Vultures are large, ugly birds. They are scavengers, so instead of chasing down their prey, they hone in on an animal that has already passed. They then wait until the predators has left and then eat the rest of the meat. Vultures live on five of the world's landmasses, where they stalk the forests, mountains, deserts and plains in search of food. The birds are divided into two groups of species: Old World vultures and New World Vultures.
