51 wood mice, Apodemus sylvaticus, tagged with chemoluminescent bulbs, were visually tracked in a series of night homing experiments. The mice did not go straight towards home, but wandered around the release area and covered distances equal to twice the radial lengths recorded. In the course of their walk, they orientated preferentially towards landscapes which resembled their usual habitat, irrespective of where their actual homeward direction lay. In spite of the randomness of their paths, homing success was good, but detailed analysis of homing time showed that the homing performances of the mice depended on the direction in which they vanished in the course of the observation period. The good fit of observed orientations with those obtained by computer simulation of klinokinesis along an axial gradient, and field observation of a vegetational gradient in the study area, are both consistent with the hypothesis that homing may have resulted from wandering, locally biased by a klinokinetic effect.
在一系列夜间归巢实验中，对51只佩戴化学发光灯泡的林姬鼠（Apodemus sylvaticus）进行了视觉追踪。这些老鼠并非直接回家，而是在释放区域四处游荡，走过的距离相当于记录的径向长度的两倍。在行走过程中，它们优先朝着类似于其通常栖息地的景观方向行进，而不管它们实际的回家方向在哪里。尽管它们的路径具有随机性，但归巢成功率很高，但对归巢时间的详细分析表明，老鼠的归巢表现取决于它们在观察期内消失的方向。观察到的方向与通过沿轴向梯度的趋动模拟以及研究区域植被梯度的实地观察所获得的方向拟合良好，这两者均与归巢可能是由受趋动效应局部偏向的游荡所导致的假设一致。
