    A bird’s beak is technically the external surface of its mouth and is part of the larger structure known as the bill.

    The bill consists of a bony framework, a vascular layer containing blood vessels and nerves, a connective tissue layer that attaches the beak to the bones, and the beak itself, which is the outer sheath covering the jaw bones.

    This outer layer is made of keratin, the same tough protein found in fingernails and horns.

    The bill is divided into 2 parts: the upper portion, or maxillary rostrum, which includes the premaxilla bone and maxillary beak, and the lower portion, or mandibular rostrum, which includes the mandibular bone and mandibular beak.

    Bird nostrils, or nares, are located where the beak meets the head, and many parrots have a fleshy area called the cere that contains the nares.

    Parrot beaks grow continuously from the base beneath the outer keratin layer, which is regularly shed and replaced.

    The bony framework beneath the beak does not grow once matured.

    Depending on the species, beak growth ranges from about 1 to 3 inches per year.

    This growth is balanced by natural wear caused by feeding, grooming, climbing, chewing, and rubbing.

    Healthy birds typically maintain a consistent beak length, while overgrowth often indicates an underlying health issue.
