The grey-winged blackbird (Turdus boulboul) is a species of Turdus in the thrush family, found at in the mountains of southern and eastern Asia from the Himalayas to northern Vietnam. Its natural habitat is in the middle altitudes of subtropical or tropical moist montane forests, mostly at 1800–2700 m altitude, but occasionally down to 1200 m in winter, and as high as 3300 m in summer.
It is a large thrush, 28–29 cm long and 88–111 g weight, with distinct sexual dimorphism in plumage. The males are black with faint pale fringes on the belly, and a broad grey patch on the wing covert, secondary, and tertial feathers, somewhat reminiscent of a ring ouzel but more uniformly grey. The females are a plain brown, with only a hint of paler brown on the wings where the males have their grey patch. The bill is bright yellow in males, dull yellow to brownish in females. Both sexes also have a narrow eye ring, yellow in males and greyish in females. Wikipedia →

Rare
Under 5% of wildlife watchers report a Gray-winged Blackbird sighting in Srinagar on a given day, based on 8 verified sightings from GBIF citizen-science data. It is the 101st most-seen of the 120 birds we can rate there. Over three days the chance rises to under 5%, and over a week to about 10%, if each day is a fresh chance.
January and November
In those months about 10% of wildlife watchers report a Gray-winged Blackbird in Srinagar on a given day, against under 5% in February–October and December, the lowest months.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Gray-winged Blackbird sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 3 cities where we can rate Gray-winged Blackbird sightings, Srinagar ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Dehradun (India, under 5%).
GBIF citizen-science records
It is estimated from how often the Gray-winged Blackbird is recorded against all the birds logged in Srinagar (8 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.
