Favus

    Favus or woodpecker is a bird woodpecker of the most famous bird species which is characterized by a set of characteristics .. where his habits performed regularly and the insistence of strangers also features beak Madab used by the pry trees by the rapid continuous clicking as this bird has a trail solid used with his feet in install itself on the trees and feeds woodpecker on worms and beetles and builds its nest in a strange way as digging a hole in the tree.Then dig a long corridor perpendicular to the entrance hole in the trunk of the tree and a length of 30 cm and at the bottom of this corridor put female woodpecker eggs from 4-7 small eggs. The same old trees or dead forest best suited for woodpeckers environment where wandering find insects and worms, which are abundant in those trees. There are different sizes of birds woodpecker begins each length of up to 7 inches. Featuring male woodpecker spread of red feathers on their heads frequently than females.    
                                                                                                                                                                     Woodpecker feeds on insects and larvae that disappear in the trunks of trees and dig it by clicking. These birds dig their nests in the trees right skill comparable to the skill of the greatest artists of drilling. Woodpecker can Almrakec that clicks between nine to ten clicks per second and getting this number to reach between 1520 when the smaller ones and European green woodpecker species.

Exposed woodpecker during the click of the trees of the upper beak to a big shock, however there has two mechanisms to absorb this shock: The first is a fibrous tissue hyphen between the skull and beak, which alleviate second shock: is San bird spins tongue inside the skull connects with the introduction of the bird. Mechanical resemble that operate accordingly Slingshot tongue muscle, which contributes to ease the shock of each click and thus decreasing the shock (absorbed by the sponge cells) to fade in the end

                                                                                                             When the European green woodpecker nest digging the speed of his work up to 100 km / h this speed does not affect the brain, which has a volume of a cherry. The time interval between the fovea and the other is less than 1/1000 of a second. When the bird starts at the click of the head and beak is organized in a completely straight line, any slight deviation would lead to the rupture in the brain. The trauma caused by these successive roads are no different from those caused by hit in the head by a concrete wall, but the miraculous design of the brain Woodpecker protect him from exposure to any kind of injury.

 

   Related to the bones of the skull when most birds together and works beak with the jaw movement. However, the bird's beak and skull Woodpecker separated from each spongy tissue absorbs shocks resulting from the process of clicking. The result of this flexible material work better than the damper in the car.

    The quality of this article comes from the ability to successive shocks very short commas absorption and restored to normal immediately which exceeds their high quality materials created by modern technology by far. This process will be completed even in cases of bird ten roads performance in the second. The separation of the beak from the skull of this extraordinary method allows for a room that holds the bird's brain to move away from the upper beak during the process of clicking and thus be formed and a second mechanism in the shock absorber.
