American Oystercatchers feed on crustaceans and molluscs and are also able to open crab shells with their strong beaks.

American Oystercatchers patrol the beaches for food and are somewhat approachable, they actually come close to the tourists. Chicks are often seen trying to get their own food when just a few weeks old. This behavior is typical of shorebirds who are less dependant on their parents than seabirds.

American Oystercatchers are listed as a species of concern in several states because of low and declining populations, and threats to coastal habitats.

Threats include development and recreational use of nesting beaches.

These handsome looking countershaded waders use their bright beak to stab a bivalve between the shells of many moluscs and slice the strong adductor muscles to get at the meat inside.
