High Quality Content by WIKIPEDIA articles! The White's Thrush or Scaly Thrush (Zoothera dauma) is a member of the thrush family Turdidae. It breeds in wet coniferous taiga, mainly in eastern Asia and Siberia. Northern races are strongly migratory, with most birds moving to southeastern Asia during the winter. It is a very rare vagrant to western Europe. It is very secretive, preferring dense cover. There are several races which are now often split into a varying number of separate species. Z. d. aurea (White's Thrush), including the questionable subspecies Z. d. toratugumi, is the migratory Siberian and north-east Asian form. Z. d. dauma (Scaly Thrush) breeds in the Himalaya and migrates to the foothills in winter. Z. d. horsfieldi (Horsfield's Thrush) is resident in Indonesia on the islands of Sumatra, Java, Bali, Lombok and Sumbawa. Z. d. neilgherriensis (Nilgiri Thrush) is resident in the hills of southwest India. Z. d. imbricata (Sri Lanka Thrush) is endemic to the hills of Sri Lanka and is particularly distinctive, being smaller, long-billed and rufous below. Z. d. major (Amami Thrush) is restricted to the Amami Islands in Japan.
