According to our Birds of North America book, Mr. Woody Woodpecker (aka pileated woodpecker):
Uncommon and local; a wary bird of extensive deciduous or mixed forests. Solid black back distinguishes it from other large birds except crows or some hawks. It is conspicuously crested in all plumages. Flight is strong with irregular flaps of wings. Drumming is distinctive: loud, slow, softer at end. Call is a series, never single.
It is very cool to have such spectacular neighbors.
It is also very hard to get anything done when they come visiting. Much more entertaining than anything on television.
