Inca Tern at the Artis Royal Zoo (also known as Natura Artis Magistra), Amsterdam (Holland)

The Inca Tern is a seabird in the family Sternidae. It is the only member of the genus Larosterna. This uniquely plumaged bird breeds on the coasts of Peru and Chile, and is restricted to the Humboldt Current. It is an erratic, rare visitor to the southwest coast of Ecuador. It can be identified by its dark grey body, white moustache on both sides of its head, and red-orange beak and feet. The Inca Tern feeds primarily on small fish, such as anchovies.
The species spots its prey from the air, diving into the water to grab meals with its pointed beak. Its call is a cat-like mew.
