A veterinarian will check out Kali (pronounced KUL-ee) between flights, and after arrival, the cub will be quarantined at the Buffalo Zoo for about a week to ensure it is free of diseases or parasites found in the wild.

Kali is expected to be slowly introduced to the outdoor exhibit area that will become its home before and after public hours, with an expectation that he will begin sharing the space with Luna, the female cub born in Buffalo in November, at the beginning of June, according to Rachel Gottlieb, the zoo’s spokeswoman.

The cub is expected to stay in Buffalo while the St. Louis Zoo, like the Buffalo Zoo, builds a new polar bear exhibit. The U.S. Fish and Wildlife Service has indicated Kali will be relocated to the Midwestern zoo after its exhibit is completed.
