``The woodpeckers have chosen (your) house because they get a good resonating sound when they drum on it,'' said Richard Johnston, curator emeritus of ornithology at the Kansas University Museum of Natural History.
``It's an excellent substitute for a hollow tree. They communicate with other woodpeckers by drumming.''
Johnston said the drumming shouldn't last long -- perhaps a few weeks at most.
Residents may put up a temporary barrier, such as siding, in the area where the birds are pecking, until they settle down and begin nesting, he said.
It is illegal to kill the birds, however.
International treaty prohibits the killing of all wild birds except sparrows, pigeons and starlings, he said.
