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 →

Rare
Under 5% of wildlife watchers report a Pale-chinned Blue-Flycatcher sighting in Royal Bardia National Park on a given day, based on 9 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 197th most-seen of the 233 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.
January
In that month about 20% of wildlife watchers report a Pale-chinned Blue-Flycatcher in Royal Bardia National Park on a given day, against under 5% in February–July and September–November, the lowest months. That is one of Royal Bardia National Park's driest months, with about 35 mm of rain against 590 mm in July. August has too few records to rate.
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.
5th of 6
Of the 6 parks where we can rate Pale-chinned Blue-Flycatcher sightings, Royal Bardia National Park ranks 5th at under 5%. The best odds are in Manas National Park (India, about 20%), 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 Royal Bardia National Park (9 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.
