The Inca Tern is a characterised by his fine moustache (also sported by the females). His range extends along the Humboldt current, on the western side of South America. Here he soars on air currents, scanning the waters for small fish - such as anchovies - on which to feed. Once sighted, he will drop into a dive, striking the water and seizing the prey in his sharp beak. Nests are built on steep cliffs, in burrows and fissures, including the abandoned nests of Humboldt penguins.
