CALGARY, Alberta (Reuters) - A zebra has died of unknown causes at a Canadian zoo that has come under fire for several animal fatalities in recent years, officials said on Friday.
A 13-year-old Grevy's Zebra died at the Calgary Zoo's breeding facility on Wednesday after it was found collapsed in a heated barn, the zoo said in a statement.
Veterinarians at the satellite facility, located outside the city, managed to revive the animal, named Igali, but it was unable to stand and later died, officials said.
The zebra, which is native to Eastern Africa, was born in Florida and had lived at the zoo for six years. A zebra's life span is normally about 25 years.
The zoo said it expects results from tests to determine the cause of death in early 2011. It said its staff saw no previous health problems.
A hippopotamus, four gorillas, a capybara and 41 stingrays were among creatures that died at the Calgary Zoo in recent years.
In June, the zoo officials adopted a plan to improve animal care practices after independent auditors uncovered systemic problems that they said contributed to numerous animal deaths as well as safety infractions.
