 nest taken in its original undisturbed position in the grass. The eggs are 

 bluish white, speckled and marked in zigzag lines with dark brown. They 

 are decidedly oriole-like in appearance. They are more than four fifths of 

 an inch long, and a little over three fifths of an inch broad. 



The birds breed from Southern New Jersey north to Nova Scotia in

 just inside of it, the portion above and on -the sides of the head forming 

 the so-called horns. The region in front of the eye is black, and broadens 

 below the eye so as to be triangular in shape. The throat is sulphur yellow,'
