Bluebird pair.......a bit of posturing and territorial display; "this is my mate and this is our box".
There were several pair of birds investigating boxes along "Bluebird Lane". Once this pair laid claim to a box, the male in particular became quite aggressive. He perched on its top. And if another bird attempted even so much as a flyby, he went into a display of vigorous wing flapping and foot-stomping, accompanied by a steady stream of chattering vocalizations; which I surmise contained very specific instructions for the perceived intruder.
