THE WHITE-EYED VIREO. 275 



selected a blade of grass. Returning by the same route, they 

 moved so slowly from one tree to another, that my patience was 

 severely tried. Two other days were consumed in travelling for 

 the same kind of grass. On the seventh, I saw only the female at 

 work, using wood and horsehair : the eighth was almost entirely 

 spent by both in smoothing the inside. They would enter the nest, 

 sit in it, turn round, and press the lining. In the course of five 

 days, an equal number of eggs were laid : they were small, of a 

 rather narrow oval form, white, thinly spotted with reddish-black 

 at the larger end. The birds sat alternately, though not with regu- 

 larity as to time ; and, on the twelfth day of incubation, the young 

 came out. I observed that the male would bring insects to the 

 female, and that, after chopping and macerating them with her 

 beak, she placed them in the mouth of her young with a care 

 and delicacy which were not less curious than pleasing to me." 



This account is so full and complete that I can add noth- 

 ing to the history of the breeding habits of thfs bird. But 

 one brood is reared in the season in this latitude. The 

 dimensions of four eggs in my collection from different 

 localities are .83 by .56 inch, .80 by .56 inch, .78 by .54 

 inch, .78 by .53 inch. These will be found to be the aver- 

 age size of this species. The nest is about three inches in 

 exterior diameter, and about two and a half in depth.
