I used to feed them every summer until this happened to me last year.
I confess that I couldn't figure out how to help it free itself from its fascination(?) with or the puzzle of the "garage ceiling trap" and didn't have a net or a method of capturing such a delicate creature.
My neighbor said the same thing has happened to them a few times.
I really love hummers, so to speak, but unlike in Arizona where there are several varieties, there's only one variety here.
Kinda broke my heart to kill one with my garage or to learn that the garage ceiling is lethal to them.
Or maybe it's just that they are so dumb to get so utterly trapped like that, continually flying up at the ceiling until they die, seemingly never once looking down or looking back at the still wide open door they flew in through and could just as easily fly back out through.
I kept thinking there's a deeper message in there somewhere and haven't fed the hummingbirds since.
Did you ever try to temporarily put a hummer feeder just outside the garage door?
I had the same thing happen with a sparrow. :(
