[obol] Anna's courtship?

[MARCIA CUTLER]

While gardening this afternoon, I was serenaded by the zittering of a male ANNA'S HUMMINGBIRD.  After a bit, this was interspersed with a louder chirp sound that at first I didn't place.  I finally realized that it could be the sound the Anna's hummer makes during its courtship dive. Sure enough, I looked up and spotted the male Anna's Hummer making about 5 rather semi-circular or J-shaped dives.  He then zipped over to a tree and met with another hummingbird and they both quickly flew off. 

I thought Anna's hummingbirds nested earlier than this.  Would they still be doing courtship displays?
