Woodpecker is a famous forest bird. In addition to killing pests under the bark, its wood cutting trace can be used as an indicator of forest sanitary cutting. They forage for pests such as longicorn beetles, giddiners, winged moths and stink bugs. Due to the large amount of food and wide range of activities of woodpeckers, if a pair of woodpeckers inhabit in the 13.3 hectare forest, they can peck more than 90% of the chitin in a winter. The mouth is as straight as a chisel; The tongue is long and retractable, with short hooks at the apex; Unlike other birds, it stands on branches, but climbs on upright trunks. Its feet are slightly short, with 4 toes, 2 toes forward and 2 toes backward; The tail is wedge-shaped or elastic, and its body is mostly wedge-shaped when pecking. In this way, the woodpecker can effectively grasp the trunk without sliding down. It can also jump on the trunk, move quickly along the trunk, jump up, jump down, or crawl in circles on both sides.
