Wow! Isn't that awesome?
哇! 那不是很棒吗?
Oh! Hi there!Squeaks and I were just doing a little birdwatching.It’s so much fun to try to spot different birds.
哦! 大家好! 我和吱吱正在观赏鸟儿。尝试发现不同的鸟儿是很有趣的。
Today we saw a cardinal… a goldfinch… and a blue jay!
今天我们看到了一只红雀、一只金翅雀和一只蓝松鸦!
Good observation, Squeaks! Squeaks noticed that all of the birds we saw today were different colors.
观察得很好,吱吱!吱吱注意到我们今天看到的所有鸟的颜色都不一样。
The cardinal was red, the goldfinch was yellow, and the blue jay was, well, blue!
红雀是红色的，金翅雀是黄色的，而蓝松鸦，哦，是蓝色的!
It’s one of the reasons I think birds are interesting.They’re so different from one another.
这也是我认为鸟类很有趣的原因之一。他们是如此的与众不同。
Some, like the ones we saw, are brightly colored, while others are less colorful.
有些，就像我们看到的那些，颜色鲜艳，而其他的颜色不那么鲜艳。
Some birds, like this mother mallard duck and its ducklings, have feathers that are brownish.
有些鸟，像这只母绿头鸭和它的小鸭子，有褐色的羽毛。
And that’s a good thing! Their feathers help the birds to blend into their marshy surroundings, making them harder to see.
这是一件好事! 它们的羽毛有助于鸟类融入沼泽环境，让它们不易被发现。
This helps them to hide from predators that might want to eat them.
这有助于躲避可能想吃它们的捕食者。
But birds with bright feathers are much easier to spot!And those bright colors might help birds to recognize one another, or find a mate to lay eggs with!
但是羽毛鲜艳的鸟更容易被发现! 这些鲜艳的颜色可能会帮助鸟类识别彼此，或者找个配偶一起产卵!
Good question!Squeaks wants to know, what makes some birds so colorful?
好问题! 吱吱想知道，是什么让一些鸟颜色这么鲜艳?
The answer is…it depends on the bird!
答案是…这取决于是什么鸟!
Sometimes the babies of even colorful birds start out with dull feathers… and grow into their bright colors as they get older.
有时即使是色彩鲜艳的鸟，它们的幼鸟一开始的羽毛也很单调……随着年龄的增长，它们会变成鲜艳的颜色。
And one of my favorite birds, the flamingo, has a really cool reason for its bright color!
我最喜欢的鸟之一是火烈鸟，原因很酷，它的颜色很明亮!
Now when you think of flamingos, you probably think “pink”.And some flamingos are definitely bright pink!
现在，当你想到火烈鸟时，你可能会想到“粉红色”。有些火烈鸟绝对是亮粉色的!
But others are reddish orange or white, and some are even more than one color!
但其他的火烈鸟是红橙色或白色，有些甚至不止一种颜色!
Yep, it’s true!A newly-hatched flamingo chick is whitish-grey in color… and they stay that way until they’re about one year old!
是的,这是真的! 新孵出的火烈鸟雏鸟的颜色是灰白色的，它们会一直保持这种颜色，直到一岁左右!
Then something amazing happens.They start to turn color! And the secret is in how they eat.
然后神奇的事情发生了。它们开始变色了! 秘诀就在于它们如何进食。
You’re right, Squeaks, it does kind of look like the flamingo is doing a headstand!
吱吱，你说得对，这确实有点像火烈鸟在倒立!
Flamingos aren’t showing off when they have their heads upside-down, though, they’re eating!
火烈鸟倒过来的时候并不是在炫耀，而是在吃东西!
It looks a little silly, but flamingos eat by slurping up water in their beaks.
这看起来有点傻，但火烈鸟是用嘴吸水来进食的。
They have a structure in their beak that acts like a strainer, catching pieces of food for the birds to swallow whole.
它们的嘴中有一个结构，就像一个过滤器，捕捉食物碎片供鸟类整个吞下。
You know, like the pasta strainer we have in the kitchen!
就像我们厨房里的通心粉过滤器!
They eat just about anything that they can slurp up… like tiny shrimp and insect larvae. Some of this flamingo food has what we call pigment in it.
它们几乎吃任何它们能吃的东西，比如小虾和昆虫幼虫。有些火烈鸟食物中含有我们所说的色素。
A pigment is a substance that gives things color.For example, the paint we use to make colorful pictures has different pigments in it.
颜料是一种给东西上色的物质。例如，我们用来画彩色图画的颜料就有不同的颜色。
The pigment in flamingo food is orange-colored.In fact, it’s the same pigment that gives fall leaves, pumpkins, and carrots their orange color.
火烈鸟食物中的色素是橙色的。事实上，正是这种色素让秋天的树叶、南瓜和胡萝卜变成了橙色。
As the flamingo eats, over time the pigment in the food ends up in a flamingo’s skin and feathers.
当火烈鸟进食时，随着时间的推移，食物中的色素最终会进入火烈鸟的皮肤和羽毛中。
And once it gets to the flamingo’s feathers, it usually looks more pink than orange.
一旦它到达火烈鸟的羽毛，它通常看起来更粉红而不是橙色。
And the more pigment that is in the food a flamingo eats, the brighter in color the flamingos get.
火烈鸟吃的食物中色素越多，它的颜色就越亮。
In fact, if a flamingo stops eating food that has a lot of pigment in it, their feathers will fade back to white!
事实上，如果火烈鸟停止吃含有大量色素的食物，它们的羽毛就会变回白色!
So the flamingo’s diet definitely causes its color.
所以火烈鸟的饮食肯定影响了它的颜色。
Oh. Don’t worry, Squeaks!Although the same pigment in the flamingo’s diet is in carrots and some of the foods we eat… we’re not in any real danger of turning orange!
哦。别担心,吱吱! 虽然红鹤饮食中的色素与胡萝卜和我们吃的一些食物中含有的色素相同，但我们并没有变成橙色的危险!
Flamingos eat thousands and thousands of larvae and shrimp every day.And almost all of the flamingos’ food has pigment in it.
火烈鸟每天要吃掉成千上万的幼虫和虾。几乎所有火烈鸟的食物都含有色素。
We would need to eat ten carrots every day for a long time to start to turn orange!
我们需要每天吃10根胡萝卜很长一段时间才会开始变橙色!
People eat lots of different things in their diets… not just one kind of food.
人们在饮食中会吃很多不同的东西，而不仅仅是一种食物。
And although carrots are a healthy snack, we prefer to eat a balanced diet with many different foods.
虽然胡萝卜是一种健康的零食，但我们更喜欢吃多种不同食物来均衡饮食。
Say, let’s get a healthy snack…and then do some more birdwatching!
对了，我们去吃点健康的零食，然后再观察更多的鸟类!
