The Indian blackbird (Turdus simillimus) is a member of the thrush family Turdidae. It was formerly considered a subspecies of the common blackbird. It is found only in India and Sri Lanka. The subspecies from most of the Indian subcontinent, simillimus, nigropileus, bourdilloni and spencei, are small, only 19–20 centimetres (7.5–7.9 inches) long, and have broad eye-rings. They also differ in proportions, wing formula, egg colour and voice from the common blackbird.
The Nilgiri blackbird (T. s. simillimus) is resident up to 2,000 metres in the Western Ghats from Biligirirangans and Nilgiris till about Nelliampathies where it integrates with Bourdillon's blackbird. The black-capped blackbird (T. s. nigropileus) is resident up to about 1,820 metres (5,970 feet) in the Western Ghats of western India and the northern and central parts of the Western Ghats. Some populations migrate further south in winter. The male is brownish slate-grey with a dark cap, and the female is mid-brown, paler below. It is small with a relatively broad yellow eye-ring.

GBIF citizen-science records
It is estimated from how often the Indian Blackbird is recorded against all the birds logged in Horton Plains National Park (427 verified sightings from 2019 to 2026), 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.
