The sulphur-bellied warbler (Phylloscopus griseolus) is a species of leaf-warbler found in the Palearctic region (Afghanistan, Kazakhstan, Kyrgyzstan, Mongolia, Russian Federation [Central Asian Russia], Tajikistan and Turkmenistan). It was earlier also known by the name of olivaceous leaf-warbler.
Like other leaf-warblers, it gleans insects from small branches and leaves. It is found in rocky hill and scrub forest habitats. The species is found in small groups and has a tendency to forage low in the vegetation, sometimes even hopping on the ground. It has a single note cheep call. Wikipedia →

Under 5% of wildlife watchers report a Sulphur-bellied Warbler sighting in Jim Corbett National Park on a given day, based on 10 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 328th most-seen of the 368 birds we can rate there. Over three days the chance rises to under 5%, if each day is a fresh chance.
Any time of year

GBIF citizen-science records
It is estimated from how often the Sulphur-bellied Warbler is recorded against all the birds logged in Jim Corbett National Park (10 verified sightings from 2019 to 2026), 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.
