Dusky Fulvetta

Little-known swift found mostly in mountainous areas, though flocks occasionally venture into lowlands. All dark with short square tail and angular wings. Namesake white spots on forehead and behind eyes are distinctive, but these can be extremely difficult to see. Many swifts are best left unidentified. Sex and age variation not well known; some birds, maybe juveniles, can show whitish scaling on belly. Occasionally seen singly or mixed with flocks of other swifts, but most often in monotypic flocks of up to several dozen individuals. Voice can be helpful with practice; typically a staccato chatter followed by “pew pew pew” notes like a laser gun.

Tiny bird of forest canopy; difficult to see well and heard far more than seen. Appears mostly yellow from below. In addition to tiny size, note limited black streaking on breast and large bill. Found in tall lowland forest and occurs mostly in pairs that do not typically join mixed-species flocks; seems more common near rivers but is also likely to be found away from them. Sits still and darts out to snatch insects from foliage. Call is an incisive, doubled metallic note; also indistinct ticking.

A relatively thick-bodied, long-tailed warbler, prone to creeping like a mouse low in vegetation. Dark brown above. Chest and face paler orange-rusty with a dark eye-stripe. Belly darker than chest. Found in dense dark stands of bamboo, ferns, and forest undergrowth above 900 meters of elevation. Voice reported to be a two-noted whistled phrase, followed by a single higher-pitched note.
