Lecture: Animal Migration

In this lecture, we'll examine how migrating animals navigate over vast distances.

在這場講座中，我們將探討遷徙動物是如何在遙遠的距離間導航的。

Some birds travel more than ten thousand kilometers between their breeding and feeding grounds.

有些鳥類在繁殖地和覓食地之間要飛行一萬多公里。

Researchers have identified several mechanisms that appear to guide these journeys.

研究人員已經找出了幾種似乎在引導這些旅程的機制。

Many species use the position of the sun during the day and the stars at night.

許多物種白天利用太陽的位置，夜晚利用星星。

There is also strong evidence that certain animals can detect the Earth's magnetic field.

也有強而有力的證據顯示，某些動物能夠感知地球的磁場。

Sea turtles, for instance, seem to return to the very beaches where they hatched.

例如，海龜似乎會回到牠們當初孵化的那片海灘。

However, artificial lighting and climate change are increasingly disrupting these patterns.

然而，人工照明和氣候變遷正日益擾亂這些規律。

Understanding migration is therefore essential for designing effective conservation policies.

因此，了解遷徙對於制定有效的保育政策至關重要。
