The various forms of comfort behavior of the red squirrel (Tamiasciurus hudsonicus) are described and compared with that of other Sciurids to understand their adaptative value for the red squirrel's arboreal way of life. The different comfort activities are: self-grooming, stretching, resting, sleeping, elimination and nose blowing. Observations were made both in nature and in two outdoor enclosures. The discussion shows that most adaptations are common to arboreal squirrels while others, found in several Sciurid species, are not in relation to the arboreal versus terrestrial way of life.
本文描述了北美红松鼠（Tamiasciurus hudsonicus）的各种舒适行为，并将其与其他松鼠科动物的行为进行比较，以了解这些行为对北美红松鼠树栖生活方式的适应价值。不同的舒适行为包括：自我梳理、伸展、休息、睡眠、排泄和擤鼻。研究人员在自然环境和两个室外围栏中进行了观察。讨论表明，大多数适应性行为是树栖松鼠所共有的，而其他一些在几种松鼠科物种中发现的行为，则与树栖和地栖的生活方式无关。
