The Japanese thrush (Turdus cardis) is a species of bird in the thrush family Turdidae. The species is also known as the grey thrush or the Japanese grey thrush. The species was once split into two subspecies, with birds breeding in China being treated as the subspecies T. c. lateus,, but today differences are attributed to natural variation and the species is treated as being monotypic.
The Japanese thrush is migratory. It breeds in central China and Japan, arriving in Japan by April or May; it winters in coastal southern China (including Hainan) and northern Laos and Vietnam leaving its breeding grounds around October. It occasionally turns up as a passage migrant in Taiwan, and has been vagrant in Thailand. The species is usually found in forests and woodlands, either deciduous or mixed deciduous and coniferous in its breeding habitat, but also secondary forest and even gardens and parks.
The Japanese thrush is a mid-sized thrush. The two sexes have different plumage (sexual dimorphism). The male has a black head, breast, back, wings and tail, and a white underside with black spots in the upper belly and flanks. The legs, bill and thin eye-ring are yellow. The female is brown above and has a white throat, breast and belly, washed with rusty orange on the flanks and black spots.
The Japanese thrush feeds on the ground, scratching through leaf-litter to find insects and earthworms. It will also take fruit. It lays 2-5 eggs in a nest made of twigs and moss, bound with mud and lined with hair and rootlets. The eggs are incubated for 12–13 days and the chick nestling period is 14 days. The species double broods (raising two broods a season), with the female laying a new clutch soon after the first brood fledges. Wikipedia →

Rare
Under 5% of wildlife watchers report a Japanese Thrush sighting in Osaka on a given day, based on 73 verified sightings from GBIF citizen-science data. It is the 93rd most-seen of the 180 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.
April
In that month about 10% of wildlife watchers report a Japanese Thrush in Osaka on a given day, against under 5% in May to March, the lowest months.
Between 4 and 7 am
Across all the parks we cover, that three-hour window holds the most Japanese Thrush sightings with a recorded time, and about half of them come between 6 pm and 6 am: it is most active around dawn and dusk.
19th of 25
Of the 25 cities where we can rate Japanese Thrush sightings, Osaka ranks 19th at under 5%. The best odds are in Changsha (China, about 20%), Wuhan (China, about 20%) and Hong Kong (China, about 10%).
Same genus: Turdus
The closest relatives of the Japanese Thrush that you can see in Osaka (genus Turdus, Typical Thrushes) are Dusky Thrush (about 20%) and Pale Thrush (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Japanese Thrush is recorded against all the birds logged in Osaka (73 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.
