About These Birds
Great Cormorant
The great cormorant is one of the most widespread seabirds in the world. Unlike most waterbirds, cormorants lack fully waterproof plumage, leading to the iconic pose of standing with wings spread open to dry. In Asia, cormorants have been used by fishermen to catch fish for over a thousand years.
Red-legged Cormorant
71–76 cm. Slender; grey body; red legs; spotted white scapulars; red facial skin; yellow bill. Coastal endemic of western South America (Peru, Chile). Near Threatened; restricted to rocky coasts with Humboldt Current upwelling. Feeds on fish by diving in cold, productive inshore waters.
