Phylloscopus claudiae
The Claudia's Leaf Warbler, *Phylloscopus claudiae*, is a diminutive and often elusive member of the Old World Warbler family, known for its intricate song and active foraging behavior. Measuring approximately 10-11 cm in length with a wingspan of 16-18 cm and weighing a mere 6-9 grams, it exhibits typical *Phylloscopus* characteristics: dull olive-green upperparts, paler, often yellowish-white underparts, and a distinct pale supercilium (eyebrow stripe) that contrasts with a dark eye-stripe....
This species primarily inhabits broadleaf and mixed deciduous forests, preferring areas with a dense understory of shrubs and saplings, typically found at elevations between 800 and 2,500 meters.
Primarily insectivorous, feeding on small insects, their larvae, and spiders gleaned from leaves and twigs in the forest canopy and understory, occasionally catching flying insects mid-air.
Claudia's Leaf Warblers are highly active insectivores, constantly flitting through the canopy and mid-story foliage in search of prey, often employing a characteristic 'hover-gleaning' technique. They are diurnal, spending their nights roosting communally or individually within dense foliage, pa...
Claudia's Leaf Warbler breeds across a discontinuous range in the montane forests of East Asia, primarily found in the southern regions of China (Yunnan, Sichuan, Guizhou provinces) and extending into northern Myanmar, Laos, and Vietnam. Its breeding elevation typically ranges from 800 to 2,500 m...
