The Indian River Tern is a resident breeder along inland rivers of the country. It is almost exclusively found on freshwater, rarely venturing even to tidal creeks. It is a medium-sized tern with dark grey upperparts, white underparts, a forked tail with long flexible streamers, and long pointed wings. The bill is yellow and the legs red. It has a black cap in breeding plumage as seen in this shot. In the winter the cap is greyish white, flecked and streaked with black, there is a dark mask through the eye, and the tip of the bill becomes dusky. As with other Sterna terns, the river tern feeds by plunge-diving for fish, crustaceans, tadpoles and aquatic insects in rivers, lakes, and tanks.
