Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. The river kingfishers family Alcedinidae is one of nine in the order Coraciiformes, which also includes the motmots, bee-eaters, todies, rollers, ground-rollers, Cuckoo Roller and two other families of kingfishers. The rollers do not appear to be particularly closely related to the others groups, and the Coraciiformes are therefore probably polyphyletic. In the past, all kingfishers were placed in the Alcedinidae, but it became clear that the three subfamilies diverge...
Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. The river kingfishers family Alcedinidae is one of nine in the order Coraciiformes, which also includes the motmots, bee-eaters, todies, rollers, ground-rollers, Cuckoo Roller and two other families of kingfishers. The rollers do not appear to be particularly closely related to the others groups, and the Coraciiformes are therefore probably polyphyletic. In the past, all kingfishers were placed in the Alcedinidae, but it became clear that the three subfamilies diverged early, and the Halcyonidae and Cerylidae are usually now treated as full families, with the Alcedinidae being ancestral to the other groups.The taxonomy of the family is uncertain at present: it includes 22 to 24 species in two to four genera. The uncertainty arises from two small African species. The African Dwarf Kingfisher is sometimes placed in the monospecific genus Myioceyx, and sometimes with the Pygmy.
