The sooty-headed bulbul (Pycnonotus aurigaster) is a species of songbird in the Bulbul family, Pycnonotidae. It is found in south-eastern Asia. Its natural habitat is subtropical or tropical moist lowland forests. A medium-sized songbird measuring between 18 and 21 centimetres in length with a short crest, the sooty-headed bulbul can be distinguished from the similar red-vented bulbul by its tan front, less extensive area of black on its head and gold-colored vent in certain subspecies. Its call is a series of whistled notes similar in tone to that of the red-whiskered bulbul, but delivered in a more hurried manner.
The sooty-headed bulbul was originally described in the genus Turdus. Alternate names for the sooty-headed bulbul include the golden-vented bulbul and several names used for other species (black-capped, red-vented, white-eared and yellow-vented bulbul).

Rare
Under 5% of wildlife watchers report a Sooty-headed Bulbul sighting in Hong Kong on a given day, based on 123 verified sightings from GBIF citizen-science data. It is the 64th most-seen of the 204 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
February, May–July and October
In those months about 10% of wildlife watchers report a Sooty-headed Bulbul in Hong Kong on a given day, against under 5% in March–April, August–September and November–January, the lowest months.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Sooty-headed 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 17
Of the 17 cities where we can rate Sooty-headed Bulbul sightings, Hong Kong ranks 13th at under 5%. The best odds are in Hanoi (Vietnam, about 60%), Xiuying District (China, about 50%) and Kunming (China, about 40%).
Same genus: Pycnonotus
The closest relatives of the Sooty-headed Bulbul that you can see in Hong Kong (genus Pycnonotus, Typical Bulbuls) are Red-whiskered Bulbul (about 90%) and Light-vented Bulbul (about 80%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Sooty-headed Bulbul is recorded against all the birds logged in Hong Kong (123 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.
