The largest woodpecker in North America is the Pileated Woodpecker (Dryocopus pileatus), if you accept that all Ivory Bills have gone to that great hardwood forest in the sky. This pair were recorded near Roche Harbor on San Juan Island, Washington, in September, 1997. The drumming is on a dead Douglas Fir and was not associated with feeding.
