one mav tranij) the woods for miles witlmut seeing a 

 dozen l)ir(ls. 



Sei)tenil)er is tlie nioiitli of AVarMers. They come in 

 myriads (hirinii; the hitter half of the month, and on 

 favorable nig-hts we may sometimes liear their line-voiced 

 tserps as they Hy by overliead. About the 2r>th of the 

 month onr winter residents, the Jnnco, AVinter AVren, 

 Golden Kinglet, and ]]rown Creeper, will arrive. 



The sunnner residents are now rapidly leaving us. 

 In a general way it may be said tliat 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. Xovember are the months of Sparrows. 

 They rise in loose flocks from every stubble or weed 

 field, and seek shelter in the bordering l)ushy 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 be seen that in 

 reality there are Imt few periods during the year when 

 some event is not occurring in the l)ird world. As we 

 accumulate records for comparison, and learn to ajipre- 

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

 tion will increase and be renewed with the chano^ino: 

 seasons. 



AVe have found, in this brief review, that our birds 

 may be placed in four classes, as follows : 



1. Periiyinent RcHtdenU. — Birds that are represented 

 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. 



?). Whiter lirs/'f/f /its'. — Birds that come from the north 

 in the fall, |)ass tlie winter with us, and return to their 

 more northern homes in the spring.
