Polynesian Imperial-pigeon (Ducula aurorae), 43 cm. Pale grey-white head and underparts; dark metallic green upperparts. Endemic to the Society Islands (Tahiti, Maupiti) of French Polynesia. Inhabits montane and lowland forest. Endangered; heavy hunting and introduced predators have caused steep decline.
