Activity patterns of American Martens, Martes americana, Snowshoe Hares, Lepus americanus, and Red Squirrels, Tamiasciurus hudsonicus, in westcentralMontana

We investigated winter activity patterns of American Martens, Martes americ ana, Snowshoe Hares, Lepus americanus, and Red Squirrels, Tamiasciurus huds onicus, in westcentral Montana between November 1994 and March 1995 using d ual-sensor remote cameras. One hundred percent of Snowshoe Hare (n = 25) ob servations occurred at night while Martens (n = 85) exhibited random activi ty during diel and nocturnal hours and Red Squirrels (n = 22) were diurnal. Marten activity coincided with the nocturnal and diurnal microtines and di urnal Red Squirrels though they could take advantage of the strictly noctur nal Snowshoe Hares.
