At the Aviary in Pittsburgh we met Preston the Penguin, and spent around an hour with him. We also toured the kitchen: highlights, a frozen rat and the live insect bins. Many of the birds are in fact vegetarian, though, and eat veggie pellets, chopped kale, or spaghetti. Then there are bald eagles and sea eagles. Rats. Eleven African penguins including Preston live in a beautiful enclosure with all the penguin amenities. We had a wonderful time.
