I have the great pleasure today to watch two hummingbirds do an aerial display that would put the Blue Angles to shame. It was two ladies doing it which surprised me. I always thought that it would be one of each sex or two males having at it. I noticed that they were going into the two Leland Cypress trees I have in my front yard. I wondered if they were 'protecting' their territory from each other. They swooped, and dove, and hovered, and pecked at each other, and then would stop, and one would sit on the frame where the feeder is located and the other in a nearby tree. Then in a few minutes they would start again. This has been going on now for two days off and on. The wife said that I should get a video of them. I told here there was no way I could keep up with their movements. Very impressive little creatures!
