This research investigated the possibility of releasing owls with monocular vision or if they should remain in captivity. The research was a descriptive statistical cohort study where they compared owls with vision impairments to those with normal binocular vision. Four methods were carried out to collect data: surveys from rehabilitation centers and veterinarians, data from rehabilitation centers on the number of impaired owls, the flying behavior of barn owls, and the flying behavior of tawny owls. The surveys were to asses’ opinions on the release of owls with monocular vision with 15 rehabilitation centers and 15 veterinarians that replied. The Raptor Foundation sent clinical records to investigate how many owls brought in had vision problems. Flight tests were performed on 4 owls, two with visual impairments and two with vision in normal parameters. They found that there is no significant difference between the experimental and control group, determining owls with visual impairment have unaffected flight and landing abilities. The Tawney owl study was unsuccessful and not used for final conclusions. Overall, it was determined owls with monocular vision should be considered for release to see if they would be able to sustain themselves in the wild.
