I was contacted by the folks who had this bird in their garden, as I had written a small book about the Bahama Woodstar. I live in Nassau, Bahamas, and am a professional photographer and have taken a lot of photos of this species, which is basically our only hummingbird. I would love to know how he got all the way to PA! I doubt it would have been Sandy that blew it up there as I would wonder how it survived the wicked winter that followed. Perhaps you would enjoy some of the photos I have on my web site at

One thing though, I have a picture of a Bahamas Woodstar on my web site with its tail feathers fanned out, and the markings are different from the one seen in Pennsylvania.
