Salim Ali Bird Sanctuary, also known as Thattekkad Bird Sanctuary, is a protected forest in Kerala's Ernakulam district near Kothamangalam. Established in 1983 and named for ornithologist Dr Salim Ali, it covers about 25 square kilometres between branches of the Periyar River. Its evergreen, semi-evergreen, deciduous and riparian habitats support more than 270 recorded bird species.
Early morning is generally the most productive period for observing birds at Salim Ali Bird Sanctuary. Visitors can use designated nature trails and may arrange guided birding or approved boating through local ecotourism services. Quiet clothing, binoculars and suitable walking shoes are recommended. Current entry arrangements, trail availability and seasonal restrictions should be confirmed before travelling, particularly during heavy monsoon weather.
