You will definitely want to take some time to visit the amazing Pittsburgh National Aviary. More than 600 birds from all over the world are exhibited in their natural habitats at the nation’s only bird facility independent of a larger zoo. Residents include flamingos, penguins, macaws, hummingbirds, and owls. Bring your lunch — bags and coolers are welcome at the tent and atrium areas. And don’t forget to visit the gift shop before you leave! The National Aviary aims to inspire respect for nature through an appreciation of birds.
