Feeling down about the deaths of J.D. Salinger and Howard Zinn? Cheer up with the Bronx Zoo bear cubs! Here they are today "tumbling, splashing, and wrestling their way through their new home at the zoos Big Bears exhibit."

The Wildlife Conservation Society announced the debut of three young orphaned brown bears and one young grizzly bear, recently rescued in Alaska and Montana. WCS's Jim Breheny reports back that “all four bear cubs are healthy and adjusting quickly to their new surroundings... We are happy to provide a home for these beautiful animals that would not have been able to survive in the wild without their mothers.”
