Call your local game & fish department or veterinarian office, they will usually have numbers of local wildlife rehabilitation workers or volunteers. If the birds appear unhealthy then it will be in their best interest to go to someone who has had experience with dealing with them, I've been able to release some birds myself that were in shock, but if any birds I find appear to be more than I can handle then I always call someone who knows what they are doing.

Please consider it! Let us know what happens.

Also, baby birds (depending on how young) will eat different food than the adults do, so keep that in mind. I've been able to feed baby sparrows hard cat food soaked in water until I could find someone who could take them in.
