Sumatran Flowerpecker

Uncommon medium-sized brownish bird of Andean montane forest from Venezuela through Ecuador and just barely into Peru. Distinctive among treehunters with its bold buffy streaking covering the entire head, back, and body. Rufous wings and tail. Sexes alike. Usually found singly or in pairs moving furtively through the understory of forest, often around bamboo, from around 2,200–3,500 m. Does not typically follow mixed-species flocks.

A newly described species endemic (at least as a breeder) to a few pockets of northern China. Essentially visually identical to Red-flanked Bluetail: adult male is sky-blue above and pale below, with orange sides and a small white eyebrow. Female and juvenile are more subdued, but still have the rufous flanks and blue tail. Breeds in humid montane forest, often favoring mossy, damp areas. Wintering range and habits essentially unknown, but probably overlap those of Red-flanked Bluetail. Can be hyperactive, moving quickly across the forest floor, stopping to flick the tail downwards. Best identified by range and distinctive song: a short, descending sweet yet burry phrase repeated regularly, very different from the song of Red-flanked Bluetail. Also has a variety of calls that are less distinctive, including a rising “sweet”, a descending “seet”, and a series of low, dry notes.

A tiny, warbler-shaped songbird confined to the eastern Lesser Sundas. Upperparts gray-brown; underparts clean, unmarked white. Note subtle white mark between bill and eye, and beady-eyed appearance. Juveniles washed yellow below. Inhabits forest, edge, mangroves, and scrub from coast to mountains. Sits high in the understory, singly or in pairs. Unmistakable, as the only tiny gray-and-white warbler-like bird in range. Warbling song comprises a series of high-pitched, descending whistled phrases such as “pee-pee-ooo-ooo-pee-ooo-ooo”. Calls often and for prolonged periods.
