What does a beak look like?

A beak is the hard, pointed projection that forms the mouth of a bird. It is made up of keratin, the same protein found in human fingernails and hair, and is used for a variety of purposes, including eating, drinking, preening, and climbing. Beaks come in a wide variety of shapes and sizes, depending on the species of bird, and are adapted to the specific needs of each bird. For example, hummingbirds have long, thin beaks that are perfect for sipping nectar from flowers, while eagles have powerful, hooked beaks that are ideal for tearing apart flesh. Beaks are also important for birds in terms of communication, courtship, and defense.
