As of 2021, some 350 species of bird have been recorded in the wild on the Isle of Man, a self-governing island in the Irish Sea between Great Britain and Ireland. Over 100 species breed there, including significant populations of red-billed chough, peregrine falcon and hen harrier. The English names are those recommended by the International Ornithological Congress (IOC). Species marked as A are those for which the Manx Ornithological Society (MOS) requires a written description in order to accept a record.
