Abstract:Bird populations were tallied in weekly observations made at sunrise during the periods from March 11 through August 26, 1953, and April 17 through August 25, 1954, on a 100-acre plot of upland farms and farmyards at Setagaya, near Tokyo, Japan. Twelve species, including one summer resident were regularly recorded. The two most abundant species were the Tree Sparrow (Passer montanus) and the Ashy Starling (Sturnus cineraceus). The total population recorded increased from fewer than two birds per acre in April to nearly four birds per acre in August. Population changes of the 12 species are discussed.
