Why does a woodpecker peck wood?
Woodpeckers look for insects that burrow into wood products. woodpecker uses its strong, pointed beak to chisel insects from the wood. Then, the long mucous-covered tongue goes into action. Using barbed or hair-like protrusions at its tip, it picks up ants and spiders. Thanks to small, delicate bones that curve around the birds’ brain case and into the eye sockets, the woodpecker can extend its tongue to great lengths to snap up its insect dinner. I hope this helps to understand why woodpeckers peck wood.
