This one has been around awhile now. I’ve seen it come to my inbox via email numerous times. Still, it is an amazing video of the tenacious defense of a nest by a woodpecker.
The last time this came to me it was noted that the woodpecker was a “Mexican” woodpecker. I don’t know what that is. It appears to me that this is a common Pileated Woodpecker that makes it’s home all over the United States.
