Hummingbird watching while sitting on my patio is a joy to experience. They are magical and beautiful, but also feisty and territorial. I have at least two couples that constantly visit my feeders. Sometimes it's like a "Star Wars" scene, where they sky-bomb each other. They are tons of fun to watch.
Yesterday afternoon, as I sat on the patio reading and enjoying the nice evening, one of the females came up within about a foot and a half from my face and just flew in place looking at me. She did this at least five times. It was an amazing experience.
