Visited today - forgot how compact this zoo is, as I covered all but some Hoofed Animals and the Farm in a little over three hours! (And technically the seals, but probably could have seen them if not for the construction)
Walter Family Arctic Tundra looks incredibly well made and is following LPZ's trend of seeming to minimize moats and grottos for large glass structures, - but it was a bit disappointing the Polar bears did not seem interested in coming out, only one muddy bear briefly peeking out from an indoor area. I can't complain about the exhibit itself, which looks much roomier for the animals than the previous habitat.
The new penguin habitat is pretty attractive for what it is, and while I'll always have a hair of nostalgia for the out-of-date Penguin-Seabird House, it's very well-made and the penguins seem almost at the perfect eye level for visitors. I do slightly wish there was a bit more viewing area on the rock/land section, as the penguins were not so interested in the water today, though a few did make a dive.
As a side note, a few of the Chimpanzees ran outside, picked up some snow, and then immediately ran back indoors, and one of them was eating and playing with the snow. That was an interesting behavior to witness.
The Siberian tiger was also extremely active, pacing around, rolling on their back, and roaring.
Managed to glimpse a few species that have proven elusive to me in the past, such as the Red Wolf, the Sloth and the Cougar.
