Normally placed in Anas. Closest to M. americana and M. sibilatrix. Morphological characters support a sister relationship between present species and M. americana, with M. sibilatrix basal to the two, whereas mtDNA suggests that divergence of present species took place before that of M. americana and M. sibilatrix#R. In addition, morphology indicates a sister relationship between the three wigeon species and M. falcata, with M. strepera basal to these four species, but mtDNA supports a sister relationship between M. strepera and M. falcata to the exclusion of the wigeons#R. Present species hybridizes with M. americana and infrequently with other duck species#R. Monotypic.
From Iceland and N Britain E across N Europe and N Asia to Pacific coast. In winter moves to C & S Europe, S Asia and N & C Africa, and reaches North America.
