Pelican

Pelican, large aquatic bird (genus Pelecanus) found in warm climates. The pelican's long bill is provided with an expansible pouch attached to the lower mandible, used not for storage, but simply as a catching apparatus, a scoop-net. Pelicans are social birds, breeding in large colonies. Most species also fish in groups, swimming together, herding the fish in horseshoe formation. All are fine fliers.
