Baby Squirrel Monkeys Hitch Rides on Mothers at Vienna Zoo

Vienna, Austria – Three baby squirrel monkeys are riding piggyback through their enclosure at Vienna's Schönbrunn Zoo, clinging to their mothers' fur as they take their first steps into the world.

The youngsters were born in September and are an important addition to the European breeding program for the species, the zoo said on October 20. While they still spend most of their time on their mothers' backs, they are growing bolder by the day, increasingly leaving to grab curiously at branches.
