And one of these Grebes came along while we were rowing.

我们划船的时候，来了一只北美鹓䴘。

The grebes are joined by the highest flying birds in the world.

除了䴙䴘，这里还有世界上飞的最高的鸟。

And so we were rowing, and one of these Western Grebes came along.

当我们在划船的时候，来了一只北美鹓䴘。

These grebes aren't very good on land so they spend most of their lives on the water.

这些䴙䴘不太适合于陆地，所以牠们大部分生活在水中。

Grebes have a unique feather-eating behavior, but there are many suspicion and dispute on the mechanism of the digestion process and the function of feathers in the digestive tract.

䴙䴘目鸟类有独特的食羽行为，但对进入消化道后羽毛的功能、消化机理等存疑及争议颇多。

These birds do all of their feeding, sleeping and nesting on the water, when a family of grebes gets hungry they dive so fast that they often startle observers who call them the "Water witches".

这些鸟的吃、睡和筑巢全在水面上，当一个䴙䴘家庭饥饿时，牠们如此之快地潜入水中，会让观察者惊骇不已，称牠们为“水巫婆”。
