The Chinese leaf warbler is a species of Old World warbler in the family Phylloscopidae. Its natural habitats are subtropical or tropical dry forests and subtropical or tropical high-altitude shrubland. It is found only in China.
Region
Southwest and central China
Typical Environment
Occurs in montane forests and high-altitude shrublands, favoring edges of coniferous and mixed broadleaf woods. It also occupies secondary growth, bamboo thickets, and rhododendron scrub where insect prey is abundant. In winter it can descend into lower montane valleys with dense understory. The species is generally patchy but local within suitable habitat.
Altitude Range
1200–3600 m
Climate Zone
Highland
Ease of Keeping
Beginner friendly: 1/5
A small leaf warbler named after Yunnan, it is best identified by its bright pale supercilium and two distinct wingbars. It forages actively among foliage, often joining mixed-species flocks in montane forests. The species undertakes local altitudinal movements in response to seasonal weather and food availability.
Temperament
active and restless
Flight Pattern
short rapid wingbeats with quick darting between branches
Social Behavior
Usually seen singly or in pairs during the breeding season, defending small territories. Outside breeding, it often joins mixed-species flocks while foraging through canopy and midstory. Nests are cup-shaped and placed low in dense shrubs or ground vegetation.
Migratory Pattern
Partial migrant
Song Description
A high-pitched, thin series of twitters and trills delivered in short phrases. Calls include sharp 'tsee' notes used while foraging and maintaining contact.
Plumage
Olive-green upperparts with pale whitish to yellowish underparts and a clean, delicate texture typical of leaf warblers. Prominent pale supercilium and two pale wingbars on a darker wing. Fine bill and relatively plain crown with a subtle dark eyestripe.
Diet
Feeds primarily on small insects and other arthropods, including caterpillars, aphids, and spiders. It gleans prey from leaves and twigs and occasionally makes short sallies to snatch flying insects. Foraging is methodical but brisk, with frequent hovering to inspect leaf undersides.
Preferred Environment
Most often feeds in the canopy and midstory of montane forests, along forest edges, and in dense shrubbery. It also forages in bamboo and rhododendron thickets where insect densities are high.
