Case study: Great Horned Owl with enucleated eye

Case study: Great Horned Owl with enucleated eye

On November 19th, 2020 a great horned owl with an injured eye, that had been rescued by a member of the public in Duchess, Alberta was transported to Calgary Wildlife by one of our volunteers.

Upon arrival to Calgary Wildlife, our team of wildlife rehabilitators performed an initial intake exam to assess the owl’s condition. Carefully examining the owl for injuries and symptoms of illness, staff ensured they were minimizing any sources of stress during the examination, preventing the owl from going into shock. The owl was very alert and was in good body condition, indicating that she had been able to feed recently. She was exhibiting symptoms of mild dehydration, signs of pain, and presented with an enucleated right eye, which means that the eye had been removed. The wound and tissue surrounding the eye were already in the beginning stages of infection.

The owl was assessed by one of our veterinarians, who recommended surgery to remove any of the eye tissue that was still remaining, and to close the wound to promote healing and prevent further infection.

On November 27th, staff prepared the owl for surgery. The surgery was a success and the owl recovered in our facility, feeding and gaining strength while under monitoring from our staff.

Following recovery the owl was moved outside to prepare for release.

On January 5th, 2021, after 48 days in care, the great horned owl was returned to the wild in Duchess, Alberta, where she immediately flew off.

Watch the release.

Wildlife rehabilitator, Breanne Marois, put together a full case study of the owl, the procedure, and successful release. You can read the full case study here.
