I've never seen a living bird do this. However I have seen a female sharp-shinned hawk, an immature Red-shouldered and a Barred Owl; all of which succumbed to a very cold winter , apparently without enough to eat. They were hanging upside down in trees. When they sleep they lock their toes to the branch. Was very hard to free the above mentioned dead birds.

This morning at about 6:00am, my wife and I saw something we've never seen before. At our hummingbird feeder on the deck, we saw a hummer hanging upside down with its feet attached to the feeder perch. Assuming the bird was dead (I didn't bother taking a picture), I walked out there to get a closer look and grab the bird, then it suddenly flew away. Doing a little web research, I see that this is fairly common -- the birds fall asleep and sometimes hang upside down. Wow, crazy stuff. Anyone else ever see this?
