Okay, Squeaks. This is the last one. Go ahead.
好的, 吱吱。这是最后一个动物。继续吧。
Okay, your animal is a mammal and it's not very big.
好吧，你的动物是哺乳动物，体型不是很大。
Well, that doesn't really narrow it down much.
这并没有缩小多少范围。
Oh, it changes how it looks depending on the season.
哦，这种动物会根据季节改变外观。
In the winter, it has a thick white coat and in the summer it has a shorter brown coat.
在冬天，它有一件厚厚的白色外套，在夏天，它有一件较短的棕色外套。
Interesting, is it an Arctic hare?
有意思，这是北极兔吗?
Oh, darn, but I'm close.
哦，不是，但快接近了。
And your animal is a carnivore, meaning it eats meat.
你的动物是食肉动物，也就是说它吃肉。
I think I know. Is it an Arctic fox?
我想我知道。它是北极狐吗?
Hey, Arctic foxes and Arctic hares change their coats depending on what season it is to help them blend in with their environment and help them keep warm.
嘿，北极狐和北极兔会根据季节改变它们的外套，以帮助它们融入环境，并帮助它们保暖。
And there are other animals with special winter coats, too.
还有其他动物也有特殊的冬季外套。
Let's find out more.
让我们了解更多吧。
One of the best parts of winter is curling up with a blanket and a cup of hot cocoa, watching the snowfall outside while you stay nice and warm.
冬天最美好的一件事就是裹着毯子，喝着热可可，蜷缩在家里，一边看外面的雪，一边又暖和又舒服。
But what do animals do when it gets cold?
但是当天气变冷时，动物们会做什么呢?
They don't have blankets hot cocoa or heated houses like we do.
它们不像我们一样有毯子、热可可或有暖气的房子。
Well, different animals have different ways of dealing with the winter weather.
不同的动物有不同的方法来应对冬天的天气。
Some animals migrate or move to a warmer place for the winter and some of them hibernate or hang out in their cozy dens underground.
一些动物迁移或搬到一个更温暖的地方过冬，一些动物冬眠或在它们舒适的地下洞穴里闲逛。
They don't come out until it's warm again.
直到天气变暖它们才会出来。
But other animals don't migrate or hibernate and they manage to live in places with really cold winters.
但其他动物不迁徙也不冬眠，它们设法生活在冬天非常寒冷的地方。
But how do they do it?
但是它们是怎么做到的呢?
Well, they've come up with a pretty cool way to fit in with their snowy environment.
嗯，它们想出了一个很酷的方法来适应它们的雪环境。
I'll give you a hint.
我给你个提示。
It involves a winter coat not a jacket with buttons or a zipper like you or I might wear.
涉及到一件冬季大衣，而不是像你我可能会穿的那种有纽扣或拉链的夹克。
Instead, they have fur and feathers that cover their bodies when it gets cold.
相反，当天气变冷时，它们有皮毛和羽毛覆盖在身体上。
When the days get shorter, these animals shed their brown or gray colors and grow white fur or feathers to help them make it through the winter.
当白天变短时，这些动物就会褪去它们棕色或灰色的毛发，长出白色的皮毛或羽毛来帮助它们度过冬天。
Let's meet some of these color changing animals and find out how their special coverings help them survive the chilly season.
让我们来看看这些变色的动物，看看它们特殊的皮毛是如何帮助它们度过寒冷的季节的。
First up is the Arctic fox. The Arctic fox gets its name from where it lives in the Arctic.
首先是北极狐。北极狐因其生活在北极而得名。
The Arctic is located at the most northern part of the world.
北极位于世界的最北部。
Around the North Pole, Arctic foxes live on the land and sea ice where they hunt birds and other small animals.
在北极周围，北极狐生活在陆地和海冰上，它们在那里捕食鸟类和其他小动物。
But they don't always look the same from season to season.
但它们在不同季节看起来并不总是一样的。
When the days get shorter and colder, their coats get thicker and wider.
当白天变短、变冷时，它们的外套就会变厚变宽。
This is what an Arctic fox looks like in the spring and this is what it looks like in the winter with its winter coat.
这是一只北极狐在春天的样子，这是它在冬天披着冬衣的样子。
The most important thing about the fox's winter coat is that it keeps the animal warm with its extra thick fur coat and bushy tail to wrap around it body.
狐狸冬天的皮毛最重要的一点是，它用特别厚的皮毛和浓密的尾巴包裹住身体来保暖。
The Arctic fox is better at holding on to its body heat than nearly any other Arctic animal.
北极狐比几乎任何其他北极动物都更善于保持体温。
But the fur does more than just give them warmth.
但皮毛不仅仅是给它们保暖。
Their white coat also camouflages them or helps them blend in with their surroundings.
它们的白色外套也能使它们伪装或帮助它们融入周围的环境。
Blending in with the snow lets the foxes sneak up on their prey like Arctic hares and small birds.
狐狸和雪混在一起，可以偷偷接近它们的猎物，比如北极野兔和小鸟。
And it also helps them hide from bigger animals that might want to sneak up on them.
这也帮助它们躲避可能想要偷偷接近它们的大型动物。
But when the seasons change, so do their coats.
但当季节改变时，它们的外套也会改变。
In the summer, Arctic foxes shed their white coats and grow new ones that are brown or gray to blend in with their surroundings after the snow is gone.
在夏天，北极狐脱掉它们的白色外套，长出棕色或灰色的新外套，以便在雪消失后与周围的环境融为一体。
Now things can get tricky for the Arctic fox, because one of the animals that it likes to eat--the Arctic hare--uses some of the same tricks to survive the winter.
现在对北极狐来说，事情变得棘手了，因为它喜欢吃的一种动物北极野兔使用了一些相同的技巧来度过冬天。
Arctic hares also live, you guessed it, in the Arctic, mostly in forests.
你猜对了，北极兔也生活在北极，主要生活在森林里。
And like the foxes, they have thick white coats of fur to keep them warm, plus pads of thick hair on the bottoms of their feet.
和狐狸一样，它们也有厚厚的白色皮毛来保暖，脚底还有厚厚的毛发垫。
Now, some Arctic hares live further south where there's less snow.
现在，一些北极兔生活在更南边的地方，那里的雪更少。
So they actually grow darker coats that help them blend in those environments where there are more rocks and plants than there is snow.
它们实际上长出了深色的皮毛，帮助它们融入比多雪地有更多岩石和植物的环境。
No matter where they live though, Arctic hares like to keep their fur clean, so they groom themselves like cats do by licking their fur.
无论生活在哪里，北极兔都喜欢保持皮毛干净，所以它们会像猫一样舔舐皮毛来梳理自己。
The cleaner their fur is, the warmer it keeps them.
它们的皮毛越干净，它们就越暖和。
Our last animal with a winter coat doesn't have fur at all.
我们最后一个穿冬衣的动物根本没有毛。
It's a bird called a ptarmigan.
这是一种叫雷鸟的鸟。
The ptarmigan lives in the Arctic, too and can often be found hiding in bushes or behind rocks to avoid predators.
雷鸟也生活在北极，经常躲在灌木丛或岩石后面躲避捕食者。
They have feathers that change from brown in the summer to white in the winter to help camouflage them from bigger animals.
它们的羽毛从夏天的棕色变成冬天的白色，以帮助它们躲避更大的动物。
They're soft fluffy feathers are pressed close to their skin, trapping in their body heat and keeping the birds toasty warm in the snow.
它们柔软蓬松的羽毛紧贴在皮肤上，困住了身体的热量，使它们在雪中保持温暖。
They also have extra feathers on their legs and feet to help keep them warm.
它们的腿和脚上也有额外的羽毛来帮助保暖。
And ptarmigans have other ways of staying warm in the winter, too.
而雷鸟在冬天也有其他保暖的方法。
Sometimes, they'll fly straight into a pocket of powdery snow.
有时，它们会直接飞进一块粉状干雪里。
This makes a little burrow or tunnel in the snow that they can snuggle up in, kind of like the fort.
在雪地里挖了一个小洞或隧道，它们可以依偎在里面，有点像堡垒。
Whether it's an extra thick coat to help keep them warm or white fern feathers to keep them out of sight.
无论是一件额外的厚外套来帮助它们保暖，还是白色的蕨类羽毛来让它们远离人们的视线。
When it comes to living in winter, these Arctic animals have it covered.
说到冬天的生活，这些北极动物用其裹身。
Alright, Squeaks that is all of our clues.
好了，吱吱，这就是我们所有的线索。
Let's find out from the fort's computer who won. And wouldn't you know it? It's another tie.
让我们从堡垒的电脑中看看谁赢了。难道你不知道吗? 这是又一次平局。
We both know a lot about animals, huh.
我们都很了解动物。
How about as a reward we go and make some hot chocolate?
作为奖励，我们去做些热巧克力怎么样?
Then we can get nice and cozy on the couch and we can finish that book that we've been reading.
然后我们可以舒服地躺在沙发上看完我们一直在看的那本书。
The next time it's really snowy where you live, you can play guess that animal, too.
下次你住的地方真的下雪的时候，你也可以玩猜动物的游戏。
Just pick some animals make up some clues and you're ready to play.
挑选一些动物，编一些线索，你就可以玩了。
