How does the woodpecker catch insects, and how does the woodpecker catch insects

According to Ivan R., an ornithologist at the University of California, Davis, CaliforniaSchwab), woodpeckers spend most of their time pecking at wood (catching insects) with their pointed beaks. If it were human, the brain and eyes would be severely damaged.

Schwab's research revealed that woodpeckers had evolved a thick, spongy skull that protected the brain like a sponge. Woodpeckers have also evolved their own "harness" system, which closes the transparent membrane of its eyes 1 millisecond before its beak pecks at the trunk, wrapping the eyeballs tightly and preventing them from popping out of their sockets.

How woodpeckers are raised.

1. Habits: There are about 180 200 species of woodpeckers, and they are known for searching for insects in the bark of trees and digging holes in dead wood for nests. Most woodpeckers are resident birds, and a few species have migratory habits.

Most woodpeckers spend their entire lives in the woods, spiraling to climb tree trunks in search of insects; Only a few above-ground foraging species are perched on the branches like passerine birds. Most woodpeckers feed on insects, but some species eat fruits.

2. Growth and reproduction: May is the season for woodpeckers to reproduce. They go around looking for their mates and then mate to lay eggs.

Under normal circumstances, one egg is laid per day, and it takes three eggs in a clutch to hatch. The incubation of eggs is undertaken by the couple in turn, and the eggs are exchanged more than ten times a day. Ten days later, the chicks broke out of their shells.

After a month of feeding, the chicks nest and learn to fly and peck at wood. After 50 days, the chicks leave their parents and begin to live independently.

The woodpecker has two toes facing forward, one to one side and one backward, with sharp claws at the tips of the toes. Woodpeckers have stiff tail feathers that can rest on tree trunks to provide additional support for their bodies. They usually use their beaks to quickly tap on the trunk of trees to find insects hiding within the bark, and when determined, their hard beaks are able to quickly peck a deep hole in the bark and stick out their long tongues like lightning to catch insects.

Summary. Woodpeckers like to eat bugs that hide in the bark of trees and play a role in protecting trees. When it flies to a tree, it claws tightly on the trunk and taps the trunk with its hard beak to check for pests lurking in the trunk, just as a doctor taps the affected area with his hand to identify the disease by listening to the sound.

You are envious, I am glad to answer for you, I have inquired for you: Hello kiss The woodpecker's legs are short and powerful, with two toes in the middle of the toe and two toes backward, and its body structure is very suitable for climbing trees. It has hard tail feathers and a straight, hard mouth, a soft and slender tongue, and a barb at the tip of the tongue that makes it easy to hook out the worms.

Woodpeckers like to eat insects that hide in the skins of trees and play a role in protecting trees. When it flies to a tree, it claws tightly grasps the trunk and taps the trunk with its hard beak to check for pests lurking in the trunk, just as a doctor taps the affected part with his hand to identify the disease by listening to the sound.

Appearance: The woodpecker has a large head, but a long neck, a strong and straight beak, chiseled, a long and telescopic tongue, and a short hook at the apexFeet slightly shorter, with 3 or 4 toes;The tail is flat-tailed or wedge-shaped, and the feathers are hard and elastic, supporting the body when pecking. The skull is lizard-palatinal, the hoe bone is replaced by a number of paired bone fragments, the jaw palatine bone is small and far from the sides, the posterior end of the sternum has 2 incisions on each side, and the sternal stalk is bifurcated.

Leg muscles, insufficiens muscles, and accessory femoraxonus muscles.

Characteristics: Woodpeckers are able to jump between tree trunks and branches with incredible agility. They are able to stand firmly on vertical tree trunks, which is related to the structure of their feet.

With a hard mouth, a long tongue and a hard tail, he lives in the forest and likes to peck wood and catch insects on big treesWoodpeckers are famous forest doctors, and they eat beetles, caterpillars, beetles, beetles, spiders, ants, and other pests.

Woodpeckers are found in Eurasia and northern Africa, including all of Europe, Africa north of the Tropic of Capricorn, the Arabian Peninsula, and the Himalayas, Hengduan Mountains, Minshan, Qinling, and Asia north of the Huai River. Indian Ocean, including the island of Madagas** and its adjacent islands. South-central Africa, including the southern part of the Arabian Peninsula and the entire African continent south of the Sahara Desert (Tropic of Capricorn).

The woodpecker has a very high ability to catch insects, its beak is strong and sharp, not only can peck the bark, but also can peck the hard wooden part, much like a carpentry chisel, its tongue is slender and soft, can stick out of the outside of the mouth for a long time, and there is a pair of very long lingual horn bones, around the outside of the skull, play a special spring role, the flexion of the hyoid bone angle, can make the tongue stretch freely, the tip of the tongue keratinized, there are rows of barbed hooks and mucus, very suitable for hooking insects and larvae on the trunk.

The woodpecker strikes the tree about 500-600 times a day, and the speed of pecking is extremely fast, almost twice the speed of sound, so that its head is inevitably subjected to very violent vibrations, but it has neither a brain nor a headache. It turns out that there are at least three layers of anti-shock devices on the head of the woodpecker, its skull structure is loose and filled with air, and there is a tough outer meningeal inside the skull, and there is a narrow space between the outer meninges and the cerebral medulla, which contains fluid, which reduces the fluid transmission of shock waves and plays a role in shock absorption. Since sudden rotational movements are more likely to cause brain damage than horizontal movements in a straight line, there are well-developed and powerful muscles on both sides of the head, which can play a role in shock prevention and shock absorption.
