The large-billed leaf warbler (Phylloscopus magnirostris) is a species of migratory leaf warbler (family Phylloscopidae) found in Asia. This is a somewhat large leaf warbler with a single wing bar and a prominent yellowish-whitesupercilium. A contrasting broad and dark eye stripe extending behind the eye, a large darkish upper mandible and a distinctive call set it apart from most other leaf warblers in its range. It has a dark crown and greyish ear-coverts. It can be confused with an Arctic warbler.
Breeding in central China and the Himalayas, it winters in Sri Lanka, the Western Ghats and associated hill ranges. It is found in dense vegetation. It has also been observed in urban areas on occasion. It is more often heard than seen. The two note dir-tee call with the second note much higher is distinctive. Another call is a single faint note followed by a series of paired-notes descending evenly. They call often and at regular intervals. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Large-billed Leaf-Warbler is recorded against all the birds logged in Horton Plains National Park (128 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
