With luck
About 10% of wildlife watchers report a Black Bulbul sighting in Dehradun on a given day, based on 894 verified sightings from GBIF citizen-science data. It is the 60th most-seen of the 280 birds we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
January and February
In those months about 30% of wildlife watchers report a Black Bulbul in Dehradun on a given day, against under 5% in May to October, the lowest months. Those are among Dehradun's driest months, with about 40 mm of rain a month against 370 mm in July.
Between 3 and 6 pm
Across all the parks we cover, that three-hour window holds the most Black 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.
12th of 23
Of the 23 cities where we can rate Black Bulbul sightings, Dehradun ranks 12th at about 10%. The best odds are in Taipei (Taiwan, about 60%), Taichung (Taiwan, about 50%) and Fuzhou (China, about 30%).
Same family: Pycnonotidae
The closest relatives of the Black Bulbul that you can see in Dehradun (family Pycnonotidae, Bulbuls) are White-cheeked Bulbul (about 70%) and Red-whiskered Bulbul (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Black Bulbul is recorded against all the birds logged in Dehradun (894 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.
