So birds can fly, and as result they have spread themselves every corner of the world. And yet, despite this fact, very few individual species have managed to find a way to conquer the world on their own. Well, nearly none, because there are five birds, just five that have found their way onto every continent. These birds, the cosmopolitan birds make up an exclusive club. Join me in this episode to meet the five birds that have spread themselves around the world. Find out how they did, and why so few birds have managed the trick.
