Recent inquiries re: subject prompt a question of my own on the subject. A few weeks ago, I got my binoculars out to locate a woodpecker I had heard drumming. I found a yellow-bellied sapsucker going at an old elm tree that somehow was still living. A few feet over the sapsucker, a pair of downy woodpeckers engaged in an aerial dance as if in celebration of the drumming. This went on for what seemed like several minutes. I remembered seeing this behavior on another occasion and wondered if the downys were anticipating "leftovers" from the YBSS's sap wells, protecting territory, or just dancing to the music? Can anyone explain this behavior?
