On Friday, two aging Asian elephants came at the San Diego Zoo after plans to move them from Seattle to Oklahoma City were disturbed by stormy weather.

They both were in climate-controlled crates on a flatbed truck traveling from the Woodland Park Zoo in Seattle to the Oklahoma City Zoo. When prediction about the storm was done for Wyoming and Colorado, animal keepers traveling with the pair made contact with the San Diego Zoo to see whether the facility can accommodate the elephants until the storm passed.

According to Woodland Park Zoo officials, the route was changed after the truck neared Salt Lake City. Presently, the elephants are in the Conrad Prebys Elephant Care Center at the San Diego Zoo.

The Center at the San Diego Zoo focuses is caring for ailing and geriatric elephants. When Bamboo and Chai came in San Diego they were tired and showed signs of muscle stress, according to Martin Ramirez, a mammal curator from the Woodland Park Zoo. Ramirez said that they both require time to walk around, stretch their legs and adjust to their new surroundings.

It is not known when the trip will start again. Three elephant experts, two veterinarians and three other zoo staffers were traveling with the two elephants. They both were the last two elephants at the Woodland Park Zoo.

"It's been a tragedy that they've spent their whole lives in a zoo since they were babies. It’s a tragedy that they're going to die in a zoo without one single day off display, being an elephant”, said activist Alyne Fortgang.
