The Fort Wayne Children's Zoo said Teddy the tiger was moved to the San Diego Zoo last week as part of the Association of Zoos and Aquariums' conservation breeding program for the species, which experts believe has reached a population of less than 400 in the wild, The Journal Gazette, Fort Wayne, reported Tuesday.
"Though we are always sad to see animals leave, knowing that they could breed and increase the population of this species makes it worthwhile," zoo animal curator Mark Weldon said.
The zoo's other Sumatran tiger, Kemala, moved to the Toronto Zoo in December.
The Fort Wayne facility said it is preparing to receive two other Sumatran tigers, Indah and Bugara, sometime this month. The tigers are coming from the Cameron Park Zoo in Waco, Texas.
