THE WAY TO STUDY BIRDS 



takes up the data of a few permanent residents, 

 the use of a bird key, and a few songs. Part 2 

 is devoted to summer birds, Part 3 to tran- 

 sients (i. e., those species which neither breed 

 nor winter in our locality, but stop in the fall 

 and spring en route from their summer to their 

 winter homes), and Part 4 describes the winter 

 residents. One must not forget that the sum- 

 mer part is applicable to most of the spring and 

 fall, as the majority of our birds arrive by the 

 first week in May and do not leave until well 

 into September. This is also true to a lesser 

 extent of the winter residents. 



Each part is arranged with reference to the 

 abundance of a species, so that if all the perma- 

 nent residents are not readily found, as may be 

 the case, it is then better to turn to the appro- 

 priate season before completing Part i . With this 

 single exception sequence is of great importance, 

 for each part of the work is based upon what 

 precedes. If you are not a real beginner in 

 ornithology and therefore know the first part, 

 read thru until you reach the limit of your pres- 

 ent knowledge, at which point proceed to find 

 the bird with which you are unfamiliar and 

 continue thus with the succeeding species.
