Karaivetti Bird Sanctuary

Karaivetti Bird Sanctuary is a large freshwater inland lake and protected bird sanctuary located at Karaivetti in Ariyalur District, Tamil Nadu. Covering about 453.7 hectares, it is one of the largest inland wetlands in the state and an important wintering ground for migratory waterbirds. Notified as a bird sanctuary in 1999 and designated as a Ramsar Site in 2024, it is fed by the Pullambadi canal and supports diverse resident and migratory avifauna.

Visitors can expect a large shallow freshwater lake surrounded by agricultural fields with open water, reed beds and scattered trees. Birdwatching is the main experience from earthen bunds and watchtowers overlooking the lake. Large flocks of waterbirds including pelicans, herons, egrets, cormorants, ducks and migratory species such as Bar-headed Goose can be seen in season. The setting is rural and quiet with basic visitor infrastructure.

The wetland was originally formed as a large irrigation tank fed by the Pullambadi canal system. It was declared as Karaivetti Bird Sanctuary in 1999 by the Government of Tamil Nadu to protect its avifauna. In 2024 it was designated as a Ramsar Site, recognizing its international importance as a wetland ecosystem.
