Hi. I'm new to the list, but wanted to report an interesting sighting. This morning, I witnessed what I believe were two rufous hummingbirds mating! One bird, presumably the male, was dipping and diving in a big "U" shape chasing after another bird. It was very red, so I think it was either the rufous or the ruby throated. It did this display several times right in front of me, and the sound was very loud. The birds finally dove into some brush in front of my vegetable garden, and then one flew up and perched in a tree. It was really amazing to watch! I wish I had a camera with me.
