Once it has hatched, both parents feed the chick with special crop milk which they make with fat and protein.

一旦孵化出来，父母都给雏鸟喂食用脂肪和蛋白质制成的特殊作物奶。

They provide “crop milk” to their young instead of having to fetch them live food.

它们为幼崽提供“农作物奶” ，而不必为它们取活食。

But even among our feathered friends, flamingo crop milk is special because it's pink.

但即使在我们的鸟类朋友中，火烈鸟的嗉囊奶也很特别，因为它是粉红色的。

Take this as an example: " Did you know that flamingo birds feed their babies with a red liquid called 'crop milk'? It's true."

你知道火烈鸟用一种叫‘庄稼奶’的红色液体喂它们的幼鸟吗？这是真的。

Instead, it consists of a substance called crop milk because it's stored in the parent's crop, and flamingos are one of only three birds that can produce this stuff.

相反， 它是由一种叫做嗉囊乳的物质组成的， 因为它储存在父母的嗉囊中，而火烈鸟是仅有的三种能够产生这种物质的鸟类之一。
