This pileated was absorbed in finding food and didn't seem to mind the birders standing 25 feet away.
It put on a show for about 15 minutes before leaving.
I left with about 250 shots.
The Pileated Woodpecker digs characteristically rectangular holes in trees to find ants. These excavations can be so broad and deep that they can cause small trees to break in half.
