Anas chlorotis ssp. ‘Chatham Islands’

Chatham Islands Brown Duck (Anas chlorotis ssp.)

The Chatham Islands Brown Duck is only known from subfossil remains found on the Chatham Islands, that have not yet been described, it may have been a subspecies of the New Zealand Brown Duck (Anas chlorotisGray) (see depiction below) or even a distinct species.

The taxon was apparently already wiped out by the Moriori, the first human settlers on the Chatham Islands. [1]
