Pelicans
Pelicans are distinguishable because they have extremely large bills and expandable throat pouches. They catch fish by scooping water into their pouch. They drain the water and swallow the fish.
Pelicans have a preen gland that secretes oil. They rub this oil on their feathers to waterproof them.
Factoid:
The Memphis Zoo has five pelicans: Radar, Fat Albert, Billie Jo, Bobby Jo and Betty Jo.
