I had one of those that showed up and stayed for about a week. He plunked himself on a branch right next to the feeder and guarded it day and night. No other hummingbird could get close to it. He had the most beautiful iridescent copper colored breast....but MEAN he was!!! I was happy when he decided to move on.
I had the SAME thing happen! The only ruby-throated one I ever saw here and he was mean and selfish and loud! LOL!
I wonder if he makes the rounds among us! LOL!
My other hummers were mighty glad when he moved on! :D
