Birds of Oregon and Washington 3 5 



Color for " Birds Markedly Yellow or Orange," 

 and you will find among them only seven of the 

 thirty-three in the list on size which you have 

 just consulted. The bird must be one of the 

 seven. Find in the Index, in turn, the names of 

 these seven birds ; then refer to the pages where 

 descriptions of these birds are given, and in a 

 few minutes you will have identified your bird. 



Another example : Suppose it were Steller's 

 Jay that you had found ; you would look in the 

 Key for Size for " Birds much larger than the 

 Robin " ; then turn to the Key for Color to the 

 list under " Blue and Bluish." 



At the end of the book will be found two 

 models for making a note-book for writing down 

 descriptions of birds. One, for a " General De- 

 scription," to be used when the bird has been 

 seen only in a general and superficial way ; the 

 other, for a " Particular Description," and to be 

 used for more detailed observations.* The 



*The model for the Particular Description is based upon the 

 " Topographical Bird," to be seen at the beginning of this chapter. 

 The bird is kindly furnished by Mr. F. M. Chapman, in order to 

 enable students in Oregon and Washington to use the " Bird-Lore's 

 Field Identification Blank," prepared by Mr. Chapman, and sold at 

 about cost. For ten cents, these books will be sent postpaid by the 

 J. Horace McFarland Company, Harnsburg, Pennsylvania.
