几十年来,人们一直试图证明鸽子能在实验室条件下学习磁罗盘,但迄今为止所有的实验都失败了。本研究的目的是测试如果磁线索作为真实的空间线索呈现,鸽子是否可以在操作室中学习磁罗盘方向。实验分别在局地磁场和亥姆霍兹线圈产生的总强度和倾斜度相匹配但方向不同的磁场中进行。鸟类表现出成功的学习能力,其表现水平与磁场异常的学习水平相当。此外,我们将实验室中的磁学习数据与现场归巢实验的表现进行了比较。在学习实验中更成功的鸟在不熟悉但不熟悉的地方消失的方向比在不熟悉的地方消失的方向远。这可能表明,更好的学习者以不同的方式探索未知的地方。我们的发现代表了鸽子操作磁罗盘学习的第一个证据,也提供了野外和实验室行为数据之间的联系。
A proof of magnetic compass learning by pigeons under laboratory conditions has been attempted for decades, but all experiments have failed so far. The aim of the present study was to test whether pigeons can learn magnetic compass directions in an operant chamber if magnetic cues are presented as true spatial cues. Experimental sessions were carried out in the local geomagnetic field and in magnetic fields with matched total intensity and inclination, but different directions generated with Helmholtz-coils. Birds demonstrated successful learning with a performance level comparable to that in learning studies with magnetic anomalies. In addition, we compared the data from magnetic learning in the laboratory with performance from homing experiments in the field. The birds that were more successful in the learning experiment had vanishing bearings farther away from the home direction than the group mean at unfamiliar, but not at familiar sites. This might suggest that better learners explore unknown locations in a different way. Our findings represent the first evidence for operant magnetic compass learning in pigeons and also provide a link between behavioural data from the field and the laboratory.
