Coraciiformes
There are over 250 species in this order, which includes kingfishers, bee-eaters, hornbills, and others . Most species are found in the Old World (Afria, Europe, and Asia) except for kingfishers which can be found worldwide. These birds differ greatly in size (small bee-eaters to very large hornbills) and plumage, but share an unusual characteristic: three of their toes are joined in the same skin at the base of their foot. In fact, two of the three toes are joined almost all the way. The fourth toe points backwards, as it does in many other birds.
