The short-eared owl (Asio flammeus) is a widespread grassland species in the family Strigidae. Owls belonging to genus Asio are known as the eared owls, as they have tufts of feathers resembling mammalian ears. These "ear" tufts may or may not be visible. The short-eared owl will display its tufts when in a defensive pose, although its very short tufts are usually not visible. The short-eared owl is found in open country and grasslands.
The short-eared owl was formally described in 1763 by the Lutheran bishop Erik Pontoppidan under the binomial name Strix flammea. The specific epithet is from the Latin flammeus meaning "flammulated" or "flame-coloured". This owl is now placed with seven other species in the genus Asio that was introduced by the French zoologist Mathurin Jacques Brisson in 1760. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Short-eared Owl is recorded against all the birds logged in Vasai-Virar (12 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.
