French: Canard à sourcils German: Augenbrauenente Spanish: Anade Cejudo
Other common names: Black Duck, Australian Grey/Black Duck

Taxonomy: Anas superciliosa Gmelin, 1789, New Zealand.
Often included in A. poecilorhyncha. Form superspecies with A. poecilorhyncha and A. luzonica. Probable unstable hybrids of present species and A. platyrhynchos, found on some Micronesian islands, have been considered a different species, Mariana Duck (A. oustaleti). Hybridization with several species of genus Anas recorded in captivity, and with A. platyrhynchos, producing fertile progeny, in the wild; in New Zealand over 25% of populations may be hybrids. Validity of poorly defined subspecies has been questioned. Three subspecies recognized... View all taxonomy...
