The mangrove blue flycatcher (Cyornis rufigastra) is a species of bird in the family Muscicapidae. It is native to Brunei, Indonesia, Malaysia, the Philippines, Sri Lanka, Singapore, and Thailand. Its natural habitat is subtropical or tropical mangrove forests. Clements splits the Kalao blue flycatcher, Cyornis kalaoensis into a distinct species. The IOC still lists it as a subspecies of the mangrove blue flycatcher. Wikipedia →

Likely
About 50% of wildlife watchers report a Mangrove Blue-Flycatcher sighting in Bako National Park on a given day, based on 90 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 12th most-seen of the 70 birds we can rate there. Over three days the chance rises to about 80%, and over a week to over 90%, if each day is a fresh chance.
March and June
In those months about 60% of wildlife watchers report a Mangrove Blue-Flycatcher in Bako National Park on a given day, against about 20% in October, the lowest month. November and December have too few records to rate.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Mangrove Blue-Flycatcher sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 3 parks where we can rate Mangrove Blue-Flycatcher sightings, Bako National Park has the highest daily chance: about 50%. Next come Way Kambas National Park (Indonesia, under 5%) and Kinabatangan Wildlife Sanctuary (Malaysia, under 5%).
GBIF citizen-science records
It is estimated from how often the Mangrove Blue-Flycatcher is recorded against all the birds logged in Bako National Park (90 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.
