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 →

Rare
Under 5% of wildlife watchers report a Sulphur-bellied Warbler sighting in Mumbai on a given day, based on 99 verified sightings from GBIF citizen-science data. It is the 165th most-seen of the 283 birds we can rate there. Over three days the chance rises to under 5%, and over a week to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Sulphur-bellied Warbler in Mumbai on a given day, so our monthly data shows no clear season.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Sulphur-bellied Warbler sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.

GBIF citizen-science records
It is estimated from how often the Sulphur-bellied Warbler is recorded against all the birds logged in Mumbai (99 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.
