title: Space use and foraging movements in the American red squirrel (Tamiasciurus hudsonicus).
abstract: This study deals with the movements of two American red squirrels (Tamiasciurus hudsonicus) in their home ranges from late spring to early autumn in a deciduous-coniferous forest in Québec. During 70 six-hour tracking sessions, the type of behaviour exhibited at any place, and its terrestrial or arboreal occurrence, were recorded. Spatio-temporal structure of the squirrels' home ranges were analysed in relation to vegetation type and food availability. Although American red squirrels are known to be mainly adapted to coniferous forests, they also exploit deciduous areas when these areas become productive. Half of the squirrels' activity time was devoted to feeding or to searching for food, and a third was devoted to moving about. Movements were performed mainly on the ground, with a rate of about 0.5 km per activity hour, and appeared to be mainly organized around the locations of food caches and food-providing sites.
