The color of a bird's beak results from concentrations of pigments—primarily melanins and carotenoids—in the epidermal layers, including the rhamphotheca. [75] Eumelanin , which is found in the bare parts of many bird species, is responsible for all shades of gray and black; the denser the deposits of pigment found in the epidermis, the ...

Rostrum (from Latin rostrum, meaning beak) is a term used in anatomy for several kinds of hard, beak-like structures projecting out from the head or mouth of an animal. Despite some visual similarity, many of these are phylogenetically unrelated structures in widely varying species.
The black-and-yellow tropical bird stares curiously into the camera overlooking a section of road near Auckland, New Zealand’s largest city, its beak open as it appears to squawk loudly.
Preening is a maintenance behaviour found in birds that involves the use of the beak to position feathers, interlock feather barbules that have become separated, clean plumage, and keep ectoparasites in check. Feathers contribute significantly to a bird's insulation, waterproofing and aerodynamic flight, and so are vital to its survival ...
Toucan beaks are responsible for only one twentieth of the entire mass of the creature allowing the bird to fly even with its massive beak. [12] As previously mentioned, the keratin shell and closed-cell foam organization in the toucan beak plays a role in the beak's characteristic energy absorption, compressive resistance, high stiffness and ...
