I was out side yesterday and a tiny little Sparrow came hopping into my garage. He’s smaller than an egg. I looked for his nest and couldn’t find it. I ask my girlfriend and she said there was nothing I could do. I left him outside; hiding under a flower pot. This morning I got up and he had made it through the night. I mixed up some sugar water and have been feeding it to him through the day. He’s alive. He can’t fly. His parents can’t lift him back to the nest. And I don’t think he can live on sugar water alone. Any ideas on what to feed a tiny little baby bird?
