Woodpecker Tongue Anatomy

This vintage illustration shows the functional barbs on a woodpecker's tongue. The side-view of the bird's face, likely a Hairy Woodpecker, is accompanied by a close-up inset of the end of the woodpecker tongue, which has barbs. These barbs aid the bird as it eats, picking out grubs and other treats while probing into tree trunks and through bark. This interesting anatomical illustration makes a great gift idea for woodpecker fans, biology students, bird lovers and science geeks.
