Since we were young, we have been educated. The woodpecker is a friend of mankind and a guardian of the forest. However, this may be a series of childhood deceptions.
After so many years, according to the latest research results, the “bird setting” of the woodpecker may collapse.
Woodpeckers actually hurt the tree very much. Although they eat the worms on the trunk, when the worms are in the deep trunk, they will also bite a large hole in the healthy trunk.
And woodpeckers burrow in the trees, often not only for food, sometimes for nesting, and even for storing food.
