haunts of men, to pass the period of breeding and rearing its 

 young in more security. 



The apparent distribution of this species, judged by the records 

 of recent observations, is somewhat pecuHar. It seems to be 

 abundant in the southwestern portion of this Eastern Province, and 

 rarely ranges east of the AUeghanian hills until north of 40°, when 

 it spreads off to the shores of the Atlantic, though seldom going 

 beyond latitude 42°. A few examples only have been taken in 

 Massachusetts, and though common in Ohio it has not been seen 

 in Ontario. Farther west it is found north to the southern por- 

 tions of Michigan, Wisconsin, and Minnesota. It winters south to 

 eastern Mexico and Guatemala. 



The nests that have been discovered in recent years are not 

 fashioned hke that described by Wilson, for instead of being 

 funnel-shaped, they have the ordinary cup-like form. 



Opinions differ regarding the song, but I am inclined to believe 

 that it is a rapid trill of strong, sweet tones, limited m compass and 

 executed with little art, — a merry whistle rather than an artistic 

 melody.
