The Daito Winter Wren (Troglodytes troglodytes orii) is a controversial subspecies of the Winter 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 Winter 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 winter wrens have more recently found on Yonaguni and Okinawa Islands. Thus, it has been hypothesized that the Daito bird was just a straggler from the Honshū (T. t. fumigatus), the Yakushima/Tanegashima (T. t. ogawae) or the Izu Islands (T. t. mosukei) population (Vaurie, 1955). As the specimen exists (Yamashina Institute for Ornithology collection No. 25476), 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.
