A closer look at the three cougars in this diorama: first the watchful mother.
And the cubs, with something catching their attention. A close look at yesterday's panel showed an additional specimen: the Townsend's vole. It shows better in person, but that grey shape between the two is it, the object of their attention.
One more panel can be found here.
Coming out of the gallery, a large video screen shows a rotating series of photographs of mammals in the wild.
