(Portland, OR) -- The Oregon Zoo's youngest black bear, named Takoda, has died. The bear was under anesthesia for a routine health check on Friday when it went into cardiac arrest. The zoo's staff performed CPR for more than 30 minutes, but he couldn't be revived. Takoda's name means "Friend to all" in Sioux. He was orphaned in Montana and arrived at the zoo in Portland in 2010.
