The globally acclaimed bird sanctuary of Thattekkad, made up of evergreen, deciduous forests and grassland patches, is home to a population of over 500 species of exotic birds. It is to Dr. Salim Ali, the internationally renowned ornithologist, that this microcosm of India's bird population owes much of its fame. His efforts were instrumental in the formation of this sanctuary. Rare birds like the Crimson-throated Barbet, Bee Eater, Sun Bird, Shrike, Black-winged Kite, Night Heron, Falcon, Grey Jungle Fowl, White-breasted Water Hen, Hornbill, Ceylon Frogmoth, Rose-billed Roller and Blue-winged Parakeet live here.
