Where to spot
Breeds in coastal deserts of Peru and Chile, with some colonies far inland. Forages offshore in the Humboldt Current system of the eastern Pacific.
How to spot
Look for its uniformly dark, sooty-brown plumage and shallowly forked tail. Its flight is often direct and strong. Best observed during pelagic trips off the coasts of Peru and Chile.
When to spot
Breeding activity is from May to October. Can be observed at sea year-round in the Humboldt Current, with more regular sightings during the breeding season.
