FINCHES, SPARROWS, ETC. 293 



The song is insignificant a weak, musical little trill following a 

 grasshopperlike introduction is of such small volume that it can be 

 heard but a few rods. It usually resembles tslp-tslp-tslp 1 see-e-s'r-r-r. 

 More singing is heard toward sunset, when of a quiet evening the 

 trills are audible at greater distances. Each male seems to have a 

 number of favorite perches, weeds or fence posts, which are visited as 

 inclination dictates, but he is of too restless a disposition to remain 

 long on any of them. The most familiar note is a sharp tstp of alarm 

 or expostulation heard during migration, but so constantly employed 

 by both sexes in the breeding season, even on slight provocation, that 

 one gets to think of them as veritable scolds. 



They are more likely to be mistaken for the Vesper Sparrow, which 

 they resemble even in flight, than for any other except perhaps the 

 Ipswich and Sharp-tailed Sparrows. J. DWIGHT, JR.

Few common birds maybe more easily overlooked than the Yellow- 

 winged Sparrow. Its terrestrial habits and weak notes place it among 

 the birds that you are not likely to find unless you know how and 

 where to look for them. I remember once introducing this bird and 

 its song to a visiting ornithological friend. On returning to his home,
