One of Flat Rock Brook's most popular exhibits is our aviary where we house 6 birds of prey that are all unable to be released into the wild.  Their home is now Flat Rock Brook, where our staff provides the care that they need.  Our birds act as animal ambassadors and help us teach thousands of people each year about protecting and respecting wildlife.  Help support our special birds!  Various adoption levels allow our supporters to provide food, enrichment, and enclosure maintenance for 1 month, 3 months, 6 months or 1 year.  Each level offers different benefits, such as a photo and certificate of adoption for your raptor or even a meet and greet!  Choose your raptor today!  
Visit Flat Rock Brook Adopt-a-Raptor to adopt and learn more.

Flat Rock Brook wants to recognize and extend a big "thanks" to our adopters!
