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 →

Rare
Under 5% of wildlife watchers report a Hume's Warbler sighting in Lisbon on a given day, based on 12 verified sightings from GBIF citizen-science data. It is the 69th most-seen of the 186 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
January
In that month about 20% of wildlife watchers report a Hume's Warbler in Lisbon on a given day, against under 5% in February to November, the lowest months. That is one of Lisbon's wettest months, with about 75 mm of rain against almost none 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.
38th of 54
Of the 54 cities where we can rate Hume's Warbler sightings, Lisbon ranks 38th at under 5%. 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 Lisbon (12 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.
