I did want to add this from the net as well.

"Drumming
Drumming is the term given to a woodpecker's habit of hammering loudly and rapidly onto some resonating surface, such as a dying tree, stop sign, chimney, or house. Since woodpeckers do not have a song as do passerine birds, drumming may serve as a territorial signal similar to bird song and it may also serve to attract a mate. Both sexes are known to drum."
