Vaduvur Bird Sanctuary

Vaduvur Bird Sanctuary is a protected wetland bird sanctuary centered on the Vaduvur Lake in Vaduvur village, Tiruvarur District, Tamil Nadu. Established in 1999 and covering about 128 hectares, it is an important wintering ground for migratory waterbirds. The sanctuary attracts thousands of birds including herons, ibises and migratory ducks from November to April, and features watchtowers for birdwatching amid paddy fields and rural landscape.

Visitors can expect a large shallow irrigation lake surrounded by paddy fields with watchtowers and elevated viewpoints for observing birds. The setting is quiet and rural with open water, marshy edges and scattered trees. During migratory season, large flocks of waterbirds, herons, egrets, ibises, cormorants and ducks can be seen. Facilities are basic, focused on birdwatching and photography from designated points.

Vaduvur Lake is a large man-made irrigation tank that has long served agricultural needs in the Cauvery delta. Due to its importance for migratory birds, the Government of Tamil Nadu declared the lake and surrounding area as Vaduvur Bird Sanctuary in 1999, covering 128.4 hectares, to protect the wetland ecosystem and avian diversity.
