How to recognize it

Medium-large tern with pale grey upperwings and white underparts
Black shaggy crest/cap; winter adults show a whiter forehead
Long thin black bill with a yellow tip
Loud grating call, like kear-ik or kerr ink

The Sandwich Tern looks pale and neat, with a slim black bill tipped in yellow and a black shaggy crest at the back of the head. In flight it reads as a very light, airy shape with long wings and quick, easy movement.

It is loud and restless around the colony, with constant calling and tight spacing between nests. It feeds by plunge-diving from the air, mostly on small fish, and also takes marine worms, molluscs, and insects.

It favours coasts, small islands, and shallow waters with plenty of food. In Central Europe it is present from March to September, then moves to wintering grounds around the coasts of Africa, India, and Sri Lanka.
