Ffh. Ffh. Ffh! It was not just the empty nest (鸟巢) of a pewee bird as Amy had found the last five days. Amy ran home through the woods.

“Mum!” she shouted. “I see birds. Two. In cave (洞穴). Beautiful!”

Mum smiled. Birds! Always birds! From the moment Amy woke up in the morning to the moment she closed her eyes at night, she thought only of birds.

Amy climbed straight to her attic room—her museum, she called it. Every shelf, every spare inch of floor, was covered with nests, bird models and natural science books. The walls were covered with pencil and crayon drawings of many different kinds of birds, all signed “Amy in the woods.”

“Are those the same birds who built the nest last year? Will they return to the cave next spring?” Amy always wondered. “I will study my cave birds. I will draw them just as they are.” Amy made up her mind.

In a week, the birds were used to her. They were busy building their nest as Amy watched and drew with her pencils. Soon the dried brown nest became a soft green bed.

Amy watched as two baby birds came out. She watched as the young birds flew for the first time. She began to feel a part of this small family.

When the days grew shorter and the autumn air began to bite, Amy knew the birds would leave soon. But would they come back? She had to know!

In bed that night, she formed a plan.

The next day, when the mother and father birds were away from the nest, she tied something to one leg of each baby bird. A week later, the birds were gone. . .

The days grew longer again. One morning. Amy heard a bird call, “Fee-bee! Fee-bee!”

She ran to the cave. Watching the way the birds flew in and out of the cave, Amy knew her friends came back. But where were last year’s babies? Did they return too? She began to search the woods near the cave, listening for their call.

Inside a little house, she found two birds building a nest. One wore a silver ring around its leg. Up the small river, under a bridge, she found two more nesting birds. And one wore a silver ring around its leg.

Amy smiled and called, “Fee-bee! Fee-bee!”

B She had rich bird-watching experiences.

C She liked drawing more than other hobbies.

D She wanted to keep her hobbies as secrets.

解析：选B。推理判断题。定位第四段阁楼 “博物馆”：房间摆满鸟巢、鸟模型、科普书；墙上满是各类鸟类绘画。说明艾米长期观察鸟类，积累很多，拥有丰富观鸟经历。B 她有着丰富的观鸟经历。A：文中只写她向妈妈呼喊，没有写和妈妈一起研究鸟；C：画画只是爱好之一，没有对比说比其他爱好更喜欢画画；D：没有提到保守秘密，属于无中生有。

B She separated the baby birds from their parents.
