Rare
Under 5% of wildlife watchers report a Mangrove Blue-Flycatcher sighting in Way Kambas National Park on a given day, based on 8 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 191st most-seen of the 205 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
May and September
In those months about 10% of wildlife watchers report a Mangrove Blue-Flycatcher in Way Kambas National Park on a given day, against under 5% in March–April, June–August and October, the lowest months. November to February 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.
2nd of 3
Of the 3 parks where we can rate Mangrove Blue-Flycatcher sightings, Way Kambas National Park ranks 2nd at under 5%. The best odds are in Bako National Park (Malaysia, about 50%).
GBIF citizen-science records
It is estimated from how often the Mangrove Blue-Flycatcher is recorded against all the birds logged in Way Kambas National Park (8 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.
