- Turdus eunomus
Identification
23–25 cm (9-9¾ in)
Male
- Dark brown upperside with some black spots and an obvious rufous wing panel and rump
- Obvious pale supercilium and throat
- malar area pale in male but more contrasting dark and pale in female (not all individuals can be reliably sexed)
- Underside white with dark spots producing a band across upper breast and down flanks
- Underwing almost entirely buffy-rufous

Dusky Thrush has occurred as vagrant in Europe and Britain.
Taxonomy
Dusky Thrush has recently been split from Naumann’s Thrush Turdus naumanni. Hybrids do occur and are not too rare around Beijing3.
Habitat
Breeds in coniferous and broad-leaf forest and scrub.
