Best Male Nightingale Vocalists Make Best Fathers
唱的好也做的好
To our knowledge, there’s no correlation between a man’s singing ability and his care and attentiveness as a father. But any Pavarotti among the nightingales will serenade his mate while she sits on her eggs. And after they hatch he will visit the nest about 16 times each hour to feed their offspring. Because, among nightingales at least, the best singers also make the best fathers. So finds a study in the journal BMC Evolutionary Biology. [Conny Bartsch, Michael Weiss and Silke Kipper, Multiple song features are related to paternal effort in common nightingales]
就我们所知，一个男人的唱歌水平和他作为一个父亲的关心和体贴之间应该没啥联系。但是，夜莺中的任何一个帕瓦罗蒂叔叔都会在他的配偶孵卵的时候鸣唱小夜曲呢。而在孩子们破壳之后，他会每小时归巢16次照料他的孩子们。因为，至少在夜莺中，最好的歌唱家等同于最好的老爸。这是一项发表在《BMC进化生物学》杂志上的一片文章得出的结论。
Some 80 percent of birds practice biparental care, meaning both the male and female rear their offspring together. So it’s crucial for a female bird to pick as a mate the most promising father—both genetically and behaviorally. Female birds look for signs of fitness that range from the flamboyant plumage of the peacock to the bizarre dances of birds of paradise.
大约80% 的鸟都是双亲共同照顾子女，也就是说雄性和雌性一起照顾后代。所以嘛，对雌性鸟类来讲，寻找一位能胜任最佳老爸的雄性配偶——不管是遗传基因还是行动力上——都是很重要的一件事。 雌鸟的选择标准从孔雀的绚丽羽毛到天堂鸟的诡异舞蹈多种多样。
And for nightingales, it’s the most elaborate song that apparently wins the day. The average male has some 180 tunes in his repertoire. These avian Sinatras vocalize highly variable song types including buzzes, whistles and trills. And such virtuoso singing seems to signal the female that this is a guy she can count on. That is, when it’s time to help raise the kids, he’s not a flight risk.
对夜莺来讲，就是最精妙的歌声才能成为明显的大赢家。平均来看，雄性夜莺的曲库里大约有180 多种曲调。这些鸟类Sinatras发音上面及其多样化，它们的曲子类型包括嗡嗡叫，吹口哨 和颤音等等。这些歌唱家貌似是要用歌声对雌性倾诉说他们自己是多么的可以依靠。也就等于说，当他们面临抚养孩子的问题时，他可是很靠谱的哦。
