题目是：
Begging by nestlings
Many signals that animals make seem to impose on the signalers costs that are overly damaging.A classic example is noisy begging by nestling songbird when a parent returns to the nest with food.These loud cheeps and peeps might give the location of the nest away to a listening hawk or raccoon, resulting in the death of the defenseless nestlings.In fact, when tapes of begging tree swallows were palyed at an artificial swallow nest containing an egg, the egg in that "noisy" nest was taken or destroyed by predators before the egg in nearly quiet nest in 29 of 37 trials.
非常急.谢谢了.

Begging by nestlings 雏儿乞食
Many signals that animals make seem to impose on the signalers costs that are overly damaging.
很多动物发出的信号对于发信号的动物来讲都会让它们付出完全破坏性的代价.

一个经典的例子就是当成鸟带着食物归巢后巢里的雏鸟就会大声的乞食,这些叽叽喳喳的声音可能就会将巢穴的位置暴露给听到这些声音的鹰隼或是浣熊,导致毫无防备的雏鸟死亡.
In fact, when tapes of begging tree swallows were palyed at an artificial swallow nest containing an egg, the egg in that "noisy" nest was taken or destroyed by predators before the egg in nearly quiet nest in 29 of 37 trials.
事实上,当在一个人工的,装有一枚树雀卵的巢中播放树雀雏鸟乞食的录音带的时候,在29到37次的试验当中,这个放在“吵闹”的巢中的蛋会先于放在安静巢穴中的蛋被掠食者取走或者破坏.
