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 Khao Yai National Park on a given day, based on 123 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 156th most-seen of the 278 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.
July
In that month about 20% of wildlife watchers report a Sooty-headed Bulbul in Khao Yai National Park on a given day, against under 5% in June and December–March, the lowest months. That is one of Khao Yai National Park's wettest months, with about 270 mm of rain against 15 mm in December.
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.
9th of 9
Of the 9 parks where we can rate Sooty-headed Bulbul sightings, Khao Yai National Park ranks 9th at under 5%. The best odds are in Tangkoko Nature Reserve (Indonesia, about 40%), Bali Barat National Park (Indonesia, about 40%) and Gunung Leuser National Park (Indonesia, about 30%). All parks ranked.
Same genus: Pycnonotus

GBIF citizen-science records
It is estimated from how often the Sooty-headed Bulbul is recorded against all the birds logged in Khao Yai National Park (123 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.
