Photographer's Note
The Indian River Tern or just River Tern (Sterna aurantia) is a bird in the tern family . It is a resident breeder along inland rivers from Iran east through Pakistan into India and Myanmar to Thailand, where it is uncommon. It does not occur in Sri Lanka. Unlike most Sterna terns, it is almost exclusively found on freshwater, rarely venturing even to tidal creeks.
This species breeds from March to May in colonies in less accessible areas such as sandbanks in rivers. It nests in a ground scrape, often on bare rock or sand, and lays three greenish-grey to buff eggs, which are blotched and streaked with brown.
In non-breeding plumage in Hyderabad, India.This is a medium-sized tern, 38-43 cm long 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. 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.
The sexes are similar but juveniles have a brown head, brown-marked grey upperparts, grey breast sides and white underparts. The bill is yellowish with a dark tip
As with other Sterna terns, the River Tern feeds by plunge-diving for fish, crustaceans, tadpoles and aquatic insects in rivers, lakes, and tanks. Its numbers are decreasing is due to the pollution of their habitat.

It's a realy shame this one has gone without comment yet, Zahoor - what a great moment! You've captured a sense of motion, as you've got some blur in the wings, but the central subjects - the birds' heads and the item (pine needle, maybe?) that they're fighting over are incredibly still. Great DOF at bottom, with the trees in the distance forming a nice natural border, and little rain droplets visible! Outstanding color, though minimal - just an all around excellent piece of work.
