Crow-billed Drongo
Dicrurus annectens
Large dark drongo of open forested environments. Glossy black with a characteristically forked tail. Immature speckled with grayish-white on lower breast and belly. Thick dark bill gives a generally heavier-headed appearance than other similar dark drongos such as Black Drongo, with which it shares parts of its range; also prefers more forested environments than the latter. Aggressive and territorial, particularly during the breeding season, frequently mobbing raptors and corvids with great vigor. Like other drongos, boasts a varied repertoire; songs include a ringing “tsee-goo-gohgee!” Calls include bell-like gurgling notes, harsh chattering, and piercing whistles.

分类信息
The crow-billed drongo was originally described by the English naturalist Brian Houghton Hodgson in 1836 and given the binomial name Bhuchanga annectans. The specific epithet is a misspelling of the Latin word annectens meaning "connecting". This error has been corrected following the rules of the International Commission on Zoological Nomenclature to give the current scientific name Dicrurus annectens. The present genus Dicrurus had been introduced by the French ornithologist Louis Pierre Vieillot in 1816.

行为
This species inhabits dense evergreen forests and moist-deciduous forests. The nesting season is from April to June. The nest is usually a small cup made of grass that is held together by cobwebs. The nests can be found in the fork of a slender branch. The female incubates the eggs. However, both the male and female birds build the nest.

Taliabu Fantail
Rhipidura sulaensis
A lively little rufous songbird with a conspicuously long tail that is often cocked and fanned. Upperside is rufous except for darker brown band at end of tail. Head is earth-brown with a rufous brow and a striking white throat. Black chest patch contrasts with buff underparts. Pairs or single birds regularly attend mixed-species flocks, mainly in forests of foothills and mountains, but also within lowlands. Restricted to Taliabu Island, where it is the only fantail. Song is a sequence of descending tinkling notes, followed by tremulous notes up and down the scale. Call is a low-pitched “chep.”
Australian Yellow White-eye
Zosterops luteus
Small songbird of coastal northern and northwestern Australia. Green above, yellow below, with yellow lores and bright white eyering. Feeds in small flocks in the foliage of small bushes, trees, and mangroves. Thin, high-pitched calls, similar to Silver-eye, but notes shorter, more clipped.
Black-and-white Mannikin
Spermestes bicolor
Small, big-billed, short-tailed waxbill. Shows profound geographical variation: a rufous back in southeastern Africa, and a black back in central and western Africa. Black-backed birds vary from having white barring on the wings and tail to having completely black wings and tail. Juveniles are very drab and brown but can usually be identified by their association with adults. Found in forest, moist woodland, and gardens, often in patches of seeding grass. Usually in small flocks. Call is a descending “teew”. Similar to Bronze Mannikin but has an all-blue bill and never shows a brown back.
