Breeds from May to July. The nest is built on the ground and is 

 composed of dry grass, sometimes more or less arched over at the top. 

 The eggs are from 3 to 5 in number, pure white, speckled and spotted 

 with reddish brown, chiefly at the larger end, and occasionally showing 

 small markings of black and dull lavender. They measure about 

 .73 X .56 inches. 



Mr. Frank M. Chapman says: "Its fine insect-like notes give it 

 the name of Grasshopper Sparrow. They may be written pit-tuck, 

 zee-e-e-e-e-e-e-e . Under favorable circumstances they can be heard 

 by an attentive listener at a distance of two hundred and fifty feet, 

 but the casual observer would pass within ten feet of a singing bird 

 and be none the wiser." (Handbook Bds. Eastern N. A., 1895, P- 294)
