Land Wild Birds’ Beaks Functions

We all know that birds have beaks or beaks, but because they have teeth to chew their food? Are they beaks or beaks (used interchangeably) for eating purposes only? The answers to these questions are no! All wild bird beaks or perch function in several ways depending on their environment and dietary needs. This article will deal with land birds like songbirds, perching birds and birds of prey etc. although waterfowl and waterfowl follow many of these concepts will be covered in a future article. Bills or beaks come in different shapes and sizes that determine the function it plays in the needs of the wild bird.

The beak of wild birds consists of two bony structures that form the upper and lower mandibles. These structures are enclosed in a thin covering of keratin (protein) formed by epidermal cells that grow from the plates at the base of the mandibles. This sheath is called a rhamphotheca. These cells grow continuously to replace old and worn areas of the bird’s bill. The upper mandible (maxilla) is embedded in the skull. Each side of the skull has a bony tooth that attaches to the maxilla. A nasofrontal hinge allows the top of the beak to move up or down. The lower mandible is attached by two plates that form a U-shaped or V-shaped structure that supports the maxillary bone. Plates attach to both sides of the skull. The jaw muscles allow the beak to close even though they are mostly weak muscles.

Most wild birds have tomia in their mandibles. These are rounded, sharp or saw-toothed cutting edges on the mandibles. This structure helps in cutting seeds, insects or lizards etc. Tomia helps keep prey or a slippery fish from escaping or slipping off the hook.

Wild birds have a tooth in their beak as birds to help break through their shell to come into the world. This disappears after hatching. Ducks and swans have bill nails or horns on their beaks, which are simply layers of keratin that help dig up plants or open shellfish.

In some wild birds, the bill changes color or changes in brightness to attract a mate. Once the breeding season is over, the keratin layer is shed and a new layer or covering replaces it. Puffins are a good example of this phenomenon. The cardinal is a good example of a beak that becomes more vivid to attract a mate.

Bill clapping and dancing to attract a mate is seen in wild birds such as cranes and storks. The birds touch their bills and dance in a mating ritual with their heads bobbing and interacting with each other. If the pair stays in sync, the pair stays together, if not they separate and look for another partner. Bill drumming is used by woodpeckers and hens to attract and find their mates.

When observing birds, note the type and size of the bill compared to the bird’s head and body to help identify the bird you saw. The shape will help classify the type of food the wild bird prefers. The category a wild bird falls into whether it is a seed eater or an insect eater is not always cut and dried because at different times of the year or season birds can switch to what they eat. For example, robins eat mostly worms or grasses in the spring or when raising their young, but when berries become available, they may eat them instead. When worms become harder to find in the fall or winter months, peppercorns will become their staple food. Hummingbirds and orioles drink copious amounts of nectar in the spring, but will eat insects and fruit respectively as the seasons pass.

Basically the beak determines the food the bird prefers and how it gets it. The size and shape of the bill help as a tool in achieving the bird’s goals. Below is a basic general list of the different beak shapes and sizes of wildfowl and their food preferences.

Seed eaters have conical carpels that crush and cut seeds, nuts and pits. The larger, heavier-looking bills belonging to cardinals and grosbeaks handle seeds with larger, harder shells such as sunflower and sunflower seeds, maple pods, and spruce nuts. The smaller conical beaks of finches, buntings and sparrows crush the smallest seeds of grass, millet and thistle.

Nectar eaters possess long, thin, slightly downward-curving straws that enable the hummingbird to reach further into the flower to drink the sugary substance, nectar.

Nectar and fruit eaters tend to have longer and narrower beaks than seed eaters, but shorter than nectar eaters. Red-and-black tanagers, vireos and orioles peck at the fruit of apple, cherry, berry bushes and trees to get their food. The toucan is an exception in bill length with its long colorful bill that enables the bird to reach the avocados and pull them from the tree.

Insectivores have thin, short, pointed beaks that can open their bills wide to catch insects in flight. Their bills are extremely small compared to their heads. Swifts and swallows enjoy their meals in flight.

Test bills are longer and sharper than insect eater beaks. The bills appear thicker and heavier in width, although they are not heavy because most of the beaks are hollow. Robins, snares, and flickers hit the needles, grubs, and insects on the ground with these spiked baits.

Chisel-billed birds often overlap with probe-billed birds. They have long heavy bills that can hammer into tree trunks as well as drill and dig holes. These heavy, yet slightly heavy, bills are quite powerful and allow the bird to drill for insects as well as dig large holes for nesting purposes. The woodpecker family of birds also use their bills to drum for a mate.

Tearing or tearing beaks are very large, heavy-looking beaks with a very sharp hook at the end of the beak. These beaks belong to birds of prey. The family of owls, hawks and eagles use this hook to pierce their prey and kill it. The beak allows the bird to rip or tear prey to pieces. There is a small tooth on the upper mandible that aligns with a space on the lower mandible to hold it in place while the bird is in flight. Vultures also belong to this group, although they do not hunt, but are opportunistic birds that tear and tear carrion.

Although the beaks or beaks of wild birds are similar in many ways, their functions and dietary needs are dictated by the shape and size of their bill. It is necessary to remember that wild birds move into other categories depending on the availability of food in that season. Bills act as tools whether for nest building, mating or play. Jays and crows love to pick up shiny objects and play with them before taking them to her nest. Other birds like to grab threads, animal hair, and materials to weave into their nests or to line the nest. No matter what the job is the beak plays a big role in the life of the bird. Knowing the bill shape helps identify a bird a birdwatcher sees or where a birdwatcher can find a particular bird to add to his or her life list.
