White-cheeked Cotinga

Large, dark sea duck. Breeding males have a colorful bill and white patches on the nape and forehead. Females and first-year males are dark brown with white patches on the cheek and face. Note large, thick-based bill to help separate from female White-winged Scoter. Breeds on lakes and ponds in northern Canada and Alaska; winters in flocks in harbors, bays, and other coastal waters, where dives for mussels and other aquatic invertebrates. Uncommon to rare inland, especially in migration. Frequently mixes with other sea duck species, especially eiders and scoters.

Medium-sized songbird of woodlands, neighborhoods, and parks. Male grayish brown with black head and wings, faintly orange flanks, and a dark-tipped yellow bill. Female similar but lacks the black head, has much paler orange on the flanks, and is an overall brownish tone. Male similar to Japanese Grosbeak, which has less black on the head, no orange on the flanks, and lacks the dark tip to the bill of most adult male Yellow-billed Grosbeaks. Often detected as it gives a hard "jik!" while flying overhead.

Tiny, plump flycatcher found in the understory of subtropical and temperate cloud forest in the Andes. Not likely to be confused. Bright rufous head, wings, and tail contrast with olive back and breast. Belly slightly paler yellow. Sexes similar. Flits around the understory in singles or pairs, usually within forest. Best detected by its bill snaps or descending rattle call.
