The Brookfield Zoo has a great penguin habitat, and they are busy breeding more penguins.
One of our main reasons for the trip to Chicago was to take part in the Poolside with Penguins program. Joy got to take part in the prep work and feeding of the Humboldt penguins. She even got to pet one! She describes the feathers as sort of plasticy. There was a distinct odor to the birds as well.
My job in the Poolside with Penguins program was to try to get better pictures than the pro. I succeeded.
The dolphin and seal habitats are very cool. The view into the dolphin tank is cast in blue: the still dolphin is nearly invisible.
