Oldest snow monkey in North America celebrates 29th birthday

<div class="meta image-caption"><div class="origin-logo origin-image kabc"><span>KABC</span></div><span class="caption-text">Nikko turned 29 years old this week, making him the oldest snow monkey in North America. He came to a zoo in Minneapolis, Minn., in 2001.    Since then, he has been one of the dominant males. Zoo employees believe his laid-back personality has helped him survive almost twice as long as a typical male.    There are only three other living snow monkeys in the world older than Nikko.  </span></div>
