Knock On Wood!

It is not unusual to see and hear pileated woodpeckers in our yard. Recently, we have been observing one or more knocking on our neighbors' boat barn.

I am always amazed at the strength  of such a large bird. See  how it is  hanging off the side  of the roof by using its claws and stiff tail feathers? I have said, "I'm hanging on by my fingernails!" but that wasn't  what I meant. I am pretty sure that I could not accomplish such a feat with my hands or my feet. And then there is the whole "banging my head against the wall" thing. I don't usually do that literally, as  woodpeckers do.
