The grey-bellied bulbul (Ixodia cyaniventris) is a species of songbird in the bulbul family. It is found on the Malay Peninsula, Sumatra and Borneo. Its natural habitat is subtropical or tropical moist lowland forests. It is threatened by habitat loss.
This species was previously placed in the large bulbul genus Pycnonotus, which was found to be polyphyletic in molecular phylogenetic studies, resulting in three species, including the grey-bellied bulbul, being moved to Ixodia. Some authorities use Ixidia for the genus name because Ixodia was thought to be preoccupied.

Rare
Under 5% of wildlife watchers report a Gray-bellied Bulbul sighting in Kuala Lumpur on a given day, based on 33 verified sightings from GBIF citizen-science data. It is the 145th most-seen of the 228 birds we can rate there. Over three days the chance rises to under 5%, and over a week to about 10%, if each day is a fresh chance.
March
In that month about 10% of wildlife watchers report a Gray-bellied Bulbul in Kuala Lumpur on a given day, against under 5% in April to February, the lowest months.
Between 3 and 6 am
Across all the parks we cover, that three-hour window holds the most Gray-bellied Bulbul sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is most active around dawn and dusk.
Only Kuala Lumpur, in our data
Kuala Lumpur is the only city on Wallace's Line with enough records to rate Gray-bellied Bulbul sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Gray-bellied Bulbul is recorded against all the birds logged in Kuala Lumpur (33 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.
