Linnaeus specified the location as "China" but this was restricted to Hong Kong and Guangdong by Herbert Girton Deignan in 1948.

Possible
About 30% of wildlife watchers report a Red-whiskered Bulbul sighting in Sundarbans National Park on a given day, based on 367 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 42nd most-seen of the 177 birds we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
July
In that month about 50% of wildlife watchers report a Red-whiskered Bulbul in Sundarbans National Park on a given day, against about 10% in January, the lowest month. That is one of Sundarbans National Park's wettest months, with about 480 mm of rain against 15 mm in January. May and June have too few records to rate.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Red-whiskered Bulbul sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
13th of 22
Of the 22 parks where we can rate Red-whiskered Bulbul sightings, Sundarbans National Park ranks 13th at about 30%. The best odds are in Eravikulam National Park (India, about 80%), Periyar National Park (India, about 70%) and Mudumalai National Park (India, about 60%). All parks ranked.
Same order: Passeriformes
The closest relatives of the Red-whiskered Bulbul that you can see in Sundarbans National Park (order Passeriformes, Perching Birds) are Large-billed Crow (about 60%), Oriental Magpie-Robin (about 50%) and Bronzed Drongo (about 50%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Red-whiskered Bulbul is recorded against all the birds logged in Sundarbans National Park (367 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.
