CHICAGO (CBS)–The spring snowstorm that took the Chicago area by surprise Sunday was a treat for some of the animals at Brookfield Zoo, who spent the day playing in the snow.

Among the animals caught having fun on the wintry spring day were a couple of camels, a tiger, a bison and a robin that landed in the zoo and appeared bewildered to see the unseasonable snowfall.
