That's interesting, Carl. I deer hunt at Bernheim Arboretum (private management hunt) and see pileateds all the time down there. When they come flying into my area, they are almost always in twos and threes, so much so that I've wondered if they mate for life. Not sure. Also, I call them The Wrecking Crew of the Forest because in that area they typically find dead limbs/bark and slam into it full speed. Wood flies everywhere, then they hook on and look for grubs and bugs.
