The Daito Varied Tit is an extinct subspecies of the Varied Tit. It was formerly found on Kita Daitō-jima and Minami Daitō-jima in the Daitō group east of the Okinawa Islands, but became extinct around 1940. It seems that the last specimens collected were Kuroda's types taken in 1922, and that the last confirmed sighting was in 1938. The subspecies became extinct following the habitat destruction brought about by settlement and construciton activity in the 1930s.
