Our understanding of the world around us and our place in it has been shaped by the social context in which we live. Much has been gained, though much has been lost in translation.

Founded in 2004, Shadow Speak, LLC offers the opportunity to explore the natural world from a different point of view.

"As an educator and teaching consultant for many years, I direct a program for difficult "at risk" youth and children with severe behavior problems. I have had the real pleasure of watching Dr. Perdue work with children and adults in the outdoors. As a naturalist his ability as a teacher was apparent. Students who had experienced failure in traditional school settings, and who had very little appreciation for the natural environment, became avid and successful as learners. Returning to their traditional school setting, they were eager to share with others the animal husbandry and primitive skills they developed and their knowledge and appreciation of the natural world."

At a recent meeting of the Huron Valley Audubon Society, Dr. Perdue gave us a unique insight into bird/raptor behavior. It was a rare opportunity for us to have a close look at behaviors that would not be apparent by merely observing in the natural world...

Craig Perdue presented a birds of prey program for the Waterloo State Recreation Area... Program participants were enthalled as they witnessed the birds in flight responding to Craig...

It seemed effortless for Craig to keep the attention of the audience throughout the presentation.

You made a fantastic impression on many of the visitors. I heard nothing but positive reviews from everyone.... They were impressed with your knowledge of the birds...it is obvious these birds are members of your family!!
