Rare
Under 5% of wildlife watchers report a Hainan Blue-Flycatcher sighting in Doi Inthanon National Park on a given day, based on 35 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 276th most-seen of the 367 birds we can rate there. Over three days the chance rises to under 5%, and over a week to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Hainan Blue-Flycatcher in Doi Inthanon National Park 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 Hainan Blue-Flycatcher sightings with a recorded time, and about half of them come between 6 am and 6 pm: it is most active around dawn and dusk.

The closest relatives of the Hainan Blue-Flycatcher that you can see in Doi Inthanon National Park (genus Cyornis, Blue Flycatchers and Jungle Flycatchers) are Hill Blue Flycatcher (about 20%) and Blue-throated Flycatcher (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Hainan Blue-Flycatcher is recorded against all the birds logged in Doi Inthanon National Park (35 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.
