Ribbon-tailed Astrapia
Astrapia mayeri
A long-tailed bird of upper montane forest. The male has an iridescent green head and bib with a black chest band bordered with a thin gold stripe. Note the outlandishly long, white tail streamers. Female is blackish with barring on the belly and some iridescence on the head. Mainly eats fruit. Similar to Stephanie’s Astrapia, but Ribbon-tailed usually occurs at higher elevations. The female Ribbon-tailed has iridescence on the head and the male’s tail is white rather than black. Voice, excited, pulsing rasps.
Isabelline Bush-hen
Amaurornis isabellina
A large, long-legged rail with rich chestnut underparts, duller brown upperparts, a greenish bill, and greenish-yellow legs. Typically encountered in pairs or small groups within dense, rank grassland or thick scrub, in the lowlands and lower hills on Sulawesi. In its limited range, most likely to be confused with female Watercock, but the bush-hen lacks any markings on the upperside and has brighter, chestnut-colored underparts. Noisy, giving harsh “tak-tak-tak-tak” calls in addition to rasping “groOw-groOw-groOw…”.
White-tailed Lark
Mirafra albicauda
A small, compact lark with blackish upperparts that appear very scaly in fresh plumage, a bold whitish eyebrow that starts in front of the eye, and a pale belly that contrasts strongly with blotchy blackish breast streaks. The stout bill is bicolored: pale below and dark on the tip and ridge of the upper mandible. Tail is mostly dark with bold white outer feathers that are conspicuous in flight. Resident in cropped grassland, mostly on black cotton soils, preferring lake edges. Somewhat furtive, preferring to dart into cover rather than parade in the open. Sings a rambling set of whistles, churrs, and chips in a protracted aerial display, lacking trills and with a simpler structure than Singing Bushlark. Other similar larks are less strongly contrasting, with more tawny-gray tones in the plumage.
