Little Green Sunbird

Large sparrowlike bird; entirely olive with contrasting gray head and black face. Range does not overlap with other similar-looking sparrows and brushfinches. Often found in pairs or small family groups, usually scratching through leaf litter or low in a tangle in the forest understory. Loud song often heard at dawn. Sexes alike.

Gray bird with a yellow bill and legs found in arid areas of northwestern Peru. Despite its name, it is currently placed in the tanager family, though its thick, stubby bill does give it a finch-like look. Young birds have less black on the face than adults, and paler bill and legs. Similar to Band-tailed Sierra Finch, but has a stubbier bill and lacks brown streaks on the back. Most common in deserts with scattered small trees, though also occasionally found in denser forest.

Striking large shearwater with distinctive dark "M" pattern on upperwings. Also note crisp dark cap and clean white underwings and belly. Looks silvery-gray above when fresh, but worn birds can be more brownish. Graceful flight style. Usually easily separated from other shearwaters by wing pattern. Breeds on islands off New Zealand; ranges across the Pacific during nonbreeding season; uncommon off the west coast of the U.S. in fall. Rarely seen from land, prefers to stay offshore. Found singly or in flocks with other shearwaters.
