Eurasia : East


Breeds in higher latitudes of east Palerctic, mainly in lowlands from fringe of tundra through taiga and wooded steppe, in riverain woods of willow and poplar, with dense tall bushy undergrowth, also in birch and alder and more rarely in larch along terraces and low scrub. Occurs in thinly wooded regions and on outskirts of forest.


4 to 6 eggs are laid in a nest made of grass, rootlets, and twigs, lined with clay, and built on a tree branch, stump, ground, or cliff ledge. Incubation ranges from 13 to 15 days and is carried out by the female.

Feeding habits

Mostly insects and invertebrates.


This species has an extremely large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). The population trend is not known, but the population is not believed to be decreasing sufficiently rapidly to approach the thresholds under the population trend criterion (>30% decline over ten years or three generations). The population size has not been quantified, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.

Breeds in Siberia east of Yenisey river and Sayan mountains.

Naumanns Thrush status Least Concern


Migratory. North Siberian race, eunomus, migrates through Kuril Islands, Sakhalin, Hokkaido, Korea, Manchuria, and Mongolia to winter in southern Japan, Taiwan, southern China, north-west Thailand, northern Burma, Assam (India), and occasionally Nepal and Pakistan. South Siberian race, nominate naumanni, migrates through Mongolia and Korea to winter in China north to southern Manchuria and south to Yangtse river and in Korea, with a few in Japan and Taiwan.
Recorded chiefly autumn-winter (eunomus more frequently than nominate naumanni).
