It can hold three gallons of fish and water. Pelicans hold the water in their bill and let it drain off before swallowing the fish. They usually carry fish in the gullet, rather than the pouch. This pouch also helps the bird disperse body heat in warm weather. They can eat four pounds of fish a day.
Pelican tracks show four toes, with one pointing behind.
All toes are joined by a web of skin. This is called a totipalmate foot. The pelican diet consists mostly of fish, but they do eat crustaceans. Gull and pelican tracks. Quarter in middle of picture for size comparison.
