Nice work...excellent information on hummingbird feeders...I have found a couple of dead Anna's hummingbirds in my backyard in past years in the middle of winter...they are resident in our area, but I think some winters get a bit too cold for them and they have trouble surviving the night.
@@Biodiversity-Institute thanks, and sorry to hear that. I’ve once found a hummingbird in torpor hanging upside down off my feeder; it was the strangest thing. I didn’t see it the next morning so I was left assuming it was fine.
@BackyardBiologyBoys Hanging upside-down...yes if I recall correctly the anatomy/physiology of bird feet is such that when they relax their feet the toes, or talons in raptors, will close shut. It may roost upside-down, perhaps, to better avoid predation while roosting or to sway in the wind or just because hummingbird feet are rather weak compared to other bird families...just a hypothesis I don't know...the two dead anna's hummingbirds I found were on the ground.
