Black Vulture


　　For black vultures, enforcing monogamy is a family affair: If caught having * with a bird other than its partner, the vulture gets harassed by not only its mate, but by other vultures in the area.
　　
　　黑秃鹰
　　对黑秃鹰而言，一夫一妻制是需要强制执行的。如果有黑秃鹰被发现和配偶以外的异性发生性关系，它们不但会遭到配偶的惩罚还会受到周围其它秃鹰的攻击

Penguin

　　After the movie "March of the Penguins" came out, many conservative groups cited Emperor penguins as role models for monogamy. While it's true that these flightless Antarctic birds pair up to copulate and raise young, they only stay together for one mating season, after which they normally switch partners.
　　
　　企鹅

　　当影片《帝企鹅日记》播出后，许多人都将帝企鹅奉为单配偶动物的典范。事实上，在交配季节里，企鹅只有一个性伴侣且夫妇共同哺育幼崽，但他们的忠贞只能保持一个交配季节。等到了下一个交配季节，它们通常还会寻找新的伴侣

Anglerfish

　　This deep-sea fish takes monogamy to a bizarre new level. When mating, a male anglerfish bites into the flesh of his female mate, attaching to her body. His mouth fuses with her skin, and their bloodstreams merge. Once joined, the male degenerates until he's simply a source of sperm for the female. A female will often have several males attached to her at once.

　　琵琶鱼

　　生活在深海中的琵琶鱼有十分奇特的一夫一妻制。雄鱼交配时会在雌鱼侧腹部咬一口。雌鱼从体内释放的一种特殊酶让雄鱼的嘴和雌鱼的皮肤结合在一起，且雄鱼和雌鱼的血液开始流通。一旦结合为一体后，雄鱼便会不断萎缩，直至成为雌鱼体外能产生精子的生殖腺。一条雌性琵琶鱼通常会同时被数条雄鱼附体

Wolf

　　Like penguins, wolves practice serial monogamy, meaning they can have several mates throughout a lifetime, but only one at a time. A female wolf will typically mate with one male, but will take another if her mate dies, gets kicked out of the pack or is so injured or sick that he can't breed.

　　狼

　　和企鹅一样，狼会在不同阶段有不同的伴侣，这意味着它们一生会有多个伴侣，但一个阶段只有一个。而母狼基本上都只与一只公狼交配，除非这只公狼死掉、被逐出狼群或是因受伤和体弱等原因不能繁殖后代


Bald eagles

　　The poster birds for fidelity, bald eagles are monogamous and remain faithful to each other until one dies. Recent studies of DNA from the feathers of other eagle species support the idea that monogamy is the norm among raptors.

　　白头秃鹰

　　白头秃鹰是忠贞不渝的象征，它们不但保持着一夫一妻制，且直到配偶死去前都不会有其它性伴侣。近期的研究表明，对鹰类雄性的DNA检测证实，肉食鸟类动物基本上都是单配偶动物。
