Description
The beak, bill, or rostrum is an external anatomical structure of birds that is used for eating, preening, manipulating objects, killing prey, fighting, probing for food, courtship and feeding young. The terms beak and rostrum are also used to refer to a similar mouth part in dinosaurs, cephalopods, cetaceans, billfishes, pufferfishes, turtles, tadpoles and siren salamanders.
Although beaks vary significantly in size, shape, color and texture, they share a similar underlying structure. Two bony projections—the upper and lower mandibles—are covered with a thin keratinized layer of epidermis known as the rhamphotheca. In most species, two nostril cavities known as nares lead to the respiratory system.
