Domestic dispute?

The sound drew me to the corner on the yard. Lots of loud chirping. I've seen male sparrows face off, "gang bangs", feeding sessions, but nothing like this. If a female isn't interested in the male she flies off totally indifferent. Not this time. I've never before seen this behavior. Mature male and mature female. Perhaps the male is "displaying". If mating was the goal this sure was a mess. The male has the black bib. This all happened very fast with the birds jumping out of the frame in fractions of seconds.

And then they flew off together. If they plan a family I'll never find them.
