The Toronto Zoo has announced the death of Brytne, a much-loved 13-year-old Sumatran Tiger that was killed this morning in an altercation with a 3-year-old male tiger named Harimau Kayu.
Zookeepers attempted to separate the two animals after a fight broke out, but they were too late to save Brytne.
Veterinarians have confirmed the death was the result of a crushed larynx.
Harimau Kayu arrived in June from the San Diego Wild Animal Park on a Species Survival Plan breeding recommendation, zoo staff said in a statement.
The zoo has been working for the past six months to successfully introduce the pair into the same habitat.
Brytne had already produced two litters of cubs with another male, Rengat, the zoo said.
Staff had been working over the past six months to carefully introduce Brytne and Harimau Kayu, and get them to reside in the same habitat, it said.
The pair had been showing positive behaviours since October, such as nuzzling and chuffing, the zoo said.
“Zoo staff is devastated by the loss of this beautiful and loved animal of the Zoo community,” the statement said.
