Dapple-throat

Arcanator orostruthus

Supreme understory skulker in montane forest, resembling a hybrid between a thrush and babbler. A dull and dowdy understory specialist with brown-olive upperparts and boldly-streaked cream-yellow underparts. Immature is more uniformly olive. Singles or pairs are highly localized residents working the leaf-litter in rich wet undergrowth of Eastern Arc montane forest, between 900–1800m, especially close to streams; shy and hops or runs quickly across forest-floor, seldom permitting absorbing looks. Vocalizations are variable, but most frequently utters a rich and fluty song “we-lu-we-lu-wel’li-lu” and sweet bulbul-like chattering calls. The Dapple-throat resembles immature robin-chats or thrushes, but lacks spotting and scaling on the upperparts.

Red-shouldered Blackbird

Red-shouldered Blackbird

Agelaius assimilis

A mostly black inhabitant of swamps and marshes. The male has a telltale orange-red shoulder patch with pale yellow trim, which the female lacks. Both sexes of Tawny-shouldered Blackbird have a yellow-orange shoulder, though the shoulder color is sometimes only visible in flight. The Shiny Cowbird lacks a shoulder patch, is quite glossy, and has a shorter and stouter bill than Red-shouldered Blackbird. The call is a “chut” or “chut-chut” and song is a shrill “Shuh-reee-eee.”

Vega Gull

Vega Gull

Larus vegae

A large, sturdy gull of East Asia. Adults have a fairly pale gray back, pale eye, and dull pinkish legs. Takes four years for immatures to progress from mostly brown to fully white and gray adult plumage; intermediate plumages are often mottled and messy. Extremely variable plumage can make identification tricky. Occurs inland and along the coast, frequenting river mouths, harbors, beaches, lakes, and ponds. Often forms flocks with other gulls. Back color of adults generally a shade darker than that of American Herring Gull. Very similar to Mongolian Gull, and separation is tricky, but has a larger head and bill; adults also generally have pinker legs.

Sulawesi White-eye

Sulawesi White-eye

Zosterops consobrinorum

A small songbird with a bold white eye-ring, dark eyes, a green back and forehead, a yellow throat and base to undertail, and a white belly. Groups and pairs roam woods, forest edges and patches, gardens, cultivated spaces, and scrub. Confined to lowlands of southeast Sulawesi. Occurs at lower elevations than Warbling White-eye, and differs from it in the dark eye and green forehead. Separated from Lemon-bellied White-eye by the white belly. Gives a slow-paced, high-pitched descending tinkling song, “chi-chiwit-chit-cher-cher.” Also high “zit” notes.
