     If we find a bird nest, we will have a good place of observing(观察) and knowing about birds.
     Birds sit on eggs and take care of their baby birds from April to June. Because the baby birds are
too young to leave the nest, mothers often leave and come back to the nest during the time to look for
food. So it is good to observe birds. When we observe birds, we'd better hide ourselves in a close
place to the nest, and it's better for you to use binoculars(双筒望远镜).
     But how to make a bird nest? It's very easy. If you want to make one, please follow these:
     Making a nest: A good nest must be very fine, strong, thick and easy.
a) Each nest must have six boards. Don't make the boards

too slippery.
b) Dig a small hole in the front of the nest as a door. The "door" is from 3cm to 5cm. So the bird can
fly in or out easily.
c) Make sure the rainwater doesn't go into the nest.
d) One piece of the boards should be easy to open.
e) Please don't forget to color the nest.
