328 ORNITHOLOGY AND OOLOGY. 



This bird can be regarded only as an extremely rare 

 summer visitor in New England, Massachusetts apparently 

 being its northern limit. I have heard of two or three 

 specimens being found in this State, and it is possible that 

 others may have occurred here. 



The nest of this species is placed on the ground, usually 

 in a dry pasture or field, and most generally beneath a tuft 

 of grass or a small bush. It is loosely constructed of grass 

 and fine roots arranged circularly, and with a finer lining. 

 The eggs are four in number : they are of an ovoidal shape, 

 and are but little pointed. Their dimensions vary from .82 

 by .60 inch to .79 by .58 inch: their color is a delicate 

 greenish-blue, without spots or markings. 



I have had no opportunities for observing the habits of 

 this bird, and can present nothing of value with relation to 

 them.
