Nicobar Serpent-Eagle

A tiny-bodied sunbird in which breeding males are colorful and distinctive, and females and non-breeding males quite drab. Breeding males have a green back, a yellow belly, and extremely elongated central tail feathers. Females and non-breeding males have gray-brown upperparts and pale-yellow underparts. Similar to Nile Valley Sunbird, but there is very little overlap in range; males are distinguished by their lack of purple on the back and breast, and females by being darker overall and having a less distinct pale eyebrow. Also similar to female Beautiful Sunbird, but yellower below, with a shorter bill. The most common call is a rising “sweet,” and the song is a typical sunbird jumble. 

Antvireos, as the name, suggests, resemble vireos, with rather heavy bills and shortish tails. This species inhabits open understory in humid forest of tropical lowlands and foothills. Usually found as sluggish singles or pairs, at times moving with mixed-species feeding flocks. Male has gray face and breast with a broad dark mask. Female has rusty cap and plain face and breast with a whitish eyering.

An uncommon and dull nuthatch of open primary pine forests. Distinctive in its plainness, lacking any bright coloration; gray-backed and white-bellied, with a black line running from the eye to the shoulder. Does not have any warm colors under the vent, unlike Chestnut-vented and Eurasian Nuthatches.
