This species does not form large breeding colonies, but it is more gregarious outside the breeding season. It feeds a wide variety of insects that are caught as the martin flies near to cliff faces. It may be hunted by large bats as well as birds of prey, but its extensive and expanding range and large population mean that there are no significant conservation concerns.
The dusky crag martin was formally described by in 1832 as Hirundo concolor by British soldier and ornithologist William Henry Sykes. It was moved... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Dusky Crag Martin is recorded against all the birds logged in Surat (17 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.
