But it is not very easy because the forest is covered with snow and the trees are bare

During the winter people have nice warm houses to live in, but animals have to stay outside

旁白 neutral

During the winter, you don't see many birds in the forest because most of them have migrated

冬天，你在森林里看不到多少鸟，因为它们大多都迁徙了。

In the fall, when the weather gets cool, the birds gather together and fly south to warmer places

秋天天气转凉时，鸟儿们聚在一起，向南飞到更温暖的地方。

When people travel, they use maps, but birds travel without using any maps

人们旅行时用地图，但鸟儿旅行时不用任何地图。

旁白 neutral

It is amazing that they never get lost; they know exactly where to go

旁白 neutral

Some birds use the sun, the moon, and the stars to guide them

In order to get ready for winter, we grow new, thicker fur in the fall

Squirrels, mice, and beavers get ready for winter by gathering extra food and storing it in a safe place to eat later

Sleeping during the winter is called hibernation

冬天睡觉叫做冬眠。

By hibernating, these animals save energy and are able to live on very little food

If lots of snow falls, it can actually help them stay warm, like a thick blanket

旁白 neutral

Some mice sleep in dens together with many others so that they all help each other to stay warm

有些老鼠会和其他许多老鼠一起睡在窝里，这样它们就能互相帮助来保持温暖。

旁白 neutral

Chipmunks, squirrels, and some other animals are called true hibernators

花栗鼠、松鼠和其他一些动物被称为真正的冬眠动物。

旁白 neutral

When true hibernators sleep, the temperature of their body decreases and their heart slows down, so they need less food

当真正的冬眠动物睡觉时，它们的体温会下降，心跳会减慢，所以它们需要的食物更少。

旁白 neutral

In fact, when you see true hibernating animals, they look like they are dead

事实上，当你看到正在冬眠的真正冬眠动物时，它们看起来就像死了一样。

If you touch them, they feel very cold

如果你触摸它们，会感觉很凉。

Other animals, like bears, sleep most of the winter as well

其他动物，比如熊，冬天大部分时间也在睡觉。

旁白 neutral

They are not true hibernators, however, because their body temperature cannot decrease

旁白 neutral

In order to stay warm while they hibernate, bears need to eat huge amounts of food in the fall

为了在冬眠时保持温暖，熊在秋天需要吃大量的食物。

The extra fat stores energy to keep them warm while they sleep

多余的脂肪储存能量，在它们睡觉时保持温暖。

By the time spring comes, the bears have lost most of their fat

春天到来时，熊已经消耗了大部分脂肪。

旁白 neutral

When they get hungry, they wake up for a little while and eat some of their food

当它们饿了，会醒来一会儿，吃点食物。

Many hibernating animals have a place in their little homes where they can go to the toilet

许多冬眠动物在它们的小家里有上厕所的地方。

Also if the animals get too cold, they might die
