| Summary: | Twelve female moose (Alces alces) were radio-collared and tracked from aircraft and from ground during the 1982 northward spring migration in central Sweden. Migration onset, speed and routes of migration, and daily activity pattern before during and following migration were studied. Onset of migration coincided with decreased snow cover and depth. All females began to migrate from April 14 to May 2. Distances moved varied from 14 - 60 km. The longer a distance to migrate the faster the females moved northwards. All females returned to summer home range used before. Females were more active in terms of movement during migration (35% of total time) than on winter (29%) and summer ranges (33%). Females spent more time in forward locomotion during migration (18%) then when on the winter range (9%). When on winter and summer home ranges, females were most active in the early morning and early evening hours. This pattern was less obvious during migration; however peaks of travelling did occur in early morning and early evening. Average distance moved/hour was significantly faster during migration (0.45 km) than on winter range (0.25 km; P < 0.01). |
