Spotted
The Guanay Cormorant is a medium-sized cormorant endemic to the highly productive Humboldt Current system off western South America. It is characterized by its white neck and belly, and greenish-black upperparts.
Where to spot
Endemic to the Pacific coast of Peru and northern Chile, breeding on offshore islands. Its range is tied to the cold, nutrient-rich waters of the Humboldt Current.
How to spot
Look for its clean white neck and underparts contrasting with a greenish-black back and wings. Its pinkish facial skin is also distinctive. Often seen in enormous flocks, fishing actively in coastal waters or densely packed on guano islands.
When to spot
Can be observed year-round along the coasts of Peru and Chile. Breeding activity often peaks during the austral summer, but continuous breeding can occur.
This species is historically one of the most important guano-producing birds, forming immense colonies that contribute significantly to the natural fertilizer industry.
