Dusky Thrush
Turdus eunomus · 斑鸫
Introduction
A member of the thrush family breeding from central Siberia to Kamchatka and wintering in Korea, Japan, South China, and Myanmar. It breeds in open woodland, showing greater tolerance for mountainous and tundra-edge habitats than its close relative. The species is strongly migratory.
Description
Medium-sized but stocky, reminiscent in structure of a small fieldfare. The male has a dark brown back and rump, with black spots on the face, breast, flanks, and rump. The belly and undertail are white. A pale supercilium is present, and the underwing is reddish-brown. Females are fairly similar to males, while immatures exhibit weaker patterning.
Identification
Distinguished from the similar Naumann's thrush by its darker brown back and head, whereas the latter has a paler brown back and reddish face, breast, flank spots, and rump. Both share white bellies and undertails. The song is a simple fluted or whistling call, similar to that of the redwing.
Distribution & Habitat
Breeds eastwards from central Siberia to Kamchatka. Winters south to southeast Asia, principally in China, Korea, Japan, and Myanmar. It is a rare vagrant to western Europe, with a recorded sighting in Derbyshire, United Kingdom, in December 2016.
Behavior & Ecology
Nests in trees, laying 3-5 eggs in an untidy but neatly lined nest. Omnivorous diet includes insects (especially mosquitoes), earthworms, and berries. Migrating and wintering individuals often form small flocks.
