214 NORTH AMERICAN BIRDS. 



inches in diameter by two and one half in height, with cavities unusually 

 large anil deep for the size of the uests. They were wrought almost entirely 

 of long strips of tliin flexible bark, strongly and firmly interwoven. The 

 outer portions consisted of coarser and longer strips, the inner being much 

 finer and more delicate. Witli the outer portions were also interwoven bits 

 of mosses, lichens, and the outer bark of deciduous trees. The entire fabric 

 was a remarkable one. 



The eggs measure .70 by .55 of an inch, have a pinkish-white ground, 

 blotched with jnnple and brown of various shades and tints. They are dis- 

 jiosed chiefly about the larger end, usually in a ring. The eggs are oval iu 

 shape and slightly pointed at one end.

Hau. Kentucky. 



This sjjecies continues to be known only by the description and figure of 

 Audubon. 



Judging from tlie description, tliis species is closely related to /'. Ilip-inn, 

 but .seems to be distinct in tlie jjure bltick of the top of the licad, tlie ab.senoe 

 of omnge-brown on the cheeks, tlie white of the wing being on tlie middle 

 coverts instead of the greater, i\nd the tail-feathers being yeUowish-grtu'n ; 

 the outer web of outer feather white, instead of a large spot on the inner 

 web, etc. The back ajtpears more distinctly .streaked. 



llAItiTS. Two .sjiecimens of this Warbler, obtained near Heiider.son, Ky., 

 May, 1811, by Mr. Audubon, are all its chiim to be recognized lus ii good 

 s]H'cies. N(mc have since been seen. These birds are descrilu'il as having 

 been busily engaged in collecting insects among the branches of a dogwood 

 tree. Tlieir motions were like tiiose of other Warblers. Tliis is all we its 

 yet know as to the history of this species, and its claims to be regiirded as 

 a good and distinct species are involved in doubt.
