The Redheaded Woodpecker is striking at rest and in flight, showing its colors, and one of the most aggressive members of the family and one of the most omnivorous.
One of only four woodpeckers known to store food, this redhead is the only one known to cover the stored food with wood or bark. It hides insects and seeds in cracks in wood, under bark, in fence posts, and under roof shingles. Grasshoppers are regularly stored alive, but wedged into crevices so tightly that they cannot escape.
Now doesn't that sound like the redheads you know?
In addition to attacking other birds to keep them out of its territory, the Redheaded Woodpecker is also known to remove the eggs of other species from nests and nest boxes, destroy nests, and even to enter duck-nesting boxes and puncture the duck eggs.
