Caspian Tern

Hydroprogne caspia

Description:

It is the world's largest tern with a length of 48–56 cm, a wingspan of 127–140 cm and a weight of 574–782g.[2] Adult birds have black legs, and a long thick red-orange bill with a small black tip. They have a white head with a black cap and white neck, belly and tail. The upper wings and back are pale grey; the underwings are pale with dark primary feathers. In flight, the tail is less forked than other terns and wing tips black on the underside.[2] In winter, the black cap is still present (unlike many other terns), but with some white streaking on the forehead. The call is a loud heron-like croak
