Figure 1 in The radiation of Austral teals (Aves: Anseriformes) and the evolution of flightlessness

Figure 1. Distribution of Austral teals (Anas spp.) in the Southern Hemisphere, including the Madagascar teal (Anas bernieri), the chestnut teal (Anas castanea) from Australia, and the brown-teal species complex from the New Zealand region. This complex comprises the brown teal (Anas chlorotis) from mainland New Zealand and the Chatham Islands, the extinct (†) Chatham Island teal (Anas chathamica), Auckland Island teal (Anas aucklandica), Campbell Island teal (Anas nesiotis), and the extinct Macquarie Island teal (Anas sp. indet.). The distribution of the grey teal (Anas gracilis) from Australasia (Australia, New Guinea, New Caledonia, and New Zealand) is not shown owing to the overlap with the chestnut and brown teals. We also omit the distributions of species recently separated from A. gracilis, which are not considered here: Sunda teal (Anas gibberifrons), Andaman teal (Anas albogularis), and the extinct Mascarene teal (Anas theodori). Distributions are based off the Cornell Laboratory of Ornithology Birds of the World website.
