how do pelicans catch fish
Some beaks are big, with the ability to get bigger. For example, the pelican has a pouch-like beak it can expand when it's trying to scoop up fish. Brown Pelicans are known for diving into the water to catch fish. However, American White Pelicans float on the surface and scoop up fish as they swim by. The pouch on the pelican's lower bill is usually folded up, but it can get bigger when the bird is fishing. A pelican's pouch can hold three gallons of water. During a typical fishing trip, the pelican will start by filling its expanded pounch. The pouch then contracts, and the water drains out.
