bird of night

1. It came to me like the bird of the evening that hurriedly flies across the lampless room from the one open window to the other, and disappears in the night.
   它向我飞来，像夜中的小鸟急遽地穿过无灯的屋子的两边洞开的窗户，又在黑夜中消失了。
2. What you must do instead is to slip the new bird into the chicken coop in the middle of the night while the others are asleep.
   你必须在三更半夜，趁别的鸡睡觉时，把新来的鸡偷偷放入鸡笼中。

noun
