Winter food habits, responses to snow cover and movements of Fisher (Martes pennanti) and Marten (Martes americana) in southeastern Manitoba

A trailing and radiotelemetry study of fisher and marten was conducted from August, 1978 to August 1980 in the boreal forest of southeastern Manitoba. Snowshoe hares composed 81% of the winter diet of fisher and 53% of the diet of marten. Marten displayed more subnivean and arboreal activity, and at...
