Eurasian Tree Sparrow

I had company today. They were terrified and so were I. They said that they accidentally had flown into our balcony and had no plans on staying here longer. But they were paralyzed and I was afraid that they had brain-damages since they thought that every window in our balcony was air - and not glass. I found them at the floor when I first saw them, I almost thought that they were dead. But I could see their bodies were shaking so I put them in my sweater to see if they could get sharp on their own. As I waited, I left to get my camera, and when I came back they actually did look healthier, so I picked them up and opened the window, waited for them to get ready,(and obviously took some pictures while they did)
