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.

Possible
About 30% of wildlife watchers report a Blue Whistling-Thrush sighting in Hong Kong on a given day, based on 897 verified sightings from GBIF citizen-science data. It is the 19th most-seen of the 204 birds we can rate there. Over three days the chance rises to about 70%, and over a week to about 90%, if each day is a fresh chance.
February–March and November–December
In those months about 40% of wildlife watchers report a Blue Whistling-Thrush in Hong Kong on a given day, against about 20% in June–July and September, the lowest months. Those are among Hong Kong's driest months, with about 40 mm of rain a month against 280 mm in June.
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.
Among the best
Of the 24 cities where we can rate Blue Whistling-Thrush sightings, Hong Kong ranks 2nd at about 30%, level with the leaders once rounded. The best odds are in Srinagar (India, about 30%).
Same family: Muscicapidae
The closest relatives of the Blue Whistling-Thrush that you can see in Hong Kong (family Muscicapidae, Old World Flycatchers, Robins, and Chats) are Oriental Magpie-Robin (about 80%), Asian Brown Flycatcher (about 20%) and Daurian Redstart (about 10%), 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 Hong Kong (897 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.
