American Oystercatcher — size comparison — facts and sources
The American oystercatcher feeds on beaches, islands and coastal shallows. It opens bivalves with a strong red bill, inserting it into partly open shells to sever the closing muscle. Some birds instead hammer shells.
Adults teach young their chosen technique. Feeding intensifies at low tide when molluscs remain partly submerged with open shells.
