It breeds in dense coniferous forest and taiga eastwards from Siberia and Mongolia to Japan. It is strongly migratory, wintering south to China and Southeast Asia. It is a rare vagrant to western Europe.

It nests in trees, laying 4-6 eggs in a neat nest. Migrating birds and wintering birds often form small flocks. It is omnivorous, eating a wide range of insects, earthworms and berries.

From Khonoma village in Nagaland, India.

This is an attractive thrush, with a grey back and head, the latter having a black eyeline, bordered white above and below. The breast and flanks are orange, and the belly white. The sexes are fairly similar, but immatures have a browner back.

The male has a simple whistling song, similar to the related mistle thrush.

In 2007 an eyebrowed thrush was sighted at the Jerusalem Bird Observatory in Jerusalem.[3] This is the second recorded sighting in Israel; the first was at Eilat in October 1996.

In 2011, an eyebrowed thrush was sighted in Australia, near Malanda in Queensland.[4] This is possibly the first confirmed sighting of the species on the Australian mainland.

Fossil record[edit]

In 2017, an assessment of late Pleistocene Indonesian passerines found a fossil of this species.[5]
