Most birds' bills are specialized for the type of food they eat, such as thick, conical bills for cracking seeds, hooked bills for dismembering prey or spatulate bills for filtering water for aquatic plants and insects.

In addition to feeding, birds also use their bills to carry items such as nesting materials or food to cache, and the bill is essential for preening. Some birds will also use their bills in courtship rituals or to carve out cavities for nesting.
