Sumatran Whistling-Thrush

Medium-sized flycatcher-like bird with a long pointed bill. Male is bright white with a black face and throat. Female is entirely dark overall. Juvenile is rufous above and paler buff below. Endemic to the Chuuk Islands of Micronesia, where it primarily inhabits remnant upland native forest, extensive mangroves, and small forested atolls. Less frequently in degraded lowland forest. Favors areas with a dense understory, where it forages singly or in small groups, moving slowly through the foliage. Sparse and declining as a result of habitat loss. Gives low whistles and a nasal “jeer!”

This chunky bird is dingy yellow below and dark brownish above with a tawny crown. Sexes similar. Could be confused with Yellow-breasted Brushfinch, which is found at higher elevations and has a brighter rufous crown. Pairs or small groups are found foraging in the lower levels of montane forest, edges and tangles, often clambering around a couple meters from the ground. Found from around 600–2,500 m.

Medium-sized antpitta. Typical antpitta shape: plump and short-tailed with long legs, like a grapefruit on stilts. Mostly brown with a brighter cinnamon belly and grayish crown. Note blotchy white mustache stripe. Very similar in appearance to Scaled Antpitta but typically occurs at slightly higher elevations. Moustached has a less pronounced scaly pattern on the upperparts, browner cheeks, and a slower, higher-pitched song without a stutter in the middle than Scaled Antpitta. Fairly rare and local within limited range in the Andes of Colombia and Ecuador. Occurs in mossy cloud forest in the lower subtropics from around 1,850–2,000 m. Very rarely seen; typically stays hidden in the dense understory, occasionally hopping onto forest trails at dawn or dusk.
