The eggs of this species, some half-dozen or upward, 

 about .60 x -48, are a delicate flesh color, very finely specked 

 and sprayed all over with reddish-brown, thickening into a 

 wreath or large spot at the large end. 



About five inches long, this Wren is deep brown, crossed 

 with bars of black above, the head and neck being plain; 

 the throat and breast are buff, or a light clay color; belly
