Betty: Glad you got your hummers back. I have too!! Mine came back about a week ago. I have one, that I named "Pete". Pete is short & fat, which is how I know it is him. He sits on my tomato cage which is near one of my HB Feeders. DH says he is guarding "his" feeder. (And that he is.)
He works hard to keep all "interlopers" away.
I am going to keep a log so I know when they leave.
