Camouflage 伪装

the disguising of military personnel, equipment, and installations by painting or covering them to make them blend in with their surroundings.

伪装是动物用来隐藏自己，或是欺骗其他动物的一种手段，不论是掠食者或是猎物，伪装的能力都会影响这些动物的生存几率，主要的方式包括了保护色、警戒色和拟态。

Scavenger 食腐动物

an animal that feeds on carrion, dead plant material, or refuse. 以腐肉、死去的植物材料或垃圾为食的动物。

食腐动物是指主要靠进食被残留的尸体和腐肉——而不是新鲜杀死的猎物——来获取肉食维生的动物，比如秃鹫、秃鹳、鬣狗、狼獾、豺、蛆虫等。事实上绝大部分的掠食性动物都会在缺乏食物的时候食腐。另外亦有以腐木、腐植质维生的草食性食腐动物，称为食碎屑动物，通常都是无脊椎动物，比如蚯蚓、马陆、䖴虫、蛞蝓、潮虫等。

Biology class: Snowshoe hare’s adaptation to the environment(100%)

The snowshoe hare is a rabbit animal.

First, it uses camouflage to survive in its environment. When the daylight becomes shorter, its fur turns from brown to white. Because land is often covered with snow in the winter, the white color could be like snow, and it’s harder for predators to find it.

Another special thing is that snowshoe hares don’t need to keep fat or store food during the winter, because food is easily available and reachable.

Although I probably should mention that technically a hare is not exactly the same as a rabbit, even though it is very similar the primary difference is that a rabbit’s young are born blind and without fur, while a hare’s babies are born with a full coat and able to see.

Now, another advantage related to this is that unlike many animals in winter, snowshoe hares can stay lean and light weight(保持苗条和体重轻).

Albatross(sea birds nest on islands)

Albatross are seabirds that nest on islands and forage(饲料) for food out in the open sea.

How did they find food and come back in such a long distanct. Unknown, hard to research.

seasonal migration. 季节迁徙

foraging trip. 觅食旅途

Professor: Now usually when we talk about birds flying long distances, we’re discussing seasonal migration.

教授：现在通常当我们谈论鸟类长距离飞行的时候，我们讨论的就是季节性迁徙。

But there’s some species that fly long distances not as part of a migration but as part of their regular foraging for food.

但也有一些物种飞跃长距离不是迁徙的一部分，而是常规觅食的一部分。

A great example is the albatross.

一个很好的例子就是信天翁。

So we’re thinking that albatross could make use of two different kinds of compasses if you will, a magnetic compass and a celestial compass.

所以我们认为信天翁可能利用了两种不同的指南针（如果你愿意这么称呼的话），磁罗盘和天文罗盘。

But the problem is that we’ve also found magnetite in non-migratory birds, which suggests that it may in fact serve a completely different function,

但问题是，我们在不迁徙的鸟身上也找到了磁铁矿，这表明它可能实际上提供一个完全不同的功能
