There are several species of Eastern migratory birds. The American Anhinga, for instance, is a waterbird and is sometimes referred to as the Snakebird. The Anhinga is found primarily in Southeastern United States occurring in several Texas river bottoms. These birds breed along the Atlantic and Gulf coasts from North Carolina to Texas, in Florida, and in the Mississippi Valley north to Southern Missouri and Kentucky. In the month of August, large flocks of Anhingas start their migration southward along rivers to the upland side of the Gulf Coast north to South Carolina. They primarily use the Mississippi Flyaway route to migrate. Their diet primarily consists of fish and amphibians.
Another North American Eastern migratory bird is the Razorbill. This bird's habitat includes the rocky shores, cliffs and islands of the eastern part of the United States, extending as far as Maine. The Razorbill migrates offshore and tends to move south, starting from the Grand Banks of Newfoundland to the state of New England. Its diet consists mainly of fish, however, the Razorbill may consume crustaceans as well. Razorbills generally forage for their food by going underwater and lay their eggs on rocks or on the ground.
The Iceland Gull is another migratory bird that breeds on the Southern Baffin Island, Northwestern Quebec and on the islands of Hudson Bay. It migrates south to New Jersey during winters and can be found on rocky coasts, cliffs, harbors and landfills. The birds are considered omnivores and eat a diet consisting of fish, eggs and mollusks. They generally pick their prey while flying, from the surface of the water or sometimes from beneath it. Iceland Gulls are considered waterbirds and are commonly found along the coasts of the Eastern United States.
