This woodpecker is the biggest of the common woodpeckers that are in most of America.
They will at times tear apart dead stumps looking for insects or ant nests. The woodpeckers will also eat boring beetles, termites, carpenter ants; at times they will eat wild fruits, berries, and some nuts. Some say that they will eat suet. The woodpeckers will also make holes in trees or a long gash when searching for carpenter ants.
The woodpeckers will make a hole (cavity} in a dead branch or tree for their nesting site, maybe even a utility pole. The male and female will work together drilling out the hole. The woodpeckers will more likely find another dead limb or tree the next year for their nesting site.
