THE WAY TO STUDY BIRDS 



Do not stop at one section until you have read 

 over all, merely because it seems to fit your 

 description. To continue the plan we naturally 

 turn to find which "c" contains the Bluebird's 

 description under "bbbbb." It is easily seen 

 that it is "ccccccc" and then that "ddd" and 

 "dddd" are the next correct headings, which 

 read Bluebird c? (the symbol for the male) and 

 Bluebird 9 (the symbol for the female). 



USE OF KEYS AND SONGS 



Now that you have learned the use of the Key 

 go out of doors and either take the Key with you, 

 or secure a detailed description which you can 

 take home, tho the former course is preferable 

 if practicable. In this way observe and identify 

 five species which you do not already know. 

 Thus you will become thoroly acquainted with 

 the use of the Key and will also learn five new 

 species. 



After this work the best possible course would 

 be to go out and learn five songs with which 

 you are unacquainted. Go outdoors, and when 

 you hear the first new song, hunt for its author, 

 and proceed thus until you have learned five. 

 The Key may be of great use in identifying 

 these songsters if you do not recognize them 

 when they are found.
