Golden Crowned Kinglet

A tiny male kinglet flew into the kitchen window this morning. We ran outside and found his tiny body lying on the ground underneath the window. He was still breathing, so we picked him up and placed it in a soft nest up in a tree. I felt so sad, watching his little body trembling and his tiny beak open and close as he panted. I wish he would be okay but I don't think he will be. Later, I went back to look, and he had flown away!
