Uniquely, white pelicans do not dive to catch fish, unlike their brown pelican cousins. Instead, they hunt in groups, forming semicircles and driving fish closer to the banks for catching in shallow water. White pelican's large bill pouch acts as a fishing net for capturing their prey. Brown pelicans, in contrast, hunt by climbing high in the air and dive plunging into the water, headfirst, to catch their fish. Show more
