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(躲藏)ourselves in a close place to the nest, and it's better to use binoculars(双筒望远镜)．
But how to make a bird nest? Picture 1 and Picture 2 are two kinds of bird nests．Picture 3 gives you some other kinds of bird nests．They are very easy to make．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(光滑)．
