Daily and annual activity patterns of the common snapping turtle were investigated from June 1975 to October 1976 in Algonquin Park, Ontario, Canada using radio-telemetry and mark-recapture techniques. Turtles emerged from winter dormancy in early May when water temperature was about 7.5 C and were captured in baited traps when water temperature reached 16.0 C. Nesting activity peaked about mid-June in both years. Turtles maintained summer activity levels until late August and entered winter dormancy by mid-October. Animals were active in the morning and early evening, basked in the afternoon, but were rarely active at night. No specific water temperature was selected for activity. Home range averaged 3.44 ha for both sexes combined, and most animals remained in the same home range in consecutive years.
