Three images.
HE'S GETTING REALLY ANGRY NOW! After having flown up/down, up/down the two kitchen windows for considerable time, chasing his image, he is getting frustrated and worn out. He would cover the north window, then fly around the corner to the east window, then back to the north - back & forth, up & down repeatedly.
Top Image: The look on his face tells the story. He wants to pound the "sh..." out of that male in behind the glass.
He shakes his head in frustration.
He finally resorts to some verbal bashing. All in vain as the phantom Redstart never did come out to play.
The male Redstart finally picked a basement window to sit in front and admire his image for some time after I had closed the kitchen curtains.
