Behavior
Pileated Woodpeckers forage in large, dead wood—standing dead trees, stumps, or logs lying on the forest floor. They make impressive rectangular excavations that can be a foot or more long and go deep inside the wood. These holes pursue the tunnels of carpenter ants, the woodpecker’s primary food. The sound is often audible as a heavy thunk, and large chips of wood collect on the ground below. Pileated Woodpeckers are monogamous and hold large territories; it’s rare to see more than two birds together at a time.
