BLACKBURNIAN WARBLER. 



Sylvia Blackburni^, Lath. 



PLATE CXXXV. Vol. II. p. 208. 



" The nest of this species," as Dr T. M, Bkeweb informs me, " is 

 rather loosely constructed, and is formed of dry grass, leaves, and stripes 

 of the bark of the grape vine, with the lining of finer grass and a few 

 horse-hairs. It measures three inches in external diameter, two inter- 

 nally, and is two and a half inches in depth, including the bottom, 

 which is half an inch thick. The eggs are extremely beautiful, having 

 on a white ground dots and lines of reddish-brown, chiefly disposed at 

 the larger end. They measure eleven-sixteenths of an inch in length, 

 and half an inch in breadth ; they have the form of a short abrupt cone. 

 This," he adds, " is the only instance in which I have known it to breed 

 in Massachusetts." 



BAY-BREASTED WARBLER. 



Sylvia castanea, Wilson. 



PLATE LXIX. Vol. I. p. 358. 



Although I have procured a great number of birds of this species 

 of late years, I have not been able to discover its nest. I found it 

 abundant in April and the beginning of May, along the shores of the 

 Gulf of Mexico, as far as Texas, and to the eastward it is not uncom- 

 mon even in Nova Scotia, although my friend Dr Bachman informs 

 me that he has not seen it in South Carolina.
