The annual migrations of wildfowl and many other animals certainly cannot be regarded as a form of exploration, because such movements are actually only shifts from one habitat to another for the purpose of avoiding seasonal climatic variations.

野生禽類和許多其他動物每年的遷徙，當然不能被看做是一種探險行為，因為，這些遷徙活動實際上隻是從一個棲息地轉移到另一個棲息地，以躲避氣候的季節性變化。
