PITTSBURGH — The National Aviary in Pittsburgh is showcasing two snowy owls for the first time in more than a decade.

The nation’s largest aviary received 2-year-old Tundra and 5-year-old Glacier from a falconer who had been entrusted with their care by the Pennsylvania Game Commission.

A veterinarian tasked with rehabilitating wildlife says the two owls didn’t appear to have the skills necessary to survive in the wildlife.

The owls join Fleury, who has been amazing crowds with his flying in the aviary’s shows for about five years.

Trainer Cathy Schlott says snow owls aren’t particularly wise, but they are “95 percent effective” in stalking and killing their prey.

Snow owls aren’t currently endangered or threatened, but they do face climate change-related challenges.
