I ___2___ to catch it and found that inside the nest, there was a baby bird. One of the bird’s legs caught on a vine (藤). And the bird was trying to get away from it. Without a second thought, Mum and I decided to help the poor ___3___. We used scissors to cut away the vine and the baby bird was ___4___.

After ___5___ all those things, we wondered whether the baby bird belonged to animals under protection. So we began to search for some ___6___ about the bird online. Half an hour later, we ___7___ found out that it really was. I called the animal protection team for ___8___. As soon as they arrived, they took a careful look at the bird and found it was hurt.

On the second day, I got up early to check on the bird. I saw the baby bird and its parents. The bird was in ___10___ condition (状态) again and was lively!
