These cells continuously grow to switch old and worn areas of the bird’s bill. The higher jaw (maxilla) is embedded into the os. each side of the os includes a bony projection that attaches to the maxilla. A nasofrontal hinge allows the higher portion of the beak to move up or down. The lower jaw is hooked up by 2 plates forming a U-shape or V-shape structure that supports the jaw bone. The plates attach to either facet of the skull. Jaw muscles permit the beak to shut although they are weak muscles for the most half.
Most wild birds have tomia on their mandibles. These are rounded, sharp or serrated cutting edges on the mandibles. This structure helps slice although seeds, insects or lizards etc. The tomia aid in holding the prey or a slippery fish from escaping or slippy out of the bill.
Wild birds have a tooth on the beaks as hatchlings to assist in breaking their shell to return into the planet. This disappears when hatching. Ducks and swan have bill nails or bill horns on their beaks that are merely layers of keratin that help in digging up plants or gap shellfish.
In some wild birds the bill changes color or varies in brightness to draw in a mate. Once the breeding season is over the scleroprotein layer sheds off and a replacement layer or covering replaces it. Puffins are a decent example of this phenomena.

eaters tend to possess longer and narrower beaks than the seed eaters however shorter than the nectar consumption birds. Scarlet tanagers, vireos and orioles eat the fruit of apple, cherry, berry bushes and trees to get their food.
