Poor little thing! I’m glad it was just stunned a little and then could take off! We’ve had so many birds hit our windows over the years. I’ve put the translucent Clings on some of the windows which do seem to help with crashes. When I put up the hummingbird feeders I was worried they’d hit the patio door windows. I found some clings specifically designed to ward them off and we’ve not had any hitting the windows for a few years. Have you tried those at all?
