Abstract: | Nomadism in Tengmalm's owl was studied on the basis of Finnish ring recoveries. Natal dispersal was more extensive than breeding dispersal and more extensive among females than among males. The latter trend was found also in breeding dispersal: females, which are larger and adapted to preying on cyclically fluctuating voles, change their breeding areas more readily than males, which are smaller and can hunt alternative prey. Finnish owls seem to be more nomadic than those breeding in Central Europe. This is in agreement with the prediction that nomadism is favoured by long intervals between years suitable for reproduction. |
