About American Oystercatchers

The American Oystercatcher is a large boldly-patterned bird native to North America. It can also be referred to as the American Pied Oystercatcher but was originally called the Sea Pie. They breed along the Atlantic and Gulf Coasts of North America. Their numbers may have seriously declined in the 19th century but have since recovered in the 20th century. The decline was due to disturbance of their beach habitats but has since stabilized.

They can be found on the Atlantic Coast of North America spanning from New England to northern Florida. The bird has also been spotted in Argentina, Uruguay, and Brazil.

American Oystercatcher Behavior

Bird watchers cannot miss them in coastal habitats as that is the predominant point to catch their food. Nesting happens on beaches on coastal islands. The beak is adapted to opening bivalves.

American Oystercatcher Diet

These birds derive their namesake from their diet, and almost solely consume saltwater bivalve mollusks, including many species of clams, mussels, and oysters. They also consume limpets, jellyfish, starfish, sea urchins, marine worms, and a few crustaceans to a lesser degree. Their general way of finding is prey is through the use of their bills. They walk across shellfish beds and look for mollusks with partially opened shells that they can jab their bills into. This is done in order to sever the muscles that cause the shells to clamp shut and can thus get dangerous sometimes when the shells clamp down on their bills. Tightly rooted shells may hold a bird in place until the tides change, drowning the birds. They may also forage loose shellfish out of the water by hammering at shells or by probing in the sand. For bivalves like razor clams, mole crabs, and polychaete words, they probe into the substrate and capture their prey by touch. As a result, tidal conditions heavily influence when these birds forage. They forage the most heavily during falling tides.

It feeds exclusively on shellfish and other marine invertebrates found on the eastern coast of North America. The bird is accustomed to oysters hence its name the American Oystercatcher. They also feed on clams, limpets, crabs, starfish, sea urchins, and mussels.

American Oystercatcher Habitat

American Oystercatchers are found only in intertidal areas and in the adjacent beaches. They are especially abundant on barrier islands with few to no predators. Within such coastal habitats, they generally prefer sandy and shelly beaches for nesting but may also nest on sandy spots in saltmarshes or on mats of dead vegetation. Artificial beaches like dredge-spoil islands made of sand or gravel also attract these birds for nesting and roosting. During storms, they take shelter in open habitats in agricultural fields in surrounding areas.

You will find them strictly in coastal habitats which include coastal beaches and tidal flats. The American Oystercatcher can also be found in areas with extensive sandy beaches, salt marsh, and tidal mudflats. The key is having access to seafood supplies.

Range and Migration

American Oystercatchers have boldly patterned shorebirds found along the Atlantic coasts of the United States, Mexico, and the Caribbean. They are also found along the pacific coasts of the Baja Peninsula, Mexico, and Central America. These birds are generally residents of their breeding grounds and rarely migrate, except for short distances that the northernmost populations may undertake during winter. They are abundantly found in flocks from Massachusetts to the Gulf of Mexico.

American Oystercatcher Lifecycle

Females can lay up to 4 eggs which they keep incubated for 24-28 days when they hatch. The young ones are fed with both parents for about 2 months and would sometimes attempt to forage on their own. The young take the first flight at 5 weeks. An adult American Oystercatcher may reach the age of 10 years and above.

Nesting

Nesting sites are selected by the females in vegetation on barrier beaches, usually within or behind dunes. They can also be found nesting in shelly islands, dredge-spoil islands, or on high marshes. The nesting sites typically feature dune vegetation such as sea oats and beach grass and can be often found among short bushes and shrubbery. In artificial beaches or in urban areas, pairs have been found nesting on gravel rooftops or on rocky, artificial islands. These nests are generally simple depressions in the sand with no lining at all. A female has 1–2 broods each season and can lay between 2–4 eggs in a clutch.
