A bird of the Anatidae family, found in southern China, India, Southeast Asia, Sumatra, Java, southwestern Borneo, etc. In Japan, it was named after the fact that it has been recorded on Okinawa Island and the Yaeyama Islands. However, it has not been observed recently, and its habitat in the Ryukyu Islands is unknown. Total length is about 41 cm. Its whole body is dark reddish brown, with gray and dark brown horizontal stripes on its back. The beak and legs are black. Sexes are the same color. Because its legs are long, they extend further back than the tail when flying. Source: Heibonsha World Encyclopedia, 2nd Edition Information |
