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 Nanjing on a given day, based on 179 verified sightings from GBIF citizen-science data. It is the 27th most-seen of the 162 birds we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
July
In that month about 40% of wildlife watchers report a Blue Whistling-Thrush in Nanjing on a given day, against about 20% in January–February, August and November, the lowest months. That is one of Nanjing's wettest months, with about 240 mm of rain against 40 mm in December.
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, Nanjing ranks 3rd at about 30%, level with the leaders once rounded. The best odds are in Srinagar (India, about 30%) and Hong Kong (China, about 30%).
Same family: Muscicapidae
The closest relatives of the Blue Whistling-Thrush that you can see in Nanjing (family Muscicapidae, Old World Flycatchers, Robins, and Chats) are Oriental Magpie-Robin (about 60%), Daurian Redstart (about 30%) and Red-flanked Bluetail (about 30%), 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 Nanjing (179 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.
