Zoo animals celebrate St. Patrick's Day

Sophia, a 33-year-old Bornean orangutan at Brookfield Zoo, is gathering all the shamrock-shaped monkey biscuits she can. Zookeepers gave her the treats in celebration of St. Patrick's Day as well as decorated the Tropic World: Asia exhibit with green-colored wood wool. <span class=meta>(Jim Schulz/Chicago Zoological Society)</span>
