The large blue flycatcher (Cyornis magnirostris) is a medium-sized bird species characterized by distinctive sexual dimorphism along with most others of the Flycatcher family. This species of bird is in the family Muscicapidae. It is found in the eastern Himalayas, from Nepal to Bangladesh. It winters in the northern Malay Peninsula.
Adult male large blue flycatchers' exhibit striking features, including a cold, pale blue forehead. Their lores, cheeks, and some of the ear-coverts are jet black, contrasting with a deep blue cap on their head and dark blue feathers on the wings and tail with a subtle purplish tinge. Males display a vibrant orange-rufous throat and chin, which extends to the rear flanks and mid-belly, with the lower underparts being whitish. The bill is black, and the legs vary in color from pale flesh-pink to pale pinkish gray or light horn-brown. In stark contrast, the females are characterized by their grayish upperparts and crown, and strongly rufous-tinged rump, tail, and edges of the wing feathers. Their facial features include a pale buffish eyeing and lores, with dark brown cheeks and a pale rufous-tinged buff chin and throat. The remainder... Wikipedia →

Rare
Under 5% of wildlife watchers report a Large Blue-Flycatcher sighting in Bangkok on a given day, based on 89 verified sightings from GBIF citizen-science data. It is the 156th most-seen of the 277 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.
November
In that month about 10% of wildlife watchers report a Large Blue-Flycatcher in Bangkok on a given day, against under 5% in December to October, the lowest months. That is one of Bangkok's driest months, with about 40 mm of rain against 280 mm in September.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Large 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.
Only Bangkok, in our data
Bangkok is the only city on Wallace's Line with enough records to rate Large Blue-Flycatcher sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Large Blue-Flycatcher is recorded against all the birds logged in Bangkok (89 verified sightings), 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.
