Pere David's Laughingthrush

Dark body with orange bare skin at the base of the bill. Breeding adults are all black. Immatures and nonbreeders have paler breast. Dives underwater to catch fish. Swims like a duck in between dives. Finds open perches to spread wings and dry feathers. Can be in large flocks or solo. Most widespread cormorant across U.S. and Canada; also most likely to be seen inland.

A massive vulture with a bullish, naked, square head, a bulky bluish-yellow beak, and wrinkled loose skin (lappets) on the face. Adults have a brown-and-white streaked chest and puffy white leggings, while immatures are all-brown. In flight, the very broad wings, white leggings, and small white lines at the front of the wing are diagnostic. Rare and declining but widespread in open country; found in drier areas than other vultures. Aggressive at kills, dominating proceedings and opening the carcass for other scavengers.

Very local and endangered small sparrow of highlands in central Mexico; endemic. Occurs in bunchgrass within areas of open pine woods; often rather elusive. Feeds on the ground in grassy areas and adjacent plowed fields, but sings from prominent grass stalks. Plumage looks much like Song Sparrow, with gray face, black-streaked breast and flanks, and rusty wings. Song Sparrow is larger and bulkier, with less extensive rusty in wings, and almost always lives in wetter habitats.
