The Lucifer Hummingbird is rare to the US, only found in Western Texas and Southeast Arizona. However, it is a regular at The Ash Canyon Bed and Breakfast in the Huachuca Mountains of Southeast Arizona. He remains most of the summer. This year there were up to 20 of them hitting the hummingbird feeders each day at Mary Jo's B&B. So if that's the one you want to see, that's the best place in the US.
