Boris-Barred Owl

 

 

Barred Owl (Strix varias)

Boris came to the Medina Raptor Center in December 2007 from Mayfield Village as an adult of unknown age. She suffered a right wing fracture mid-shaft from unknown causes. Due to this injury, she has restricted ability to fly, being unable to gain any considerable height or sustain any flight. She currently shares her enclosure with Aurora, and serves as an educational ambassador for all Barred Owls.
