Holes in telegraph-poles

Some woodpeckers bore holes in telegraph poles. It is not clear why they do this as such poles are almost always devoid of invertebrate prey and seldom suitable as nesting-sites being exposed and often situated in busy places such as by roads. Perhaps woodpeckers simple "need" to excavate holes and in doing so in telegraph poles males advertise their presence and home-making skills to potential mates ?
