It had taken me months to get up the nerve to finally do it. As I climbed higher and higher, I decided that looking down was not the best choice. I knew that a small house, built ten years ago by a father and son, awaited me at the top. Only a few feet away from my goal, a branch slipped below me, and I scraped the length of my arm on the bark. I hesitated and looked down. I quickly decided that I was so much closer to the wooden shack than I was to the ground and kept going. I finally reached the top, with a group of my friends cheering for me—I had finally been enough of a risk taker to join them, and they were excited. But not as excited as I was! Why is the narrator most likely climbing the tree?

 Bird nests come in all shapes and sizes. There are many factors that influence the building of a bird’s nest. Birds gather building materials from the region where they live. So, nests in different regions will look different. A bird’s features also play a role in how it builds its nest. Birds with strong beaks can carve a nest out of wood. If the bird has a softer beak, it might gather leaves or straw. Bird nests are as different as the birds who build them. What is the main idea of this passage?

• There are many different types of bird in the world.

• Birds' beaks can influence the way their nests are built.

• Different types of birds build different types of nest for a variety of reasons.

• If we understand birds and the nests they build, we can come up with new ways to build our own homes.
