Naumann's thrush

Naumann's thrush (Turdus naumanni) is a member of the thrush family Turdidae which breeds eastwards from central Siberia. 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 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.
