Thanks for taking care of the birds. For campers who get in a similar situation, it may be helpful to know that some zoos have animal rehab centers that take in injured or orphaned wild creatures and then release them when they're able to fend for themselves.
My wife, a retired RN, volunteered at the rehab center at the N.C. Zoo. She got to care for and often hand-feed all types of animals (but not the zoo animals, which have their own medical teams). These were animals just like the birds you found, plus snakes, owls, hawks, possums, bobcats and any other wild creature that needed help. Then they release them, if possible, in the same geographical areas where they were found.
Thanks again for being a friend to wildlife. For those who can't find a zoo with a rehab facility, there are all types of other organizations that do the same type of work, if you're willing to make the effort to find them. I imagine local veterinarians would know about the local organizations that do this.
