Pine Warbler

This is the only montane laughingthrush in its range and hence unmistakable. It has dull olive-brown upperparts, a grey-streaked white breast, and a rufous-chestnut lower breast and belly. The most striking characteristic is the white eyebrow, flaring in front of the eye over a dark eye-line. Found in stunted montane forests, tea estates, and wooded second growth, in pairs or noisy flocks, producing a melodious “pe-kee-ke” song and several other chatters intermingled with musical notes. Heard more often than seen; its songs and calls are usually the first indication of its presence. 

Plump chickenlike bird found in rocky tundra and alpine summits. Plumage changes strikingly throughout the year. In winter, both sexes are pure white with black outer tail feathers. As summer progresses, male develops cold grayish-brown feathers on head, neck, and back; generally quite splotchy looking. Summer female is paler golden-brown with intricate black and white markings. Female nearly identical to Willow Ptarmigan; look for slightly smaller bill. Summer male Willow and Rock Ptarmigans can be separated by the colder grayish plumage on Rock Ptarmigan and in winter by the distinctive black eyeline on Rock Ptarmigan. Also note habitat differences. Best distinguished from White-tailed Ptarmigan by black outer tail feathers. Vocalizations include guttural groaning and clucking notes.

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.
