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.
本研究探讨了两只美洲红松鼠（北美红松鼠）在魁北克省落叶针叶林中从晚春到初秋期间在其活动范围内的活动情况。在70次为时6小时的追踪过程中，记录了松鼠在任何地点表现出的行为类型及其在陆地或树上的活动情况。结合植被类型和食物可获得性，分析了松鼠活动范围的时空结构。尽管已知美洲红松鼠主要适应针叶林，但当落叶林区域物产丰富时，它们也会利用这些区域。松鼠一半的活动时间用于进食或寻找食物，三分之一的时间用于四处活动。活动主要在地面上进行，每活动小时的速度约为0.5公里，并且似乎主要围绕食物贮藏处和提供食物的地点展开。
