Surprisingly, Hawaiian duck is a close allied of with another famous species duck (which I already mentioned previously) called mallard associated with taxonomic. As one of the member of duck from genus Anas, just like mallard, koloa has the ability of produce viable offspring and interbreed.

To these days, authorities has included koloa within mallard complex’ distinct species. Reviled that this species was the offspring of mallard and Laysan duck.

Associated with the body size, the males are generally bigger than the female ones. Speculum feathers in both males and females was colored in blue to green with white boarded on the two sides; although they had similar appearances like the mallard, apparently both species have different color of tail.

The mallard was known having beautiful black-and-white tail, but koloa’ tail was fully painted with black. The bill color in male koloa is olive green and in female it colors with dull orange; the legs and feet on both side was painted in to yellow-orange to fully orange.

The female measurement is about 40 to 43 cm or about 15.5 to 17 inches in length, and the weight reach about 460 grams or about 16 ounces.
