Red-billed Scimitar-Babbler

Dark brown, fork-tailed seabird of the northwestern and central Pacific, where it breeds on Japanese and Hawaiian islands. Generally forages far offshore and does not associate with boats. Dark chocolate-brown overall with prominent pale carpal bars. In optimal light, rump is slightly paler than the plumage of the back and tail, unlike in Markham’s and Leach’s Storm-Petrels; in fresh plumage, note gray sheen to head and back. Lacks the distinctively pale primary shafts of Matsudaira's and Swinhoe’s Storm-Petrels.

Huge white bird with a long elegant neck. North American “Whistling” Tundras have a mostly black bill, with a yellow spot near the eye; Eurasian “Bewick’s” have a more evenly divided black-and-yellow bill. Immatures dusky gray-brown with pink on bill. Easily confused with Whooper and Trumpeter Swans where their ranges overlap; see those species’ accounts. Breeds on ponds and tundra in far north. Winters in large flocks on fresh or saltwater. Forages in shallow, vegetated wetlands, reaching under the water for plants, and walks through corn stubble. Gives loud echoing bugles, often while in flight.

A small widowbird. The breeding male is jet black, with a crimson band across the breast, and a 20-centimeter floppy graduated tail. All-black birds and birds with a reduced crimson band, also occur. The female and non-breeding male have dark streaked upperparts, pale unstreaked or faintly streaked underparts, and a yellowish eyebrow and face, and lack the long tail. Pairs breed in open grassland, savanna, scrub, and cultivated areas. The species may flock, often with other seedeaters, and move locally when breeding is over. Breeding males are distinctive, but non-breeding males and females can be confused with many other species. Can be tentatively identified by lack of red or yellow in the wing, along with a buffy breast that is unstreaked or only lightly streaked.
