270 Trees, Stars, and Birds 



A notebook will be useful also in keeping a list of the 

 birds you see and various things you notice about their 

 habits. Record the date, weather, locality where found, 

 and any observations that interest you. If the notes 

 you make outside are written up more carefully after 

 you return home and before you go on another trip, 

 they will be interesting and useful to you at various 

 times, perhaps for years to come. 



The birds described in the following pages are those 

 that are most likely to be seen in the eastern and middle 

 parts of the United States and Canada. However, not 

 many of them may be seen at all seasons, and it is better 

 to study each kind when it can be observed than to 

 follow invariably the order in the book, where they are 

 arranged according to their relationships to one another. 

 It is not important to study every bird that is mentioned 

 in the book. If you answer half the questions by means 

 of your own observation, you will have acquired some 

 real knowledge of birds.

The teacher should write to the National Association of Audubon 

 Societies, 1974 Broadway, New York City, for information about the 

 work of the Association and the literature prepared by it. For two 

 cents each, leaflets giving colored pictures and full descriptions of all 

 our common birds can be secured from the secretary, and assistance is 

 also given in the organization of classes of school children for bird 

 study. Several valuable bulletins on birds may be obtained by writing 

 to the Secretary of Agriculture, Washington, D. C. Some of the states 

 have published excellent books on the birds found within the borders of 

 the state, and in large public libraries a great variety of bird books can 

 be found.
