兽皮

The barterer exchanged trinkets for the natives furs.

货贩子用小件饰物换取土著的兽。

In some tropical regions small boats used to be made of skins stretched over a wooden frame.

有些热带地区小船是用兽绷在一个木头框子造成的。

Do a few withered grass, feather or hide lid to be on scree next, make it an incubative nest.

然后弄一些枯草、羽毛或兽盖在小石子，做成了一个孵蛋的窝。
