Vienna, the capital of Austria, is known for its magnificent buildings, its cultural diversity, and its excellent cuisine. But few people are aware of Vienna’s wild side. A wide variety of animals have made the metropolis their home: from hundreds of rabbits in the shadow of the Millennium Tower to bat-sized butterflies, diving kingfishers, and beavers in the New Danube. And in the niches of historic facades, kestrels nest and watch the colorful hustle and bustle.
