I just visited the zoo for the first time since America Trail opened and I'll give my impressions:
It is great to have the zoo properly connected by paths now!
The sea lion exhibit is very nice. The underwater section is the highlight of it and it's very strong as the window is quite large width and height wise. The seating is also nice for the daily demonstrations they do. It would be nice if they had a male, though.
The grey seal exhibit is just decent. Do they just have one seal?
The eagle exhibit is also nothing special, but I like how it's a backdrop to the seal exhibit.
The wolf exhibit is actually quite nice as it is spacious, has varied terain and is well developed foliage wise (as expected since they're using the old exhibit), and I love how they have mesh, glass, and open viewing, which is an important thing to me.
The beaver exhibit is pretty large and is solid.
The otter exhibit is very large and looks to be very nice for its inhabitats. The glass viewing is solid and there are multiple good viewing spots. There are obvious cross views of people, which I know some people don't care for.
Overall, I think this is a very nice section of the zoo and it met my expectations since much of it wasn't expected to be improved much. I do wish they would add some exhibits, though. Some combination of black or brown bear, mountain lion, bobcat, moose, elk, and bison would be great. I know they don't have the room for all of those, but one of the bear species, one of the cat species, and possibly a hoofstock exhibit would be great.
