The blue whistling thrush (Myophonus caeruleus) is a bird in the Old World flycatchers family Muscicapidae that is found in the mountains of Central Asia, South Asia, China and Southeast Asia. It is known for its loud human-like whistling song at dawn and dusk. The widely distributed populations show variations in size and plumage, with six subspecies accepted. Like others in the genus, they feed on the ground, often along streams and in damp places, foraging for snails, crabs, insects, and fruit.
The blue whistling thrush was formally described in 1786 by the Austrian naturalist Giovanni Antonio Scopoli under the binomial name Gracula caerulea. The specific epithet is from Latin caeruleus meaning "blue". Scopoli based his account on "Le Merle blue de la Chine" that had been described and illustrated in 1782 by the French naturalist Pierre Sonnerat in his book Voyage aux Indes orientales et a la Chine. The type locality has been restricted to Canton. The blue whistling thrush is now one of nine species placed in the genus Myophonus that was introduced in 1822 by the Dutch zoologist Coenraad Jacob Temminck.

Likely
About 50% of wildlife watchers report a Blue Whistling-Thrush sighting in Namdapha National Park on a given day, based on 677 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 9th most-seen of the 298 birds we can rate there. Over three days the chance rises to about 90%, and over a week to over 90%, if each day is a fresh chance.
November to February
In those months about 50% of wildlife watchers report a Blue Whistling-Thrush in Namdapha National Park on a given day, against about 30% in April and October, the lowest months. Those are among Namdapha National Park's driest months, with about 50 mm of rain a month against 660 mm in July. June to September have too few records to rate.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Blue Whistling-Thrush sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
5th of 17
Of the 17 parks where we can rate Blue Whistling-Thrush sightings, Namdapha National Park ranks 5th at about 50%. The best odds are in Langtang National Park (Nepal, about 70%), Doi Inthanon National Park (Thailand, about 60%) and Royal Manas National Park (Bhutan, about 50%). All parks ranked.
Same family: Muscicapidae
The closest relatives of the Blue Whistling-Thrush that you can see in Namdapha National Park (family Muscicapidae, Old World Flycatchers, Robins, and Chats) are Slaty-backed Forktail (about 50%), White-capped Redstart (about 40%) and Plumbeous Water Redstart (about 40%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Blue Whistling-Thrush is recorded against all the birds logged in Namdapha National Park (677 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.
