Julio the Great Horned Owl

  • Hatched: Spring of 2000
  • Arrived at Portland Audubon: Spring 2005
  • Sex: Female

Julio was found as a baby after the tree with her nest in it was cut down. She was then raised by humans and never learned how to be an owl. By the time she was brought to the Wildlife Care Center at five years of age, it was too late to reverse the imprinting that had occurred. Releasing Julio back into the wild after she had imprinted on people would have put both humans and the owl at unacceptable risk.
