This year, Ruby-Throated Hummingbirds left this area (upper state of SC) on 9th of October even though climate was not so cold enough for them (I think). And like as previous several years, I only saw female hummingbirds these last few days. I could see male hummingbirds by the end of September but in a few days of early October they were gone. So these closed-up photos of Ruby-Throated Hummingbirds are only female ones.
Maybe this Ruby-Throated Hummingbird is a young male.
