The Lemon-rumped Warbler (Phylloscopus chloronotus), also known as the Pale-rumped Warbler, is a small species of Old World warbler in the family Phylloscopidae. It is native to the Himalayas, breeding in montane forests and wintering in the southern foothills and the Purvanchal Range. The species is structurally identical to the Sichuan Leaf Warbler (Phylloscopus forresti), but differs in vocalizations.
The Lemon-rumped Warbler was once grouped with the Sichuan Leaf Warbler (Phylloscopus forresti) and was previously classified within P. proregulus. Vocal and genetic studies confirmed its separation as a distinct species. Related taxa in China, including P. kansuensis and P. yunnanensis, are also now recognized as separate.
The Lemon-rumped Warbler is 9–10 cm long and weighs about 4.6–5.1 g. It has a whitish crown stripe bordered by darker olive-brown sides, a pale line above the eye, and a dark eyestripe that often curves downward.

The underparts are whitish or... Wikipedia →

With luck
About 10% of wildlife watchers report a Pale-rumped Warbler sighting in Srinagar on a given day, based on 27 verified sightings from GBIF citizen-science data. It is the 52nd most-seen of the 120 birds we can rate there. Over three days the chance rises to about 20%, and over a week to about 30%, if each day is a fresh chance.
December
In that month about 20% of wildlife watchers report a Pale-rumped Warbler in Srinagar on a given day, against under 5% in February and May–October, the lowest months. That is one of Srinagar's driest months, with about 30 mm of rain against 100 mm in March.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Pale-rumped Warbler sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is most active around dawn and dusk.
Among the best
Of the 3 cities where we can rate Pale-rumped Warbler sightings, Srinagar ranks 2nd at about 10%, level with the leaders once rounded. The best odds are in Dehradun (India, about 10%).
GBIF citizen-science records
It is estimated from how often the Pale-rumped Warbler is recorded against all the birds logged in Srinagar (27 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.
