Consider the short delicate beaks of kinglets, long stabbing beaks of Anhingas, chisel-like beaks of woodpeckers, sharply hooked beaks of raptors for tearing and similar beaks of parrots to crush large nuts. Physical Characteristics. These birds systematically search the deep furrows in the trunks of large trees, and capture any insects they find with their beaks. Birds are a very diverse group of animals, and this is epitomized best by the staggering array of beaks they possess. This musculotendinous tissue serves as an attachment site for the muscles around the throat and tongue…[and] encompasses the head…This feature, not seen in other birds, aids the woodpecker in extending its tongue in order to evenly distribute [the impact] from drumming and to reinforce the head—in other words, the hyoid bypasses the vibrations generated from drumming. To deal with this, some species have very long, sticky-tipped tongues that can fish out the insect. [Another shock-absorbing] feature is a hyoid which rigidly supports the tongue. Seeds that can't be swallowed by a tufted titmouse (Baeolophus bicolor) are taken to a perch where the enterprising bird will repeatedly smash the seed with his stout beak. Though the beaks of woodpeckers are good at making holes in the wood and bark of a tree, the beaks aren't especially helpful for extracting an insect from the hole. by Adelheid Fischer; a portfolio by David Goodsell; Interview with Annick Bay; and Envisioning Biomimicry Through an Ontological Lens by Colleen K. Unsworth, Thibaut Houette, Sarah J. McInerney, Austin M. Garner, and Peter H. Niewiarowski. woodpeckers (and other birds) do break and crack their beaks. Two species of three-toed woodpeckers make up the genus Picoides: the northern three-toe (P. tridactylus), which ranges across the subarctic Northern Hemisphere and south in some mountains, and the black-backed three-toe (P. arcticus), found across forested central Canada.. Once forces reach the hard bone, the upper beak intersects with a thin bone surrounding the skull called the hyoid bone (read more here). This small bird features a very thin, curved beak. When the woodpecker’s beak strikes an object, the high impact force at its tip is relieved by the anatomy of its beak and the spongy hyoid bone. This bird therefore has…relatively little CSF, thereby reducing the transmission of the mechanical excitations into the brain through the CSF (May et al 1976a, 1976b, Schwab 2002).” (Yoon and Park 2011:3). In this issue: What Forces are at Work Here? Diagram representing the uneven lengths of the inner and outer beaks of the M. aurifrons. As these predators often capture animals larger than they can swallow, they use their beaks to rip prey into manageable sized pieces. Click/tap images for attribution and license information. Check out these related strategies that collectively protect the woodpecker’s brain from impact: “The woodpecker’s beak…is a specialized chisel effective in cutting into a tree; unlike a human-made chisel, the beak is self-sharpening…; the beak, made of elastic material, is relatively large compared to the body. It has the size and shape of a sapsucker. The lower beak is also made of stronger bone to help absorb impact. As a result, the stress force from the impact is reduced two to eight times from the beak tip to the point where the beak meets its skull. ALL RIGHTS RESERVED. This site uses Akismet to reduce spam. Animals That Use Their Tongues to Get Food. How Can a Bird's Beak Tell You Where It Lives? The exterior layer is the first to encounter any impact forces. Permission given by illustrator for use on Ask Nature. Illustration by Allison Miller. The different size and shapes of bird beaks, or bills, helps each bird species feed on different foods. When the beak strikes a surface, the majority of forces will travel along the upper beak where they will reach the hyoid bone. Woodpeckers (family Picidae) have sturdy, pointed beaks that allow them to chisel into wood and bark. The Woodpecker is a group of birds in the Picidae family. The woodpecker has a tough, pointed beak which it uses to chip on bark, drum on trees, and find insects. The males have a red crown and … This diagram illustrates the diversion of forces by the lower, inner beak. A woodpecker’s skull is like an internal bike helmet to keep its brain from getting hurt. Species of woodpeckers, such as the golden-fronted woodpecker, drum with their beak to establish their territories and attract mates.
