Title: A kind of habitat segregation
One day I noticed some wondering when I wake up in the early morning. Firstly, one kind of birds tweeted each other, and they stopped it. Then another kind of birds started to chatter. After a while, another kind of birds squeaked. For example, it starts to Crows, and turn to sparrows, and Pigeons (3)coo. I almost didn’t hear they sang at the same time in the early mornings. If I were a bird scholar, I know the reason (4) like the back of my hand!
However, I didn’t give up to think why. I found the (1)corresponding situation on the internet. It’s a kind of habitat segregation. They change the active time because they instinctively avoid useless battle even if they live the same place. This strategy is also helpful for humanity, I guess. For instance, I like commute earlier morning than other employees because the rush hour trains are too tough. Anyway, this result of research (2)coped my curiosity.
homework: (1)correspond, (2)cope, (3)coo
Expression: (4) (like the) back of one’s hand
If you know something like the back of your hand, you are very familiar with it and know it in detail.
