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.

Rare
Under 5% of wildlife watchers report a Mangrove Whistler sighting in Singapore on a given day, based on 25 verified sightings from GBIF citizen-science data. It is the 248th most-seen of the 298 birds we can rate there. Over three days the chance rises to under 5%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Mangrove Whistler in Singapore on a given day, so our monthly data shows no clear season.
Between 3 and 6 am
Across all the parks we cover, that three-hour window holds the most Mangrove Whistler 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 Singapore, in our data
Singapore is the only city on Wallace's Line with enough records to rate Mangrove Whistler sightings: under 5% of wildlife watchers there report one on a given day.
Same order: Passeriformes
The closest relatives of the Mangrove Whistler that you can see in Singapore (order Passeriformes, Perching Birds) are Javan Myna (about 80%), Yellow-vented Bulbul (about 70%) and Black-naped Oriole (about 70%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Mangrove Whistler is recorded against all the birds logged in Singapore (25 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.
