像窝里的松鼠一样舒适(Snug as a squirrel in its nest)

嘘，它在睡觉。但不要把这和冬眠混淆。树松鼠，比如苏格兰的红松鼠，冬天不会冬眠。冬眠更像是地松鼠的一种特征。但红松鼠对睡觉的地方很挑剔，大多在常绿树洞里高高地筑巢。鸟巢通常用树叶、苔藓和草等柔软的材料做衬里。这只小睡鼠在地衣和松针的帮助下，用它浓密的尾巴取暖。
原文：
Shhh, it's sleeping. But don't confuse that with hibernating. A tree squirrel, like this red squirrel in Scotland, doesn't hibernate during the winter. Hibernating is more of a ground squirrel trait. But the red squirrel is particular about where it sleeps, mostly building its nest, or drey, high above the ground in the cavity of an evergreen tree. Nests are often lined with soft materials such as leaves, moss, and grass. This little sleeper is using its bushy tail to keep warm, with the help of some lichen and pine needles.
