The dark-sided thrush (Zoothera marginata) is a species of bird in the thrush family Turdidae. It is also known as the lesser brown thrush, the long-billed ground-thrush, and the dark-sided ground-thrush. The species is monotypic (lacking subspecies) and is closely related to a number of thrushes in the genus Zoothera, including the long-billed thrush and the widespread scaly thrush. It was described by Edward Blyth in 1847 based upon a specimen collected in Rakhine in Burma (Myanmar).
The dark-sided thrush is 24 to 25 cm (9.4–9.8 in) in length and weighs around 80 g (2.8 oz). It has a particularly long blackish bill and the plumage is a contrasting dark brown head with rufous-brown wings. The face has a white loral stripe and a white eyering with a whitish throat and chin. The call is a series of monotone thin whistles.
The species has a discontinuous distribution in the eastern Himalayas, and then a population in the higher areas of Burma, northern Thailand, Laos, Vietnam and the extreme south of China. The species is generally non-migratory but will move down from higher altitudes in winter, and has turned up as a vagrant in Bangladesh... Wikipedia →

Rare
Under 5% of wildlife watchers report a Dark-sided Thrush sighting in Kathmandu on a given day, based on 14 verified sightings from GBIF citizen-science data. It is the 265th most-seen of the 312 birds we can rate there. Over three days the chance rises to under 5%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Dark-sided Thrush in Kathmandu on a given day, so our monthly data shows no clear season.
Between 3 and 6 pm
Across all the parks we cover, that three-hour window holds the most Dark-sided 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.
Only Kathmandu, in our data
Kathmandu is the only city on Wallace's Line with enough records to rate Dark-sided Thrush sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Dark-sided Thrush is recorded against all the birds logged in Kathmandu (14 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.
