Although commonly forward to the order Coraciiformes, from this level trim confusion sets in.

The kingfishers were traditionally inured as one family, Alcedinidae with three subfamilies, but postulate the 1990s revolution in bird taxonomy, the three constituent subfamilies are now lots elevated to familial level. That get off was supported by chromosome and DNA-DNA hybrid studies, but challenged on the fount that all three groups are monophyletic with respect to the other Coraciiformes. This leads to them universe grouped as the suborder Alcedines. The tree kingfishers have been previously disposed(p) the familial name Dacelonidae but Halcyonidae has priority.
