The Thattekkad Bird Sanctuary, covering an area of barely 25 km2, and located about 12 km from Kothamangalam (Kerala state, India), was the first bird sanctuary in Kerala. Salim Ali, one of the best known ornithologist described this sanctuary as the richest bird habitat on peninsular India.[1] Thattekkad literally means flat forest, and the region is an evergreen low-land forest located between the branches of Periyar River, the longest river in Kerala.
