I was bow hunting about 25ft up in a tree when a Pileated landed above me and started hammering. I’m a large man and it was an accordingly large tree but boy my teeth we rattling!
It is quite something. One year we were treated to a Pileated making a hole in the tree for a nest. We thought it was impressive, but the Mrs. apparently chose a different location for nesting. It would’ve been cool to watch that, but c’est la vie.
