Woodpeckers can accurately find the hiding place of pests by tapping the trunk with their long mouths. The mouth pecked open the bark, cut a hole and inserted it directly into the nest in the wood. Stick out your long tongue like an earthworm. It is an elastic connective tissue connected with the base of tongue. This extended part comes out from under the maxilla, extends upward around the posterior skull, and enters the right nostril in front of the top of the brain for fixation.
When the root of the tongue slips out of the woodpecker's jaw, the tongue can stretch out very long. There is a colloidal liquid on the tongue that can stick to insects.
If the nest passage is curved or the wormhole is deep and the woodpecker's long tongue can't reach it, he will use the sound wave harassment tactics. After it detects the wormhole, it hits it with its suffocating beak, either down or left or right, making the pores of the trunk sing, and the insects hiding inside feel attacked on all sides and flee everywhere, which gives woodpeckers a chance to search.
Woodpeckers eat pests, hide in the depths of trees and beat them to death. Woodpeckers can take it out of the trunk and dispose of it. Woodpeckers are called "forest doctors" because their staple food is pests, which is very beneficial to prevent and control forest pests and develop forestry.

Application of Woodpecker in Bionics
Woodpeckers have at least three layers of shock-proof devices on their heads, and their skulls are loose and full of air. There is also a tough outer meninge inside the skull, and there is a narrow gap between the outer meninge and the brain marrow, which contains liquid, which reduces the liquid transmission of shock waves and plays a role in shock absorption.
Because sudden rotational movement is more likely to cause brain damage than linear horizontal movement, it has developed and powerful muscles on both sides of its head, which can play a role in earthquake prevention and shock absorption. This exquisite shockproof setting principle provides a safe sports protective cap and shockproof helmet for shockproof engineering and provides a useful reference.
Modern protective caps all have a hard shell with a soft cover inside, and there is a certain gap between them, and a protective ring is added in the cap to prevent the rotational movement when suddenly colliding.
