Nicobar Imperial-Pigeon

Tiny and rather unobtrusive bird with brownish upperparts and luminous lemon-yellow underparts. Superficially similar to female and juvenile Olive-backed Sunbirds, but note gerygone’s short, uncurved bill. Forages in parks, forests, and plantations, where it often joins mixed flocks moving through the middle and upper layers. Song is variable throughout its range but invariably includes buzzy notes with obvious rises and falls in pitch.

Small, fairly colorful bird with a typical warbler shape. The head is mostly gray, the upperparts olive-green, the upper breast whitish, and the belly and lower breast rich yellow. Found in lush woodland and savanna. An active, restless bird that is usually in small groups. Similar to Yellow-bellied Eremomela, but longer-tailed and brighter overall, with a greener back and yellow extending up onto the lower breast. The apalis-like song is a long series of low-pitched “whichew” notes, usually given at dawn. The calls include a short trill and low scratchy notes. These calls are often given in chorus by a whole group. 

A medium-sized bird, brownish above and pale buff below, with a bright rufous rump and tail and a distinctive buffy line behind the eye. Found in tall rainforest, where it occurs mainly in the midstory and canopy, but occasionally in the understory. Will follow mixed species flocks at all levels. Feeds on insects and forages actively, often investigating dead leaf clusters and other accumulations of detritus. Song is a short, weak series of squeaking notes that fades away; call is a hard doubled note. Most similar to Rufous-tailed Foliage-gleaner but somewhat larger and more likely to occur at lower levels in the forest; both tail and rump are rufous in Rufous-rumped.
