I found a baby bird that can't fly. How can I help it survive?

His best chances will be to stay with his parents. If you can see where the nest is, you may briefly pick him up to place him back in the nest. Most birds do not actually have a very good sense of smell, so your scent won't cause a problem - however, your presence will frighten the parents away. If you cannot return him to the nest, the best course of action depends on how old he is. If he's got feathers and can hop, he's probably a fledgeling who is learning to leave the nest and you should leave him alone. If he's just starting to get his feathers and seems bright (can lift his head and look around), make sure he's in a safe spot (you can make a little nest on the ground with a clean towel in a small box - but don't move him far from where you found him, so his parents can find him there too) and see if the parents come to feed him. If you're convinced he's on his own, or if he's too little to have any hope of surviving on the ground (even if the parents stop by to feed him), then I recommend finding your closest wildlife rehab location and calling to see if they'll take him. Hope this helps!

It looks like it may indeed be of the Warbler species. These birds typically eat insects, so small crickets or mealworms would be recommended. Ideally, you should contact a local wildlife rehabilitator for assistance. A rehabber will have the knowledge and experience to give the bird the best chance at eventual release.

The best thing to do is to find a certified wildlife rehabilitator. Don't try to feed it until you do. Feeding the wrong foods accounts for more problems than going without a short time. Local DFW may have a list on thier website or call local vet clinics that see exotics. They may be able to help. Keep in a warm, quiet place. Minimize handling. Here's basics. http://www.wingsofhoperehab.org/injured_animal.html

Thanks for reaching out about this found hawk and including photos. Most likely a young bird that fell out of a nest. A wildlife rescue group should be contacted to provide proper nutrition and management, and to be able to train to fly and socialize with other hawks. This will increase success of re-release. Good luck.

You can definitely try to feed it, you will need to buy wet canned cat food such as Recovery or A/D (from your local vet) as well as a syringe, you will need to feed it every couple hours during the day (no need to feed during the night).

The easies solution is either Recovery from Royal canin or a/d from hills, both are wet foods designed for cats and dogs but are suitable for baby birds as well, you can draw them into a syringe and feed this bird (many times a day!)

It could be the baby bird is attempting to learn how to fly which is why he flutters to the ground. In some locations it is not legal to care for a wild animal, so it is best to try and find a wildlife rehabilitation center in your area that can properly care for the sparrow and help him be prepared for release back into the wild once he is healthy enough.
