Galapagos brown pelicans are found throughout the Galapagos Islands, skimming over water, plunge-diving and resting in mangrove trees. Brown Pelicans measure around 41 inches in length and have a wingspan of 90 inches. The Galapagos population of the Brown Pelican is said to be an endemic (unique) subspecies of the Pelican Bird. Adult Brown Pelicans can be distinguished from their infants by their plumage. Adults have a white neck, grey-brown upper body and brown/black lower body.
