Juniper

Juniper-Great-Horned-Owl

Great Horned Owl (Bubo virginianus)

Juniper came to the Medina Raptor Center in 2008 as a first year bird after it was suspected that she was exposed to herbicide. The exposure has compromised her vision in both eyes and has affected her immune system. Because of these injuries, she has gone on to become a wonderful educational ambassador to the Medina Raptor Center.
