Percentage of radio-collared cow Moose, with and without calves, associated with other yearlings and adults at Rochester during October 1975 - April 1978. Seasonal Movements and Home Ranges We analyzed four types of Moose movements at Rochester: (1) short-term movements (3-14 d) between successive relocations; (2) seasonal "migra- tions" between lowlands to the east and uplands along the Tawatinaw River to the west; (3) seasonal shifts between lowlands and immediately adjacent uplands in the eastern portion of the study area; and (4) disper- sal from the study area. Movements between successive relocations of year- lings and adults were usually < 2 km, with 87% being 5 km than did cows. This was owing to the greater distances (means vs. km) between seasonal ranges (Table 3) and longer movements during the rut. Phil- lips et al. (1973) and Best et al. (1978) noted similar seasonal differences in length of daily or short-term movements. As indicated in (2) and (3) above, our radio-collared Moose at Rochester exhibited two types of seasonal movements. The first involved five cows that made annual moves between their winter ranges along the Tawatinaw River uplands and summer ranges in the muskeg and lake region to the east. Three characteris- tics set this "migratory" cohort apart from the four "nonmigratory" cows that remained in the muskeg and lake region throughout the year: (1) individuals moving to the Tawatinaw River area were traditional in their use of wintering areas during successive win- ters, , all were found on the same winter ranges during three successive years; (2) routes of travel between seasonal ranges were approximately the same each year; and (3) four of the five cows had no overlap between winter and summer ranges, and the other had only an 8% overlap (
