How to Take care of a baby sparrow? what do i feed it?

Sparrows are seed eaters and you will need to force feed it four tiny (rice sized stones) and then give it some seeds from a wild bird seed mix. The stones are needed to grind the seeds and the parents may or may not have already given them to it. If you are not going to do this please put it up in a nearby tree and stay away so you do not scare the parents from coming to care for it. They will hear it and come feed it.
