In addition to the babies born at the zoo orphaned grizzly bear cubs Mike, Thor and Boo, who rescued from Alaska, made their debut in the spring.

The zoo’s newest crowd-pleaser is the Boardwalk at the Cotton Family Wetlands, a 2-acre Michigan ecosystem teeming with native fish, frogs, turtles and birds. 

The Boardwalk experience opened in July.

What's new at the zoo for 2013?

The zoo says a new animal habitat will give visitors up-close, underwater views of a pair of North American beavers.

Named for the benefactors whose support is making it all possible, the Jane and Frank Warchol Beaver Habitat is under construction and will open in late spring.

The new exhibit will be located across from the current river otter habitat.
