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.
Flightless Cormorant
89–100 cm. Dark brown; vestigial wings unsuited for flight; bright turquoise eyes. Endemic to Galapagos Islands (Fernandina and Isabela). Only flightless cormorant; Vulnerable with about 1,000 pairs. Feeds on fish and octopus by diving near shore; no natural land predators historically.
