The yellow-vented warbler is a species of leaf warbler. It was formerly included in the "Old World warbler" assemblage.
Region
Eastern Himalayas and Southeast Asia
Typical Environment
Found from the eastern Himalayan foothills through northeastern India, Bhutan, and Myanmar into southern China, Thailand, Laos, and Vietnam. It occupies subtropical broadleaf forests, forest edges, and bamboo thickets, often near streams and ravines. The species forages in the mid-story and canopy, moving restlessly through dense foliage. Outside the breeding season it may descend to lower elevations and use secondary growth and scrub. It frequently associates with mixed-species foraging flocks in suitable forest.
Altitude Range
300–2400 m
Climate Zone

Ease of Keeping
Beginner friendly: 1/5
A small leaf warbler noted for its bright yellow vent (undertail coverts), it actively gleans insects from foliage and often joins mixed-species flocks. The species was formerly placed among the broad “Old World warbler” assemblage before molecular studies grouped it within Phylloscopus. It undertakes local altitudinal movements, descending to lower elevations outside the breeding season.
An individual not from a bird wave, from Mahananda Wildlife Sanctuary, West Bengal.

Social Behavior
Usually seen singly or in pairs during the breeding season; otherwise often joins mixed-species flocks with other small insectivores. Nests are typically cup-shaped and placed low in dense vegetation or on banks. Both sexes are attentive foragers, moving quickly through mid-story foliage.

Partial migrant
Song Description
Song is a fast, high-pitched series of clear, ringing notes delivered in short phrases. Calls include sharp chips and thin seep notes used to keep contact while foraging.
