The black bulbul (Hypsipetes leucocephalus), also known as the Himalayan black bulbul or Asian black bulbul, is a member of the bulbul family of passerine birds.

There are a number of subspecies, mostly varying in the shade of the body plumage which ranges from grey to black, and some also occur in white-headed morphs, as also suggested by its specific epithet leucocephalus, literally "white head". The legs and bill are always rich orange-red.
The black bulbul was formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's Systema Naturae. He placed it with the thrushes in the genus Turdus and coined the binomial name Turdus leucocephalus. Gmelin based his account on "Le Merle Dominiquain de la Chine", a white-headed morph from China that had been described in 1782 by the French naturalist Pierre Sonnerat. The type locality was subsequently restricted to Guangzhou (formerly Canton... Wikipedia →

Rare
Under 5% of wildlife watchers report a Black Bulbul sighting in Hong Kong on a given day, based on 9 verified sightings from GBIF citizen-science data. It is the 174th most-seen of the 204 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
In every month with enough records, under 5% of wildlife watchers report a Black Bulbul in Hong Kong on a given day, so our monthly data shows no clear season.
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.
23rd of 23
Of the 23 cities where we can rate Black Bulbul sightings, Hong Kong ranks 23rd at under 5%. 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 Hong Kong (family Pycnonotidae, Bulbuls) are Red-whiskered Bulbul (about 90%), Light-vented Bulbul (about 80%) and Chestnut Bulbul (about 10%), 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 Hong Kong (9 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.
