From the art of Charley Harper, issued in 2012.
A red-headed woodpecker really knows how to use its head. Famous inspiration for Woody Woodpecker in the Universal Studios cartoon series, this bird bangs a carefully adapted skull anatomy against a tree at 100 strokes per minute and 1000 times the force of gravity. This 'flying checkerboard' is one of the top drummers out there. Compare this avian with shock absorbers in its head to a headbanger at a rock concert, and you'll find who the real Headbanger is.
