Udayamarthandapuram Bird Sanctuary

Udayamarthandapuram Bird Sanctuary is a protected wetland bird sanctuary located in Udayamarthandapuram village in Muthupet Taluk of Tiruvarur District, Tamil Nadu. Centered on a large irrigation tank fed by the Muthupet lagoon system, it covers about 0.45 sq km and was notified as a bird sanctuary in 1999. It is notable for seasonal congregations of migratory waterbirds including openbill storks, pelicans, and herons.

Visitors can expect a shallow freshwater irrigation tank surrounded by agricultural fields and scattered trees serving as nesting and roosting sites. The sanctuary is an open wetland landscape with bunds and a watchtower for observation. During migratory season, large flocks of waterbirds can be seen wading, nesting and feeding. Facilities are basic and the experience is focused on quiet birdwatching and photography in a rural setting.
