SALT LAKE CITY, Utah — Utah’s Hogle Zoo community is mourning the loss of Riley, the beloved 18-year-old and senior member of its reticulated giraffes. Known for his towering personality, Riley was the most gregarious member of the herd.

In recent months, staff has observed some age-related challenges with his mobility. Riley was kept under close observation and under veterinary treatment for arthritis. Although he had been managing well, when zoo staff entered the giraffe barn Thursday morning, they found him unable to stand on his own. Riley was approximately 17 feet tall and weighed 2000 pounds which presented a unique challenge to get him on his feet.

Since giraffes are generally less intolerant of colder temperatures, they spend time indoors in a barn-like facility during colder winter days but have access to a heated outdoor yard as an option.

Alongside zoo staff and emergency personnel, the Salt Lake City Fire Department and Wagstaff Crane Service were on scene to assist with an all-day tireless attempt to hoist the animal to get him to his feet. Despite everyone’s heroic efforts and ingenuity, he was unable to stand on his own. As his condition worsened, Riley naturally passed later in the day.

Dr. Erika Crook, Director of Animal Health, said in a statement, “Hogle Zoo staff, and our partners who showed up immediately to assist with this giraffe emergency, did everything possible to help Riley but his condition was too advanced. We had wonderful support from other AZA colleagues who have experienced similar scenarios.”

Riley’s legacy and longevity are a testament to his dedicated team of animal care members, ensuring his well-being was a top commitment. According to the AZA Giraffe SSP, the average lifespan for a male reticulated giraffe is 14.7 years.

Associate Director of Animal Care, Bob Cisneros, said in a statement, “Riley was truly a giant; without a doubt, the first animal to stand out amongst others as guests first enter the zoo. He touched the hearts of many as a tall and dignified ambassador especially during our giraffe feeds.”

The Zoo administration gave thanks to the community for its understanding during this difficult time and for loving Riley as much as they did.
