My question is, isn't the bear grotto currently occupied? Are there currently bears in the grotto? If so, will they move them to more lush (ie:grassy) exhibit or are they older and are "expected" to die off in the short time there is before the exhibit is expected to have its first inhabitant?
The bear grotto currently houses a solitary 35-year old polar bear. The Andean died a few years back, and the other polar bear (she was ~32) was euthanized last year.
A pair of grizzly sisters occupy the adjacent Grizzly Gulch, a more recent (and decent) exhibit space. Occasionally they'll occupy the easternmost grotto when their space is being cleaned, but that's rare these days.
