I'm taking care of a baby sparrow right now so I've been doing a lot of research! Remember to keep it warm. You could use a small hand towel. Ripped up toilet paper is good too. You can feed it baby bird formula that you can find at the pet store, crush up peanuts,scrambled eggs, uncooked oatmeal, and some water so its kind of like thick mush.make sure the area you're keeping it in is quiet. If you have any more questions you could call a vet or ask the workers at pet stores. Hope this helped and good luck!
