species must diminish in numbers. Its song is usually delivered from the 

 top of a cat-tail or some low bush and resembles considerably the trill of 

 the Chipping sparrow, but is not so thin and insectlike and is somewhat 

 more melodious. It has also an ordinary chip similar to that of the Song 

 sparrow. 



Its nest, which is placed on the ground at the edge of the marsh or 

 in a bunch of flags or sedges, resembles very much the nest of the Song 

 sparrow. The eggs are 4 or 5 in number, greenish white or light blue in 

 ground color, rather closely spotted and blotched with brown, more heavily 

 around the large end. Average dimensions .76 by .56 inches. Two broods 

 are usually reared in a season.
