Descripción
American White Pelicans are gregarious birds, often associated with Double-crested Cormorants. A flock of migrating American White Pelicans is a majestic sight-a long line of ponderous birds, flapping and coasting. Each bird seems to take its cue from the one in front of it, beginning to flap and starting a glide when its predecessor does. These birds ride rising air currents to great heights, where they soar slowly and gracefully in circles. These birds are more buoyant than Brown Pelicans and do not dive for their food. They cooperate to surround fish in shallow water, scooping them into their pouches. They take in both water and fish, and then hold their bills vertically to drain out the water before swallowing the food. Because of pesticides, human disturbance, and the draining of wetlands, this species is in decline. The number of active colonies has dropped sharply in recent decades.
