This little bird smacked hard into the front windows and fell to the ground, he was moving his head around, but not taking off again when I had to leave. I couldn't tell if he was just shaken or mortally wounded, but his neck didn't seem broken.
I needed to be able to let the dogs and the cat out to pee, so I picked him up and put him in Bay's stall, where he could have some protection from the pets and still fly out if/when he got his wits together.
He was gone when I got home, so I'm hopeful.
