TIMES OP MIGRATION. 53 



one may tramp the woods for miles witliont seeing a 

 dozen birds. 



September is the month of Warblers. They come in 

 myriads during the latter half of the month, and on 

 favoral)le nights we ma}' sometimes hear their iine-voiced 

 txeejhi as they fly by overhead. Alwut the 2.5th of tlie 

 month our winter residents, the Juneo, Winter ^7ren, 

 Golden Kinglet, and Brown Creeper, will arrive. 



The summer residents are imw rapidly leaving us. 

 In a general way it may be said that the last birds to 

 arrive in the spring are the first to leave in the fall, 

 while the earliest spring migrants remain the longest. 



October and November are the months of Spai'rows. 

 They rise in loose flocks from every stubljle or weed 

 field, and seek shelter in the bordering Imshy growth. 

 Should the season prove warm, many of these hardy 

 seed-eaters will stay with us well into December, but at 

 the first really cold weather they retreat southward. 



This completes the merest outline of the move- 

 ments of our migratory birds. It will l)e seen that in 

 reality there are but few periods during the year when 

 some event is not occurring in the bird world. As we 

 accumulate records for comparison, and learn to appre- 

 ciate their meaning, our interest in the study of migra- 

 tion will increase and be renewed with the changing 

 seasons. 



We have found, in this Ijrief re\'iew, that our l)irds 

 may be placed in four classes, as follows : 



1. Permanent Residents. — Birds that are rejDresented 

 in the same locality throughout the year. 



2. Summer Residents. — Birds that come to us in the 

 spring, rear their young, and depart in the fall. 



3. Winter Residents. — Birds that come from the north 

 in the fall, pass the winter with us, and return to their 

 more northern homes in the spring.
