Tennyson et al., 2003,
South Okarito Forest, West Coast, South Island, New Zealand.
Until recently undescribed, and thus treated as conspecific with A. australis and A. mantelli; various genetic studies show the three to be well separated#R#R#R, with present species in fact closer to geographically more distant A. mantelli than to A. australis, a conclusion backed up by evidence of feather lice#R. According to describers#R, differs from A. australis in having dorsal feathers largely brown, streaked lengthwise (2); barred outer wing (although this is presumably vestigial and normally invisible on the living bird) (2); greyer head and neck, commonly with some white markings (2); usually pinker bill and legs, with whiter claws (ns ); on average shorter bill (1); presence of unique species of feather louse (= ecological difference) (1). In the past, range of present species therefore likely to have extended farther N, perhaps onto North I. Monotypic.
