Black-chinned Whistler
Pachycephala mentalis
A chunky, thick-billed songbird from the Moluccas. Unmistakable male shows a black head, a yellow collar, a conspicuous white throat, a black chest line, and vibrant yellow underparts. Female is subdued, with a grayish head, a paler throat, and yellow-washed underparts. Juveniles resemble female, but are washed with rufous. Pairs and singles can be found in forest, edge, scrub, and mangroves from lowlands to hills, but are typically most abundant at higher elevations. Female’s yellow wash on the underside separates her from Obi and Drab Whistlers, and olive-toned upperside further differentiates her from Drab Whistler. Calls include a soft “chow-chow-chow,” sometimes terminating in a whipping “chee-wee-CHOW!”
识别特征
The black-chinned whistler is the northernmost member of the golden whistler group, being bordered to the south by the yellow-throated whistler. The black-chinned whistler is relatively large, and males are white-throated, have an incomplete black chest-band (only distinct in the center of the chest; does not connect to the black head) and a small black chin (lacking in Obi Islands).
分类信息
It is variably considered a subspecies of the Australian golden whistler or treated as a separate species, but strong published evidence in favour of either treatment is limited, and further study is warranted to resolve the complex taxonomic situation.<p>Three subspecies are recognized:

Finn's Weaver
Ploceus megarhynchus
Range-restricted weaver with a powerful dark bill. Male is predominantly yellow with a dark cheek patch. Female is streaky brown above and paler below; lacks the strong streaking and facial patterns of Streaked and Black-breasted Weavers. Female Finn’s is similar to female Baya Weaver, but note the darker coloration, lack of a pale brow stripe, and heavier, sharper-looking bill in female Finn’s. Inhabits open areas with scattered trees; favors wet areas. Colonial nester; males build ball-shaped nests, often in cotton trees.
White-bellied Thicket-Fantail
Rhipidura leucothorax
A medium-sized, long-tailed bird of lowland and foothill wooded thickets. Blackish plumage with short white eye-brow, white patch on the side of the throat and prominent white tail tips. Also white-spotted chest and wing bars. Secretive and difficult to see. Keeps to cover with tail often cocked and fanned. Similar to Black Thicket-Fantail, but White-bellied unsurprisingly has a white belly. Also similar to Sooty Thick-Fantail but has the white tail tips. Voice, a falling note followed by a high-pitch ringing note “joo-wii!”
Ocellated Tapaculo
Acropternis orthonyx
The antithesis of a typical tapaculo, Ocellated is large and spectacular. The body is mostly black and covered with bright white spots. The face and rump are bright rufous. Look for the daggerlike hindclaws, which are used to scrape the ground in search of insects. Sexes alike. This chunky bird is quite shy, staying on or near the ground among thick understory and bamboo thickets in montane forest from 2,300–3,500 m. Not usually seen without considerable effort. Listen for its loud descending whistle, “wheeeu.”
