Guess what we saw this morning!
猜猜我们今天早上看到了什么！
Sure, you go ahead and tell them.
对，你继续告诉他们。
Which birds did we see?
我们看到了哪些鸟？
You're right, we saw a bunch of crows!
是的，我们看到了一堆乌鸦！
and a hawk.
和鹰。
and we even saw a tiny hummingbird zipping around!
我们甚至还看到一只小小的蜂鸟在附近跳来跳去！
I think it would be fun to fly like one of those birds, too, Squeaks.
我觉得像那些鸟类一样飞翔会很有趣，吱吱。
But with all the beautiful birds out there, I also love birds that can't fly.
但是那里有所有美丽的鸟类，我也喜欢那些无法飞翔的鸟类。
Especially ostriches—huge birds that live in Africa!
特别是鸵鸟——生活在非洲的巨型鸟类！
Ostriches can grow to be 2 meters, or 6 feet tall—that's taller than most grown-ups!
鸵鸟可以长到2米，或6英尺高——这比大多数成年人高！
I know!
我知道！
That is one big bird.
那是一只大鸟。
And I bet you can guess why they can't fly.
我打赌你可以猜到他们为什么不能飞。
It's because they're so huge!
这是因为它们太大了！
Their wings aren't strong enough to lift them into the air—they're just too heavy.
他们的翅膀不够坚固，无法将它们抬到空中——它们太重了。
Instead, ostriches are built for life on the ground, and they use their legs to get around.
相反，鸵鸟是在地上生活的，它们用腿来绕行。
It helps that ostriches have some of the most impressive bird legs out there!
它有助于鸵鸟拥有一些最令人印象深刻的鸟腿！
When they need to get somewhere quickly, they can run up to 70 kilometers an hour, or 45 miles an hour.
当他们需要快速到达某个地方时，它们可以达到每小时70公里或每小时45英里。
That's faster than cars drive down some streets!
这比汽车沿着一些街道开车要快！
Ostriches normally walk along the ground, looking for plants and seeds to eat,
鸵鸟通常沿着地面走，寻找可以吃的植物和种子，
but if a predator that wants to eat them gets too close, they can run away really fast.
但如果是捕食者想要吃它们的人越来越近，他们可以很快地逃跑。
Oh, Squeaks wants to know how many other birds don't fly.
哦，吱吱想知道有多少其他鸟不会飞。
While most birds do fly, there are fifty kinds of birds that get around by walking or swimming instead.
虽然大多数鸟类飞行，但有五十种鸟类通过步行或游泳来到处游走代替。
We talked about some of them once—penguins!
我们曾经谈过其中一些——企鹅！
Remember, Squeaks?
还记得吗，吱吱？
Instead of flying, penguins waddle around on land.
企鹅不会飞行，而是在陆地上蹒跚而行。
But what they’re really good at is swimming through the water.
但他们真正擅长的是在水中游泳。
Not being able to fly really changes things for a bird!
不能飞真的改变了鸟儿的生活！
But even though flightless birds move differently, ostriches and flying birds still have a lot in common.
但即使不会飞的鸟类移动不同，鸵鸟和飞鸟仍然有很多共同点。
Can you think of anything, Squeaks?
你能想到什么吗，吱吱？
That's right, Squeaks.
好主意，吱吱。
Ostriches still lay hard eggs, just like other birds.
与其他鸟类一样，鸵鸟仍然会产下坚硬的蛋。
Ostrich eggs are some of the biggest in the world.
鸵鸟蛋是世界上最大的蛋。
They're bigger than a softball!
它们比垒球大！
If I had one here, it would barely fit in my hand.
如果我在这里有一个，几乎填满我的手。
Instead of making a nest in a tree, ostriches lay their eggs on the ground,
鸵鸟不是在树上筑巢，而是在地上产卵。
and keep them safe by staying close and scaring away any predators that might want to eat their eggs.
为了保证它们的安全，它们必须呆在附近，吓跑任何想要吃掉它们卵的掠食者。
What other things do ostriches and other birds have in common, Squeaks?
除了鸵鸟和其他鸟类，你还注意到了什么，吱吱？
That's right, ostriches still have wings and feathers.
是的，鸵鸟仍然有翅膀和羽毛。
Instead of using their wings to fly, ostriches use them for balance while they run so they don't fall over!
鸵鸟不是用它们的翅膀飞行，而是在它们运行时使用它们来平衡不至摔倒！
Their feathers are also a bit different from other birds.
它们的羽毛也与其他鸟类有点不同。
If you look closely, the feather is a bit spread out, so it's very fluffy and light.
如果你仔细观察，羽毛有点散开，所以它非常蓬松和轻盈。
Those feathers make an ostrich's wing look kind of like a big paper fan—like this one.
那些羽毛让鸵鸟的翅膀看起来像一个大纸扇——就像这样。
And it works the same way.
它的工作方式相同。
When ostriches are too hot, they can flap their feathers.
当鸵鸟太热的时候，它们可以拍打自己的羽毛。
And this can flap away hot there.
赶走炎热。
See? We can use this fan just like an ostrich uses its fluffy feathers!
我们可以像鸵鸟一样使用它的蓬松羽毛那样使用扇子！
I could use a chance to cool down after sharing all of this awesome animal knowledge with you.
在和你们分享了这些令人敬畏的动物知识之后，我可以利用这个机会凉快一下。
Would you rather be a flying bird, like a crow or a sparrow, or a flightless bird like a penguin or an ostrich?
你愿意成为一只会飞的鸟，像乌鸦或麻雀，还是不会飞的鸟，像企鹅或鸵鸟？
Which other amazing animals would you love to learn about?
您还想了解哪些其他令人惊奇的动物？
