Phylloscopus kansuensis
The Gansu Leaf Warbler (Phylloscopus kansuensis) is a diminutive and often challenging-to-identify passerine, endemic to a relatively restricted breeding range in central China. Measuring approximately 10-11 cm in length and weighing just 6-8 grams, its slender form is characterized by olive-green upperparts, pale yellowish-white underparts, and a distinct pale supercilium that contrasts with a darker eye-stripe. Key identification features include its prominent double yellowish wing-bars, th...
Primarily inhabits high-altitude coniferous or mixed coniferous-broadleaf forests and dense scrub, typically between 2,500 and 3,800 meters during the breeding season.
Exclusively insectivorous, primarily consuming small invertebrates such as caterpillars, beetles, flies, and spiders, which it gleans from leaves and twigs.
This active, diurnal warbler spends its days ceaselessly gleaning insects from foliage within the mid-canopy and understory, often flicking its tail. Foraging involves agile movements, short hovering flights, and quick hops among branches, showcasing its acrobatic ability. During the breeding sea...
