That's when the center will release four birds of prey, so they can resume hunting in the wild.

London, a red-tailed hawk, came to the rehabilitation center nearly one year ago with a fractured wing. He has healed from his injuries and rebuilt his muscles with daily exercise.

"We chase them around flight cages or we work with them on the line to get them strong and ready to go again, as well as live testing them to make sure they are ready to hunt," explained Vice President Katherine Kattenbach who also said the center successfully releases about one-third of its rehabilitated birds.

"They are usually getting hurt from something we've done, because of cars, because of fences we put up, because we've taken their environment," she added. "Our goal is to kind of help make up for that and get them back into the wild. It's not always possible, but we do the best we can."

The center responds to calls throughout Missouri. Birds hit by cars often survive, but those injured by barbed wire rarely do.

You can tour the Raptor Rehabilitation Center at 5 p.m. next Tuesday, when volunteers will release London and three owls back into the wild.
