Contents

Description
The Inca tern is a large tern, approximately 40 cm long. Sexes are similar; the adult is mostly slate-grey with white restricted to the facial plumes and the trailing edges of the wings. The large bill and legs are dark red. Immature birds are purple-brown, and gradually develop the facial plumes.
Breeding
The Inca tern breeds on rocky cliffs. It nests in a hollow or burrow or sometimes the old nest of a Humboldt penguin, and lays one or two eggs. The eggs are incubated for about 4 weeks, and the chicks leave the nest after 7 weeks.
Feeding
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.
