Okay, I posted this on emergencies, and someone said it might be a better idea to see what you all had to say. I let my little dogs out and they alerted me to this bird in my yard. I don't know what happened to it. Could have flown into a window.. or sick?? No idea. But when I got out there, it got scared of my barking dog and it flew off a good 20 feet or more. Landed again and I ran over and grabbed it. My dog was on the chase, too-- but fortunately didn't touch it. Brought it in, and wrapped it up in a towel. It's freezing cold! It is not wheezing, or looking obviously sick. It has been freezing here and there is no open water out there. I gave it a dropper full of water with sugar in it. That perked it up a bit and instead of laying down, it started standing up. It's still standing, but closing it's eyes and acting sleepy. I know about keeping it away from my birds, washing, etc... I'm most worried about what is wrong with it. I just don't have it in my heart to push it back outside and let it die in the cold. What do I do-- what should I look for?? BTW-- Pigeons are rare around here-- haven't seen one out here in a long time. But no leg bands are on it.
Here is a picture of it laying down when I first brought it in... and the second picture is of it now standing up.
