Homing movements ranging from about 150 to 700 yards have been recorded for Tamias by Seton (life histories of northern animals, vol. 1: 341, 1909), Allen (Bull. N. Y. State Mus., 314: 87, 1938), Burt (Misc. Publ. Mus. Zool. Univ. Mich., 45: 45, 1940), and Hamilton (American mammals, p. 283, 1939). While engaged in other studies during the summer of 1952, I had the opportunity of making additional observations on the homing behavior of the eastern chipmunk, Tamias striatus lysteri (Richardson), on the campus of Cornell University at Ithaca, Tompkins County, New York.
