1. Morphological characteristics: the mouth is as straight as a chisel; tongue long and retractable, apex lined with short hooks; Unlike other birds, which stand on branches, it climbs on upright trunks.

2. Its feet are slightly shorter, its tail is flat or wedge-shaped, most of its tail feathers are 12, its tail is wedge-shaped, and its feather shaft is hard and elastic, supporting its body when pecking wood. In this way, the woodpecker can firmly grasp the trunk of the tree so that it does not slide down, and can also jump on the trunk, move quickly along the trunk, jump upwards, backwards downwards, or crawl in circles to the sides.

3. The woodpecker's tongue goes around the back of the skull and reaches the tip of the beak from the nostrils. This special structure allows the tongue to stick out very long and stretch easily. At the same time, a short hook is formed at the tip of the tongue, which is conducive to hooking and feeding on borers in trees.

I think it's a pest bird. Because it destroys the place where the trees transport nutrients, and then leads to the death of the trees, which is not good for the environment.

It is a beneficial bird, because the food of the woodpecker is the pest, the woodpecker eats the pests on the tree, and the woodpecker can help the tree clean up the pests.

Beneficial birds. Because woodpeckers are an indispensable member of the ecosystem and can maintain the stability of the ecological environment, they are beneficial birds.

There is no absolute distinction between good and bad birds in nature, and both good and bad need to be based on "people-oriented". Beneficial birds, or forest doctors, are a title artificially given by humans to find that woodpeckers are helpful in suppressing forest pests in the ecosystem. Because pests are harmful to human beings, but forests are of great significance to human beings, related to human livelihoods, and woodpeckers help human beings in a sense.

Compared with beneficial birds, pest birds are only birds that are harmful to agricultural production.

Woodpeckers are pest birds, they not only peck at the wood to suck the sap from the trees, but also eat the brains of the chicks!!

When there is a shortage of food, the woodpecker will also target the young birds of other birds, and the woodpecker will take advantage of the absence of the other parent, sneak into the nest, and start pecking the young on the spot, sucking the brain marrow.

In primary school textbooks, we have learned that woodpeckers are pests and pests, and they are the doctors of trees, so woodpeckers are beneficial birds, and if they peck at a certain tree, it means that there are pests in the tree, and the tree is sick, so is this really the case? Is a woodpecker a non-beneficial bird? Now people's cognition has begun to refresh and they have begun to doubt the true identity of the woodpecker.

The woodpecker often inhabits forests and is a bird that feeds on forest pests, such as beetles, gidding insects, and moths in trees. There are more than 200 species of woodpeckers, large and small, among which green woodpeckers and spotted woodpeckers are widely distributed in China. When a person is sick, he is healed by a doctor, and when a tree is sick, he is healed by a woodpecker that feeds on pests.

Woodpeckers can eliminate 1,500 pests every day, so woodpeckers are known as the doctors of the forest, and they are naturally known as beneficial birds.

So is the woodpecker really saving the tree? Still hurting trees? In woodpecker forests, many woodpeckers are pecking at trees, but woodpeckers are not as selfless as humans think.

WhileWoodpeckers don't peck at trees to cure trees, it's just a way for woodpeckers to forage for food. In order to catch pests in the trees, woodpeckers will persistently peck at the trees. In fact, to be sensible, the relationship between woodpeckers and trees is just to take what they need, and woodpeckers are only called the doctors of trees and give them an emotion.

Woodpeckers sometimes only peck a small hole in the trunk of a tree in order to fill their stomachs, but if they encounter a very hungry woodpecker, they will peck deeply into the trees in order to fill their stomachs as soon as possible, looking for insects hiding in the trunks. The act of pecking a tree deeply will cause the tree to be pecked and devastated, and the pecking hole too large may cause the tree to get sick or die. Sometimes, in order to catch pests, they will also peck at healthy trees, and the sap of the trees will flow out to attract pests, so they can wait for the rabbits.

Woodpeckers are beneficial birds, but they are not the doctors of trees, as people say.

Because woodpeckers are the doctors of large trees and the natural enemies of pests. It is not a beneficial bird because woodpeckers can harm trees.

Because woodpeckers can eat some of the insects in the tree, the textbook says that woodpeckers are beneficial birds. Actually, no, woodpeckers have been destroying trees, and they don't belong to beneficial birds.

Because woodpeckers eat some of the bugs in the wood, and these bugs can harm the trees. No, it will still destroy trees when it eats some bugs, which can also cause some trees to die.

The woodpecker is a beneficial bird.

The woodpecker is a common bird that is widely distributed worldwide and lives in many different habitats. Woodpeckers are insectivores that feed primarily on insects, earthworms, and other small animals. These critters can cause damage to plants, so the presence of woodpeckers is beneficial to plants.

In addition, woodpeckers also help control the pest population. For example, if the number of woodpeckers decreases in one place, then the number of pests in that place increases, which can cause more damage to the plant. Therefore, a woodpecker is a good animal for nature, not a pest bird.

Woodpeckers can also contribute to humans. Woodpeckers can help control pests, which can be of great benefit to agriculture and horticulture. In addition, woodpeckers are also a favorite ornamental bird for many people, and people can learn about their habits and behaviors while watching woodpeckers.

Therefore, the woodpecker is an animal that is beneficial to humans.

Woodpeckers peck wood does not harm trees

The damage caused to trees by woodpeckers pecking at wood is usually limited. Woodpeckers usually peck holes in the bark of trees in search of insects and other food, but these do not cause serious damage to trees. Woodpeckers tend to have small pecking holes, and trees are usually able to repair themselves for these slag pecks.

However, woodpeckers also have the potential to cause some damage. If a woodpecker pecks too many holes in the same tree, it can cause more damage to the tree. In addition, woodpeckers may also dig up some shoots from the bark, which may affect the growth of the tree.

The woodpecker is known as the forest doctor, and when it pecks at insects, although it pecks out a hole in the tree, the tree is deprived of insect socks, and the wound will heal quickly. The woodpecker is able to prey on ninety percent of the gidding insects in the woods, ensuring that most trees can continue to survive. Therefore, according to its predatory habits, it should be a very beneficial bird, because it can help trees to clear a lot of insects that are harmful to tree growth.

On the surface, the woodpecker is far more beneficial to the growth of the forest than it is to the tree, so it is worthy of its name to be called a "beneficial bird" and a "doctor of the forest".

Woodpeckers, sometimes in order to prey on insects, will deliberately peck out of the hole in the tree to let the sap flow out to attract insects. Woodpeckers love to peck at empty tree trunks and build nests inside. Some woodpeckers have a habit of sucking the brains of young birds.

In fact, there is sometimes no fixed boundary between beneficial and pest birds, and insectivorous birds can damage crops when they are hungry. The so-called harmful birds are only relative. The definition of beneficial hazards of species varies greatly from one time to another and from one environment to another.
