Daito wren
The Daito wren is a controversial subspecies of the Eurasian wren. It is known only by the type specimen, a male collected in 1938 on Minami Daitō-jima, the main island of the Daito Archipelago east of Okinawa. Yamashina described the bird as a new subspecies after comparing it with 114 specimens from surrounding areas and under the impression that the Eurasian wren is a fairly sedentary bird, not liable to be drifted astray over long distances. Its scientific name honors Yamashina's specimen collector, Hyojiri Orii.
However, stray Eurasian wrens have more recently been found on Yonaguni and Okinawa Islands. Thus, it has been hypothesized that the Daito bird was just a straggler from the Honshū, the Yakushima/Tanegashima or the Izu Islands population. As the specimen exists, it should be possible to resolve its status by DNA analysis. Certainly, many bird populations on islands south of Japan became extinct in the late 1930s as settlement and civilian and military construction destroyed large amounts of habitat.
