alternatives presented under i, 2, 3,4, etc. Then 

 take up the subdivisions under a, b, c, d, etc., 

 and so on until the bird is found. If it does not 

 work out correctly keep on with the key, as in 

 many instances the same bird is given two or more 

 times under different headings. The identification 

 should always be verified in the descriptive list. 

 The number following the bird's name in the key 

 corresponds with the number of the bird in the 

 list. In using the key notice that the name of each 

 bird follows the description. An opera glass and 

 a large store of patience are invaluable in identify- 

 ing birds in the field. Even then the value of a 

 key is only relative. It will generally be found 

 helpful with male birds and in some instances may 

 serve in identifying the female also.
