The black-crested bulbul (Rubigula flaviventris) is a member of the bulbul family of passerine birds. It is found from the Indian subcontinent to southeast Asia. The black-crested bulbul was originally described in the genus Vanga and later moved to the genus Pycnonotus. Pycnonotus was found to be polyphyletic in recent molecular phylogenetic studies and five bulbuls, including the black-crested bulbul, were moved to Rubigula.
Until 2008, the black-crested bulbul was considered as conspecific with the black-capped, ruby-throated, flame-throated and Bornean bulbuls, but these are all now treated as distinct. Wikipedia →

About 50% of wildlife watchers report a Black-crested Bulbul sighting in Doi Inthanon National Park on a given day, based on 1,960 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 3rd most-seen of the 367 birds we can rate there. Over three days the chance rises to about 90%, and over a week to over 90%, if each day is a fresh chance.

GBIF citizen-science records
It is estimated from how often the Black-crested Bulbul is recorded against all the birds logged in Doi Inthanon National Park (1,960 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.
