The mangrove whistler (Pachycephala cinerea) is a species of bird in the family Pachycephalidae found in South-east Asia. Alternate names for the mangrove whistler include the grey thickhead and white-bellied whistler. The latter name should not be confused with the species of the same name, Pachycephala leucogastra. Formerly, both the green-backed and white-vented whistlers were considered to be subspecies of the mangrove whistler.

GBIF citizen-science records
It is estimated from how often the Mangrove Whistler is recorded against all the birds logged in Way Kambas National Park (11 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.
