As I opened our shades early yesterday AM just as the sun was peeking thru the trees, I observed 4 Hummers hovering up & down above 1 of the *cafes* (guarded tightly by 1 Lady Speedster). I made sure (w/ binocs) they were not butterflies as there were not on their usual *air-dog-fight* chasing-speed! I was in awe observing for perhaps just a minute or so. Could they really have been dancing?
There are more than usual of them this year, despite their late arrival. I have 6 Hummingbird cafes around & refilling oftener than usual as well. Of course li'l wasps are helping consume supply!
