It’s rare for me to see one Pileated Woodpecker, let alone two Pileateds at once. But when you do see two woodpeckers together at this time of year, you might be lucky enough to see this!
The Pileated Woodpecker pair stays together all year, defending a territory in a particular area containing suitable dead wood. They create new nest holes each year, leaving the old ones for other tree-nesting species. Sometimes their excavations are so large and so vigorous they actually topple the top of the snag right off.
