I have been birding in Sierra Vista countless times, but never knew about the hummingbird banding or even the fabulous hidden treasure that is the Casa de San Pedro. What a lovely place to stay, where you can get 10 life birds before breakfast just walking to the parking lot to get something out of your car. My sister and I went for mother's day; unfortunately we didn't get to use the pool or hot tub because we birded from sunup to sundown, but I will definitely be back. We only had time for breakfast one morning, but it was healthy and delicious. My favorite things about the room were the awesome showerhead, the Eddie Bauer bed linens, and sleeping with the window open, the sound of the fountain lulling me to sleep and the bird song waking me in the morning.
