Inca Tern Larosterna inca

With its curling white “mustache” plumes, the Inca tern is easy to identify. It feeds in the cold, nutrient-rich waters of the Humboldt Current, dipping down to the surface to catch small fish. Inca terns often follow sea lions and whales, preying on shoals of fish as they try to escape the larger predators. Inca terns nest among rocks or in abandoned burrows.
