Yellow-green Tyrannulet

A little-known small drab bird of lowland and foothill forest. Gray-brown above, darker in the wing, with a gray-brown chest blending to a white belly and a small white throat patch. Note the bicolored bill, black above and orange below. Similar to Furtive Flycatcher, but slightly larger, with an orange lower bill, no rufous outer tail feathers, and no black band on the end of the tail. Song consists of very high-pitched short phrases repeated at intervals.

Medium-sized ovenbird with a long spiky tail. Cinnamon-brown above, paler below, with a darker cap and wings. Note the freckled breast and yellow eyes. Usually found near water, in marshes, gallery forests, and scrub, where it forages on the ground or in the understory. Builds large thorny nests that do not hang from trees, unlike other thornbirds.

Small, short-legged coastal goose; distinctive black head and neck with small white necklace. Some variation in belly and flank coloration across subspecies. "Black Brant," mainly of western North America and eastern Asia, is darkest, with contrasting white flanks. Breeds on tundra in the high Arctic; winters in saltmarshes, rocky coastlines, sheltered bays, and beaches. Typically uncommon to rare inland. Almost always seen in flocks, only rarely mixing with other geese species.
