You could probably find out quite a bit by just googling Rapid City Peregrines. I was out there for a week early this month. They really don't need much help with this kind of reintroduction project however and by now I'm thinking most of the birds have fledged. I took a tiercel prairie while I was out there so he's been keeping me pretty busy.
Doug tell me more about release in the Blcak Hills would like to help if needed . Karl
