Bright orange bill specialized to crack bivalves. Delivers messages with a knife already drawn.
- Populasi
- ~61,000 mature individuals (~8,000 North American + ~53,000 South American; 50,000-99,999)
- Habitat
- Coastal intertidal environments — sandy and shelly beaches, dunes, salt marshes, marsh islands, tidal mudflats, and dredge-spoil islands; forages on exposed mud/sand flats at low tide and roosts/nests above the high-tide line.
- Fakta menarik
- The American Oystercatcher's long, blade-like red-orange bill is a specialized tool that it uses to either snip shut a bivalve's adductor muscle before the shell can close, or hammer straight through the shell to reach the meat inside.
- Sebaran
- Atlantic and Gulf coasts of North America from Massachusetts to Florida and Texas, the Caribbean, and south through Central America to Brazil, Uruguay, and Argentina; also Pacific coasts of Baja California, Mexico, Central America, Peru, and Chile. Northernmost breeding populations (US Atlantic/Canada coast) are migratory; southern populations are largely resident. Occurs across 40+ countries/territories.
- Makanan
- Almost exclusively marine bivalves and other intertidal invertebrates — oysters, mussels, clams, limpets — plus marine worms, crabs, sea urchins, starfish, and jellyfish; uses its long, laterally flattened bill either to snip the adductor muscle of slightly opened shells or to hammer shells open.
