Yesterday I found an adorable, tiny wren floundering on the steps of the farm store. I presume he had flown into the glass of the door. I scooped him up so Zinnie or a cat wouldn't get him.
Nothing seemed broken, but he didn't attempt to fly away, so I was worried about a possible internal injury. I carried him around on my hand for almost half an hour.
Finally, after perching on my little finger for a while, he flitted off into the trees. I think he will be ok.
