The chestnut bulbul or chestnut-backed bulbul (Hemixos castanonotus) is a songbird in the bulbul family, Pycnonotidae. The species was first described by Robert Swinhoe in 1870. It is found in southern China and northern Vietnam. Its natural habitat is subtropical or tropical moist lowland forests; it primarily resides in the canopy.
It is an omnivore. Formerly, some authorities classified the chestnut bulbul in the genus Hypsipetes and also as a subspecies of the ashy bulbul. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Chestnut Bulbul is recorded against all the birds logged in Suzhou (26 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.
