The National Aviary is America's only independent indoor nonprofit zoo dedicated exclusively to birds. Located in West Park on Pittsburgh's historic North Side, the National Aviary's diverse collection comprises more than 600 birds representing more than 200 species from around the world, many of them threatened or endangered in the wild. The National Aviary's large walk-through exhibits create an experience unlike any other - an intimate, up-close interaction between visitors and free-flying birds, including opportunities to hand-feed and meet many species rarely found in zoos anywhere else in the world.
