Good luck!
That's a myth Donna...a bird won't reject it's own babies, and are well known to nurture other species even. Is there any way to fasten a basket into a tree high up enough for the parents to respond? Chances are good the adults are in the area, and will respond to the cries of the fledgling. If there's no possible way of doing so, I'd find a re-habber that knows the proper diet for the bird, and knows how to release it without the baby imprinting on humans too much. Here's one link I found by typing "fledgling birds". http://www.la-spca.org/education/others/wild_birds.htm
It's very difficult raising many types of songbirds, and the vast majority won't make it. Starlings, sparrows etc. are more rugged, but it's much better to get the bird to someone who knows how to care for the bird properly. Good luck!
