蓝角马（conchetes taurinus）和红角马（Alcelaphus buselaphus）的日活动模式存在差异。季节性也出现在每个物种的模式中。在夏季，角马吃草的时间比普通角马少，躺着和站立的时间多，这种差异在冬季更加明显。角马也花更多的时间在阴凉处，而羚羊在使用阴凉处方面没有任何规律。这些结果讨论了与温度调节适应和可能的分歧在方法上满足能量需求的两个物种。
Differences in diurnal activity patterns exist between blue wildebeest Connochaetes taurinus and red hartebeest Alcelaphus buselaphus. Seasonality also appeared in the patterns of each species. In summer, wildebeest spend less time grazing and more time lying and standing than do hartebeest and this difference is emphasized in winter. Wildebeest also spend more time in the shade whereas hartebeest do not show any regular pattern in their use of shade. These results are discussed in relation to thermoregulatory adaptations and the possible divergence in methods of satisfying energy requirements in the two species.
