Answers:
Absolutely not!
Are you sure it is a baby?
Baby birds fledge (leave the nest) before they can fly. They need time on the ground to hop around, climb low branches, and exercise their wings until they have strengthened them enough for flight. The parent birds will continue to feed and care for the fledglings until they are self-sufficient. If this baby has most of his feathers, he is a fledgling. Put him back where you found him, so his parents can continue to care for him.
If it has few feathers, or is still bare or mostly fuzzy, it is a nestling - it should not be out of the nest yet. If you can see the nest, and the baby does not look injured, you can place the baby back in the nest. Birds do not have an acute sense of smell, so the parents will not reject the baby if you handle it. That is an old wive's tale. Wildlife biologists and bird banders handle baby birds all the time, with their bare hands, and the parents never reject the babies when they are returned to the nests.

If the baby bird looks like a nestling, but you can not find or reach the nest, or you think the baby looks like it is injured, you need to immediately contact a licensed wildlife rehabilitator. You can find one here: http://www.tc.umn.edu/~devo0028/contact.
These people have very specialized training to care for sick, injured and orphaned wild animals. They also have the state and federal licenses required to keep these animals until they are healthy enough to be released back into the wild.
You should never attempt to care for an orphaned baby bird yourself. First, it is illegal to keep the bird, even for a short time, even if you are just trying to save it, unless you have the proper permits. All native migratory birds in the US are protected under the Migratory Bird Treaty Act, and you must have the proper permits to have them, even for a short time, even for good reasons like saving them. Many other countries also have similar laws regarding their native species.
Additionally, you do not have the necessary training to care for a baby wild bird. There is so much more to rehabilitation than keeping the animal alive until you think it is ready to be released. You have to know not only what to feed the bird, but how (please do not attempt to give the bird any liquid by dropper - baby birds can aspirate and die), how much and how often. You also have to know how to assess the birds general health and condition.
A baby bird kept in captivity must be taught to recognize and find the type of food it will eat in the wild. If it is being hand-fed, it may not associate the bugs and berries and seeds in nature as being food. It must also have the opportunity to exercise its wings a lot, so it will be able to fly on or shortly after release. When I volunteered at the Avian Rehabilitation Center, we kept the rehabilitating fledglings in a large walk-in cage with lots of shelves and branches leading from one shelf to the other, and down to the ground. We would place different types of food in the cage for them, as they were being weaned from the hand-feeding formula. We offered seed, meal worms and chopped up fruit. No fledgling was released until it was eating on its own, had sufficient weight gain, had all of its flight feathers in good condition, had no sign of diarreah or nasal discharge, had clear eyes, and could fly at least a few feet in a straight line.
These are the reasons to get the bird to a licensed rehabilitator - they have the training and the resources necessary to do all this, in addition to having the permits to do it all legally.

depends how healthy it is
