WARBLERS. 6l 



III. DENDRCECA PINUS. 



PINE-CREEPING WARBLER. 



Habitat, Eastern United States to the Lower Missouri, North to 

 Canada and New Brunswick. 



The nest is built in pine trees and is made of a variety of soft 

 vegetable substances, plant-down, &c , usually mixed with fine 

 rootlets, and often with hair or feathers, and set on a foundation 

 of coarse fibrous and w^dy material. It measures about three 

 inches across by two deep, and generally presents a pretty firm 

 brim of circularly disposed fibres. 



Dr. Brewer describes the eggs as of a rounded oval shape, with 

 an average diameter of .72 of an inch, a breadth of ,55. "The 

 ground-color is a bluish-white. Scattered over this are subdued 

 tintings of a fine delicate shade of purple, and upon this are dis- 

 tributed dots and blotches of a dark purplish-brown, mingled with 

 a few lines almost black," 



112. DENDRCECA MONTANA. 



BLUE MOUNTAIN WARBLER. ** 



113. DENDRCECA PALMARUM. 



RED-POLL WARBLER. 



Habitat, Mississippi Valley (north to Great Slave Lake) and West 

 Indies. Casual in certain Atlantic States. The nest and eggs of 

 this variety are doubtless the same as those of the following species. 



113a. DENDRCECA PALMARUM HYPOCHRYSEA. 



YELLOW RED-POLL WARBLER. 



Habitat, Atlantic States. 



The nesting site chosen by this bird is said usually to be the edge 

 of a swampy thicket, more or less open, placing it invariably on the 

 ground. The nest is small, compactly and elaborately constructed 

 of an interweaving of various fine materials, chiefly fine dry grasses, 

 slender strips of bark, stems of the smaller plants, hypnum, and 

 other mosses. 'Within, it is warmly and softly lined with down 

 and feathers.
