Migration and Distribution of North American Birds. 177 



MIGKATION AND DISTRIBUTION OF NORTH AM- 

 ERICAN BIRDS IN BROWN AND OUTAGAMIE 

 COUNTIES. 



By S. W. WiLLARD, West De Pere, Wis. (1883.) 



This paper was prepared from recorded observations. It 

 gives a systematic series of facts from which the general- 

 izations of Messrs. Baird and Allen may be again applied.* 



Brown County is well adapted for such a system of ob- 

 servation. The warm, short summers succeeded by the 

 long cold winters mark distinctly each movement. The 

 vernal and autumnal movements through these counties are 

 large, thousands of migrants of species that are to some ex- 

 tent summer residents, pass us on their way to less crowded 

 areas. These with the other migrants swell the throng to 

 numbers almost incalculable. 



To facilitate this study I have arranged the species in di- 

 visions based upon their migratory habits while in these 

 counties. 



Class I. Birds that are represented in this section 

 throughout the year, but whose numbers vary in the differ- 

 ent seasons. Members of this class may properly bo called 

 "residents."'
