Our hummers live here year-round, and I am so thankful for that. Some days are just so gloomy and it cheers me up to watch them. I had to rescue one last year, though. His little feet froze to the feeder, I was walking up to the door and he was flapping his wings like crazy, trying to fly away. So I held my finger to the bottom of the feeder under his feet and warmed it. After about 20 seconds he flew away. I noticed after that, he didn't stand at the feeder anymore, he hovered. Lol.
