Overview
Udhayamarthandapuram Bird Sanctuary is a tank wetland in Tiruvarur district of Tamil Nadu, near Thiruthuraipoondi in the Kaveri delta.
It fills with water in the north-east monsoon and attracts many breeding and migratory waterbirds.
It was designated a Ramsar site in 2022.
The tank covers only about 44 ha but supports large heronries of egrets, cormorants and darters.
Its water comes from the Kaveri canal system and local rain.
Local villagers have long protected nesting birds, as at other Tamil Nadu tank sanctuaries.
It is a good example of a small human-made wetland qualifying under Ramsar criteria.
