The conclusion that pigeons and other birds can find their way home from unfamiliar areas by means of olfactory signals is well based on a variety of experiments and supporting investigations of the chemical atmosphere. Here I argue that alternative concepts proposing other sources of geopositional information are disproved by experimental findings or, at least, are not experimentally supported and hardly realistic.
鸽子和其他鸟类能够通过嗅觉信号从陌生区域找到回家的路，这一结论是基于各种实验以及对化学环境的相关支持性研究得出的。在此我认为，那些提出其他地理定位信息来源的替代概念，已被实验结果所否定，或者至少没有得到实验支持，而且几乎不现实。
