 and ashy; breast, rusty brown, spotted with black; belly,

 upper parts are a pale gray with black- centered feathers 

 and the entire under parts are white. 



The nest is made of hay and decayed leaves. The eggs 

 are four in number, of a brownish olive with spots of 

 dark olive brown, and one and two-fifths by nine-tenths 

 of an inch in size. 



The birds breed in the far north and spend the winter 

 in the southern Atlantic states and South America. 

 They are abundant in New Jersey from April 18 to June 

 1 and again from September 14 to October 16, being gen- 

 erally found along the sea coast and rarely on mud flats 

 near bays. 



Their food consists of minute shellfish and insects left 

 by the tide.
