To our knowledge, there's no correlation between a man's singing ability and his care and attentiveness as a father.
就我们所知，男性的歌唱能力同他能否成为一位慈爱人父并未有任何关联。

But any Pavarotti among the nightingales will serenade his mate while she sits on her eggs.
但在夜莺这个种族里，任何一位如同帕瓦罗蒂般的男歌唱家都会在配偶孵蛋时为爱鸟哼唱小夜曲。

And after they hatch he will visit the nest about 16 times each hour to feed their offspring.
而孵化后雄夜莺还会每小时16次探望并喂食小鸟。

Because, among nightingales at least, the best singers also make the best fathers.
因为至少在夜莺当中，顶尖歌手也会是模范好丈夫。

Some 80 percent of birds practice biparental care, meaning both the male and female rear their offspring together.
80%的鸟类都是奉行雌雄二鸟共同抚育后代的双亲抚育。

So it's crucial for a female bird to pick as a mate the most promising father—both genetically and behaviorally.
因此对雌鸟而言，不管是基因角而行为角度择偶最为关键的就是寻找一位最有前途的父亲。

Female birds look for signs of fitness that range from the flamboyant plumage of the peacock to the bizarre dances of birds of paradise.
雌鸟择偶的标准通常会从如孔雀般华丽的羽毛到鸟类的奇异舞蹈等等。

These avian Sinatras vocalize highly variable song types including buzzes, whistles and trills.
这些鸟中的辛纳屈能够发出包括蜂鸣、哨音及颤音在内的多变音调。

And such virtuoso singing seems to signal the female that this is a guy she can count on.
而这样的艺术大师无疑是向雌鸟发出这就是终身伴侣的信号。
