Lemon-rumped Warbler

The lemon-rumped warbler, also known as the pale-rumped warbler, is a small leaf warbler 9–10cm long and 4.6–5.1g. It has a whitish crown stripe bordered by darker olive-brown sides, a pale line above the eye and a dark eyestripe that often curves downward. It is structurally identical to the Sichuan leaf warbler but differs in vocalisations (Wikipedia, general species account).

It breeds across the Himalayas from northern Pakistan through Nepal into India, Bhutan and China, in spruce and fir forests with rhododendron and broadleaf trees and in lower oak and broadleaf stands near the conifer zone. Nests are 2–15m above the ground, usually in conifers, and the diet consists mainly of insects and larvae. Two subspecies are recognised, and winter records occur from 300 to 2,700m (Wikipedia, general species account).
