I did get one and put it in my cage. I felt very happy and looked 3. to some beautiful songs from it. On the next day, its mother flew to the cage with food. The baby bird 4. everything. I was happy to see this. Surely the mother knew 5. her baby liked better than me.

The next morning, I found the baby bird dead. What was wrong? I took 6. care of the bird. Arthur Wayne told me the reason. ＂A mother bird, finding 7. baby in a cage, will sometimes bring it some poisonous(有毒的) strawberries. She thinks it is 8. for it to die than to live in a cage.＂

Never since then have I caught any living birds or 9. it in a cage. It made me know following 10. rules in nature sometimes means everything to the living things.
