Sclater's Tyrannulet

Distinctive, tiny, short-tailed waxbill. The underparts vary geographically from yellow to orange. The red rump is distinctive in flight. Found in wetlands, moist grasslands, and moist cultivation. Usually in small flocks. Call is a “svet” that is often repeated or given in chorus by a whole flock, especially in flight. Somewhat similar to Quailfinch but easily separated by yellow or orange underparts and by red rump.

Thickset, short-winged, pot-bellied gull. Adult has dark gray back and wings, intense pink legs, and an especially large white “crescent” (white tertial edges) near the wingtips when perched. Breeding adult white-headed; nonbreeding birds have variably heavy brown streaking on the head and upper breast. Takes four years for immatures to progress from mostly brown to fully white and gray adult plumage; intermediate plumages are often mottled and messy. Often looks rather frosty by the first winter; starts to develop a gray back and whitish eye in its second year. Primarily an Asian species, found in coastal regions from Japan and South Korea to Russia. Regularly occurs in western Alaska, but very rare elsewhere in North America.

Large, crow-sized bird, gray or black, with large black bill and yellow eye. In flight, white undertail, tail tip, and primary bases distinctive; some subspecies of Pied Currawong very similar, but Gray has narrow pale trailing edge to wing in all plumages. Black Currawong has thicker bill and dark undertail. Loud ringing, clinking song, reminiscent of some lyrebird sounds.
