Penguins played the role of honorary groundhog last year, but a different animal will do the predicting this year.

The zoo says its Nigerian dwarf goats will make the traditional Groundhog Day prediction on Feb. 2. The goats will briefly run out into the Northwestern Mutual Family Farm Goat Yard. If they see their shadows, it means six more weeks of winter. If they don't see their shadows, it means an early spring.
