Taxonomy: Motacilla cayana Linnaeus, 1766, Cayenne, French Guiana.
This genus and Cyanerpes were previously regarded as members of a separate family, Coerebidae, but later placed in present family on basis of similarities in skull anatomy; molecular phylogenies indicate that the two genera are sisters and form a monophyletic group with Tersina. Eight subspecies recognized.
