The scaly thrush (Zoothera dauma) is a member of the thrush family Turdidae. It breeds in dense wet forests in the Himalayas east through southwestern China to northern Indochina, and with disjunct populations (but possibly separate species) on Iriomote Island off southern Japan, and on Sumatra and Java in Indonesia.
The sexes are similar, 27–31 cm long, with black scaling on a paler white or yellowish background. The most striking identification feature in flight is the black band on the white underwings, a feature shared with most other species in the genus Zoothera, and also Siberian thrush in the genus Geokichla. The male has a song which is a loud, far-carrying mechanical whistle, with 5-10 second pauses between each one second long phrase twee...tuuu....tuuu....tuuu.
Three subspecies are currently accepted: Z. d. dauma — Himalayas east to southwest China, south to northern Thailand; a short-distance altitudinal migrant, dropping to foothills in winter Z. d. horsfieldi — Sumatra, Java, Bali, Lombok and Sumbawa; resident

Rare
Under 5% of wildlife watchers report a Scaly Thrush sighting in Dhaka on a given day, based on 34 verified sightings from GBIF citizen-science data. It is the 115th most-seen of the 185 birds we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
February and November
In those months about 10% of wildlife watchers report a Scaly Thrush in Dhaka on a given day, against under 5% in March–October and December–January, the lowest months. Those are among Dhaka's driest months, with about 30 mm of rain a month against 440 mm in July.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Scaly Thrush sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 4 cities where we can rate Scaly Thrush sightings, Dhaka has the highest daily chance: under 5%. Next come Kathmandu (Nepal, under 5%) and Dehradun (India, under 5%).
GBIF citizen-science records
It is estimated from how often the Scaly Thrush is recorded against all the birds logged in Dhaka (34 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
