In my experience, the "U" shaped vertical loops are indeed aggression. They
are performed by males on males, females on females, young on old birds, etc.
We notice them more when the the adult males are involved because of the
high level of wing noise produced the the thin pointed wings of the adult
males. In some instances the male can quickly shift from the dive display to
the close-in, in-your face "shuttle" that is strictly romance. We know very
little about the part played by vocalizations during the shuttle display.
Actually, we know very little about the lives of hummingbirds, PERIOD.
Ignorance is a good motivator!
