Less than two weeks after euthanizing its female ostrich, the Woodland Park Zoo euthanized its 12-year-old, male ostrich earlier this week due to injuries apparently caused by a fall in its African Savanna exhibit.

The bird, named Ozzie, was the sole remaining ostrich at the zoo.

Despite emergency treatments and supportive care interventions by zoo veterinary staff to stabilize the bird and treat his injuries, the ostrich was in obvious pain from severe injuries, according to a Woodland Park Zoo press release.

“The bird progressively declined and euthanasia was the most humane option,” Dr. Darin Collins, director of Woodland Park Zoo’s Animal Health, said in the press release.

Preliminary necropsy findings confirmed leg and head trauma with extensive soft tissue muscle damage.

The zoo lost its female ostrich two weeks ago after it suffered a critical leg injury during a diagnostic medical procedure to treat a chronic fungal infection. A post-mortem examination confirmed a pelvic bone fracture and a life-threatening systemic infection of the reproductive tract.

“As part of our proactive animal care program, our expert staff closely monitors the animals throughout the day,” Martin Ramirez, mammal curator at the zoo, said in the press release. “The male ostrich apparently fell into a water tub, just minutes after one of our keepers checked on him. The water tub had been a fixture on the Savanna for as long as the ostrich had been at the zoo. We are saddened to lose our last ostrich, but, unfortunately, accidents such as falls occur beyond our control.”

The zoo is investigating options to replace its ostriches but does not have immediate plans, according to the press release.
