Male nightingales use singing virtuosity(精湛技巧) to signal prospective(未来的) mates that they will be the most doting(溺爱) dads.
To our knowledge, there’s no correlation(相关) between a man’s singing ability and his care and attentiveness(注意力) as a father. But any Pavarotti among the nightingales will serenade(小夜曲) 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(后代). Because, among nightingales at least, the best singers also make the best fathers.
Some 80 percent of birds practice biparental (双亲)care, meaning both the male and female rear(养育) their offspring together. So it’s crucial for a female bird to pick as a mate the most promising father—both genetically and behaviorally(行为). Female birds look for signs of fitness that range from the flamboyant (艳丽的)plumage(翅膀) of the peacock(孔雀) to the bizarre (奇异的) dances of birds of paradise.
And for nightingales, it’s the most elaborate(精心制作) song that apparently(显然) wins the day. The average male has some 180 tunes in his repertoire(全能节目). These avian(鸟) Sinatras vocalize(发声) highly variable song types including buzzes, whistles and trills(颤声). And such virtuoso(艺术品鉴赏家) 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(飞行险).
疑难句：
1. Some 80 percent of birds practice biparental (双亲)care, meaning both the male and female rear(养育) their offspring together.
v-ing作伴随状语，meaning作伴随状语
2. And such virtuoso(艺术品鉴赏家) singing seems to signal the female that this is a guy she can count on.
That引导的定语从句，修饰female.
3. And for nightingales, it’s the most elaborate(精心制作) song that apparently(显然) wins the day.
That引导的定语从句，修饰song.
段落大意：
雌性夜莺唱歌唱得比较好，他们通过自己的歌声吸引雄性夜莺。雌性夜莺不仅歌唱得好，而且很溺爱自己的孩子，他们会让自己的伴侣感觉到自己可以依靠，可以很好的照顾孩子。
好了，以上就是前程百利小编为大家整理的托福听力生物类-夜莺。相信大家一定有所收获，希望能在备考的路上助大家一臂之力。最后，小编祝大家在托福考试中取得好成绩!
