The Western Ghats biodiversity hotspot in India is threatened by habitat loss and fragmentation, likely to impact large-bodied, wide-ranging species such as hornbills, as well as endemic species with restricted ranges and specialised requirements. In this survey along the Western Ghats, we surveyed for four hornbill species that occur here: Malabar Pied Hornbill and Indian Grey Hornbill (endemic to Indian subcontinent), Malabar Grey Hornbill (endemic to Western Ghats), and the Great Hornbill. The survey recorded all bird species, with special attention to restricted-range species across the Western Ghats.
