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 →

Rare
Under 5% of wildlife watchers report a Large-billed Leaf-Warbler sighting in Kolkata on a given day, based on 167 verified sightings from GBIF citizen-science data. It is the 130th most-seen of the 247 birds we can rate there. Over three days the chance rises to under 5%, and over a week to about 10%, if each day is a fresh chance.
April
In that month about 10% of wildlife watchers report a Large-billed Leaf-Warbler in Kolkata on a given day, against under 5% in May to March, the lowest months. That is one of Kolkata's driest months, with about 50 mm of rain against 330 mm in July.
Between 3 and 6 am
Across all the parks we cover, that three-hour window holds the most Large-billed Leaf-Warbler sightings with a recorded time, and about half of them come between 6 pm and 6 am: it is most active around dawn and dusk.
Yes
Of the 4 cities where we can rate Large-billed Leaf-Warbler sightings, Kolkata has the highest daily chance: under 5%. Next come Dhaka (Bangladesh, under 5%) and Jabalpur (India, under 5%).
GBIF citizen-science records
It is estimated from how often the Large-billed Leaf-Warbler is recorded against all the birds logged in Kolkata (167 verified sightings), 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.
