Hume's leaf warbler or Hume's warbler (Phylloscopus humei) is a small leaf warbler which breeds in the mountains of inner Asia. This warbler is migratory and winters mainly in India. The English name and the specific humei commemorate Allan Octavian Hume, a British civil

Hume's leaf warbler is one of the smallest "Old World warblers". Like most other leaf warblers, it has greenish upperparts and off-white underparts. With its long supercilium, crown stripe and yellow-margined tertial remiges, it is very similar to the yellow-browed warbler (P. inornatus). However, it has only one prominent light wing bar, just a faint vestige of the second shorter wing bar, and overall duller colours. It also has a dark lower mandible and legs.

With luck
About 10% of wildlife watchers report a Hume's Warbler sighting in Ranchi on a given day, based on 8 verified sightings from GBIF citizen-science data. It is the 59th most-seen of the 76 birds we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
December
In that month about 20% of wildlife watchers report a Hume's Warbler in Ranchi on a given day, against under 5% in April to November, the lowest months. That is one of Ranchi's driest months, with about 10 mm of rain against 350 mm in July.
Between 4 and 7 am
Across all the parks we cover, that three-hour window holds the most Hume's Warbler sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
31st of 54
Of the 54 cities where we can rate Hume's Warbler sightings, Ranchi ranks 31st at about 10%. The best odds are in Dushanbe (Tajikistan, about 50%), Tashkent (Uzbekistan, about 50%) and Dehradun (India, about 40%).
GBIF citizen-science records
It is estimated from how often the Hume's Warbler is recorded against all the birds logged in Ranchi (8 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.
