About Phylloscopus magnirostris Blyth, 1843
The large-billed leaf warbler, with the scientific name Phylloscopus magnirostris, is a migratory leaf warbler species belonging to the family Phylloscopidae, and it occurs in Asia. This species is a somewhat large leaf warbler, marked by a single wing bar and a prominent yellowish-white supercilium. Several features distinguish it from most other leaf warblers across its range: a contrasting broad dark eye stripe that extends behind the eye, a large darkish upper mandible, and a distinctive call. It also has a dark crown and greyish ear-coverts, and it can be misidentified as an Arctic warbler. This warbler breeds in central China and the Himalayas, and winters in Sri Lanka, the Western Ghats, and connected hill ranges. It typically inhabits dense vegetation, though it has occasionally been observed in urban areas. It is more frequently detected by its call than by sight. Its most distinctive call is a two-note dir-tee, where the second note is much higher in pitch. Another call consists of a single faint note, followed by a series of paired notes that descend evenly in pitch. Individuals call often, at regular intervals.
