The flightless cormorant is one of the most unusual and rarest of the sea birds in the Galapagos. Their total distribution is limited to a few sites on Fernandina and Isabela. Cormorants, which are related to boobies, frigatebirds, and pelicans, are generally good fliers, but the species in the Galapagos, in the absence of predators, has exchanged the ability to fly for better swimming ability. They retain, nonetheless, a trademark characteristic of cormorants. Upon leaving the water, they extend their wings to dry, revealing small wings with scraggly feathers. Adult Galapagos cormorants have striking blue eyes.
