Endemic to Hawaii,<\/strong> and resident on Kauai, Oahu, and the Big Island, where it inhabits streams and ponds.\u00a0 Unlike many of its relatives, it often prefers mountain streams over shallow ponds.<\/p>

Generally distributed throughout Kauai.\u00a0 On Oahu, it occurs mainly at the northern tip of the island, but sometimes appears at other wetland areas.\u00a0 On the Big Island, it is mostly limited to streams on the eastern slope of the Kohala mountains.<\/p>

Extant populations are difficult to assess because of an indeterminate amount of hybridization with Mallards.\u00a0 The hybridization itself is difficult to assess because the Hawaiian Duck is somewhat variable and some individuals naturally resemble Mallards more than others do.<\/p>

Estimates in the 2000s have been approximately 2,000 on Kauai and 100 each on Oahu and the Big Island.<\/p>

Formerly also inhabited Ni\u2019ihau, Molokai, and Maui.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
