为什么有些动物冬眠，而另一些却要迁徙？

Animals choose hibernation or migration based on how well they can survive winter conditions.
Hibernators like bears lower their body temperature, heart rate, and breathing to save energy.
Their bodies switch to burning stored fat instead of searching for scarce food.
Migrators like geese fly thousands of miles to warmer places where food remains available.
Migration requires strong navigation skills, often using stars, Earth’s magnetic field, or landmarks.
Some species, such as certain bats, do both depending on local weather and food supply.
Hibernation works best for animals that cannot travel far or lack safe migration routes.
Scientists study these behaviors to understand climate change effects on wildlife timing.
Changes in temperature can cause mismatches between migration arrival and food bloom.
Both strategies show how evolution shapes survival in changing environments.
