A little bird hit the window at our house. I went to check and the bird was still alive but not moving due to shock/fear.
I wrapped him up. When I tried to put him down a few times he’d nestle down into the towel more so I let him warm up for a …while and recover from shock.
Then we went back outside and encouraged him to hang out in an old bird nest. While in the nest he still let me pet him although he was on his own legs by then.
Eventually he hopped on the rim of the nest and flew away. All pictures are here: http://www.flickr.com/photos/oboros/sets/72157622460511205/
