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
servant and ornithologist based in India. The genus name Phylloscopus is from Ancient Greek phullon, "leaf", and skopos, "seeker" (from skopeo, "to watch"). Like most similar songbirds, it was formerly included in the "Old World warbler" assemblage.
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.
Its song is buzzing and high-pitched. The best distinction from the yellow-browed warbler is the more disyllabic call. While the eastern and western Hume's leaf warblers already show noticeable... Wikipedia →

Possible
About 20% of wildlife watchers report a Hume's Warbler sighting in Kathmandu on a given day, based on 1,267 verified sightings from GBIF citizen-science data. It is the 33rd most-seen of the 312 birds we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
November to March
In those months about 40% of wildlife watchers report a Hume's Warbler in Kathmandu on a given day, against under 5% in June to September, the lowest months. Those are among Kathmandu's driest months, with about 10 mm of rain a month against 280 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.
11th of 54
Of the 54 cities where we can rate Hume's Warbler sightings, Kathmandu ranks 11th at about 20%. The best odds are in Dushanbe (Tajikistan, about 50%), Tashkent (Uzbekistan, about 50%) and Dehradun (India, about 40%).
Same genus: Phylloscopus
The closest relatives of the Hume's Warbler that you can see in Kathmandu (genus Phylloscopus, Leaf Warblers) are Grey-hooded Warbler (about 20%) and Greenish Warbler (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Hume's Warbler is recorded against all the birds logged in Kathmandu (1,267 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.
