystercatcher Haematopus palliatus , occasionally called the American pied oystercatcher , is a member of family Haematopodidae. Originally called the "sea pie", it was renamed in when naturalist Mark Catesby observed the bird eating oysters. The American oystercatcher has distinctive black and white plumage and a long, bright orange beak. The head and breast are black and the back, wings and tail greyish-black. The underparts are white, as are feathers on the inner part of the wing which become visible during flight.

The irises are yellow and the eyes have orange orbital rings. The legs are pink. The American oystercatcher is found on the Atlantic coast of North America from New England to northern Florida , where it is also found on the Gulf coast , and south to Brazil , Uruguay and Argentina. After receiving protection under the Migratory Bird Treaty Act , their range extended northward to re-occupy historical habitat in New England.

During the breeding season, these birds are found along the Atlantic and Gulf Coasts and from Massachusetts south to Argentina and Chile. During the breeding season, the American oystercatcher can be found in coastal habitats including sand or shell beaches, dunes, salt marshes, marsh islands, mudflats, and dredge spoil islands made of sand or gravel. They are also found on shellfish beaches at this time.

Oystercatchers are closely tied to coastal habitats. They nest on beaches on coastal islands and feed on marine invertebrates. The large, heavy beak is used to pry open bivalve mollusks. Oystercatchers raise a clutch of two or three eggs. The American oystercatcher feeds almost exclusively on shellfish and other marine invertebrates. As they walk across a shellfish bed, they look for a mollusk with a partially opened shell. When they find one, they jab their bill into the shell and sever the muscle that causes the shell to clamp shut.

A strong, tightly rooted mollusk can hold the bird in place until the tide comes in. American oystercatchers first breed when they're years old.

When courting, the birds will walk together and make a single piping note. This progresses to leaning towards each other, extending and lowering the neck, and running alongside each other while calling. American oystercatchers breed between April and July. Each egg is 2. The eggs are gray and speckled with dark brown. Although the eggs are well camouflaged, they are vulnerable to predation by raccoons, coyotes, skunks, gulls, crows, rats, and foxes.

Both parents will alternate incubating the eggs for 25 to 27 days. When born, the chicks are covered in tan down [8] and can run within 2 hours of hatching. Historically, the American oystercatcher was hunted to near extinction in the 19th century for plumage and eggs. The reasons given are that the bird has a very wide range and that the total number of individuals is believed to be stable, and actually increasing in the case of the United States.

American oystercatcher

American oystercatchers Haematopus palliates have a far spreading range across the world, they have been found in the United States, Cuba, Brazil, and Mexico. Among the several other oystercatcher species, American oystercatchers are the only species native to the Atlantic Coast of North America. Along the Atlantic Coast, their breeding range spans between Massachusetts and Florida. American oystercatchers can be found year-round throughout parts of the Caribbean and the Gulf Coast. In South America, this species occurs as far south as Chile and Argentina; they are also found locally on both coasts of Mexico and Central America, breeding as far north as Baja, California. There is still relatively little known about the routes these birds take when traveling from wintering grounds to breeding spots. Elphick, et al.
