An endemic species refers to a species that is native to where it is found. A species can be endemic to a particular small geographical area, such as a single island, or to a larger area, such as a continent. India has nine hornbill species, of which four are found in the Western Ghats: Indian Grey Hornbill (endemic to India), the Malabar Grey Hornbill (endemic to the Western Ghats), Malabar Pied Hornbill (endemic to India and Sri Lanka) and the widely distributed but endangered Great Hornbill.
