A bird having a hard pointed bill for pecking holes in trees, and a long tongue for drawing out insects from holes or crevices. This tongue is armed near the end with sharp barbs, pointed backward like a fish-hook. The tongue is fastened to cartilages which extend up to behind the skull and over the forehead, and in consequence of this it can be thrust out some distance beyond the beak. Apple and maple trees are sometimes pierced by the woodpecker's holes in rings one above the other, just as farmers pierce the maple. The nest is lodged in a pear-shaped hole made in a tree-trunk, much larger than the circular entrance at the top.
