Despite being in sunny California, two polar bears at the San Francisco Zoo celebrated their birthdays this month in true, really chilly style.
Pike, 30, and Ulu, 32, got a very special sub-zero treatment Nov. 15 when the zoo had 10 tons of fresh snow blown into their habitat.
The big celebration was the zoo's way of honoring the bears' old ages, because the average life span of their species is only half their ages. This makes Pike and Ulu among the oldest bears of their kind to live in an accredited zoo within the United States.
"As the worldwide symbol of climate change, the presence of polar bears both in the wild and in zoological educational programs is a vital tool in carrying the messages of conservation," the San Francisco Zoo said in a statement.
The zoo even got a little sports action involved in the celebration. San Francisco Bulls hockey players Hans Benson and Chris Frank partied with the polar bears by shooting fish pucks into the bears' enclosure. Pike and Ulu sure enjoyed the tasty birthday treat.
