The pale-chinned flycatcher (Cyornis poliogenys) is a species of bird in the family Muscicapidae. It has also been known in the past as pale-chinned blue flycatcher (on the IOC World Bird List up to 2023), and Brook's flycatcher.
It is a medium-sized flycatcher, 15.5–18 cm (6.1–7.1 in) long. Both sexes are similar, dull bluish-grey on upper parts, and with a rufous chest, a whitish throat, and white below; the males lack the intense blue colours shown by many of the other mainland Asian species in the genus Cyornis.
Its nesting season is April–June. It is insectivorous. It is found in Bangladesh, Bhutan, China, India, Myanmar, and Nepal. Its natural habitat is subtropical or tropical moist lowland forests. It occurs at altitudes from sea level up to 1,600 metres.
There are four subspecies: C. p. poliogenys – central Himalaya to eastern Bangladesh and southwestern Myanmar. C. p. cachariensis – eastern Himalaya to south-central China and northern Myanmar. Differs from the nominate in being more strongly bluish above and orangey below. Wikipedia →

Possible
About 20% of wildlife watchers report a Pale-chinned Blue-Flycatcher sighting in Manas National Park on a given day, based on 282 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 81st most-seen of the 377 birds we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
June
In that month about 40% of wildlife watchers report a Pale-chinned Blue-Flycatcher in Manas National Park on a given day, against about 10% in July–August, October and December–February, the lowest months. That is one of Manas National Park's wettest months, with about 1070 mm of rain against 10 mm in December.
Between 2 and 5 pm
Across all the parks we cover, that three-hour window holds the most Pale-chinned Blue-Flycatcher sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 6 parks where we can rate Pale-chinned Blue-Flycatcher sightings, Manas National Park has the highest daily chance: about 20%. Next come Chitwan National Park (Nepal, about 10%) and Kaziranga National Park (India, about 10%).
GBIF citizen-science records
It is estimated from how often the Pale-chinned Blue-Flycatcher is recorded against all the birds logged in Manas National Park (282 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.
