About These Birds
Red Knot
Red Knot: 23–26 cm, robust sandpiper with brick-red breeding plumage; one of the most remarkable long-distance migrants, travelling up to 15,000 km between Arctic breeding grounds and South American or Australian wintering shores. NT. Threatened by horseshoe crab egg depletion at Delaware Bay staging sites. Key refuelling stops critical.
American Woodcock
American Woodcock: 25–31 cm, rotund crepuscular wader with cryptic dead-leaf plumage, large eyes set high on the head, and an extremely long flexible bill for probing earthworms. Inhabits moist woodland and shrubby margins in eastern North America; winters in southern US. Famous for spiralling courtship 'sky dance.' Migratory.
