一项为期两年的对山野兔种群颜色变化的实地研究表明，温暖的春天颜色变化的速度明显快于寒冷的春天。在单独标记的野兔中也发现了同样的结果，表明这种反应不是由于年龄或性别比例的差异。据推测，白色被毛是为了伪装，由于被毛的厚度，它被穿的时间与温度有关。换羽的时间可能取决于白昼的长短，换羽的速度受温度的影响。
A two-year field study of colour change in a population of Mountain hares showed that the rate of colour change was significantly faster in a warm spring than in a cold one. The same result was found in individually marked wild hares, indicating that the response is not due to differences in age or sex ratios. It is postulated that the white coat is for camouflage, and the duration for which it is worn is correlated with temperature because of the coat's thickness. Moulting is probably timed by daylength, and the rate of moult affected by temperature.
