Naumann's thrush (Turdus naumanni) is a species of the thrush family Turdidae which breeds eastwards from central Siberia to North Manchuria, Amurland and Sakhalin. It is closely related to the more northerly breeding dusky thrush T. eunomus; the two have often been regarded as conspecific.
This species breeds in open woodland areas; dusky thrush, as would be expected, is more tolerant of mountainous and tundra-edge habitats. This species is strongly migratory, wintering South Asia to Southeast Asia, principally in China, Korea and neighboring countries. It is a rare vagrant to western Europe.
It nests in trees, laying 3-5 eggs in an untidy but neatly lined nest. Migrating birds and wintering birds often form small flocks. It is omnivorous, eating a wide range of insects, especially mosquitoes, earthworms and berries.
This is a medium-sized but stocky thrush, reminiscent in structure of a small fieldfare. The underwing is reddish brown, and there is a pale supercilium. Naumann's thrush has pale brown back and head. The face, breast, flank spots and rump are reddish, and the belly and undertail are white, whereas dusky thrush has a darker brown back and rump, and the face, breast, and flank spots rump are black. The belly and undertail are white.
The female is fairly similar to the male, but immatures have a weaker patterning. The song of Naumann's thrush may differ from the simple fluted or whistling redwing-like song of dusky thrush. The genus name comes from Latin Turdus, "thrush", and the species and English names commemorate the German naturalist Johann Andreas Naumann. Wikipedia →

Rare
Under 5% of wildlife watchers report a Naumann's Thrush sighting in Suzhou on a given day, based on 32 verified sightings from GBIF citizen-science data. It is the 91st most-seen of the 171 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
February
In that month about 20% of wildlife watchers report a Naumann's Thrush in Suzhou on a given day, against under 5% in April to December, the lowest months.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Naumann's 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.
18th of 23
Of the 23 cities where we can rate Naumann's Thrush sightings, Suzhou ranks 18th at under 5%. The best odds are in Tianjin (China, about 30%), Beijing (China, about 20%) and Seoul (South Korea, about 20%).
Same genus: Turdus
The closest relatives of the Naumann's Thrush that you can see in Suzhou (genus Turdus, Typical Thrushes) are Chinese Blackbird (about 90%), Grey-backed Thrush (about 20%) and Dusky Thrush (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Naumann's Thrush is recorded against all the birds logged in Suzhou (32 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.
