570 HISTORY OF THE 



but their breeding limits are but little known. Mr. Brewer, in 

 "North American Land Birds," gives the following descrip- 

 tion of their nest and eggs (this was before the separation of 

 the eastern representative, D. j^tthnarum hypochrysea^ but the 

 locality identifies the nest and eggs): 



"The Palm Warbler usually selects for the site of its nest the 

 edge of a swampy thicket, more or less open, placing it invari- 

 ably upon the ground. This is usually not large, about three 

 and a half inches in diameter and two and a half in depth, the 

 diameter and depth of the cavity each averaging only half an 

 inch less. The walls are compact, and elaborately constructed 

 of an interweaving of various fine materials, chiefly fine dry 

 grass, slender strips of bark, stems of the smaller plants, hyp- 

 num, and other mosses. Within, the nest is warmly and softly 

 lined with down and feathers. 



"Mr. Kennicott met with a nest of this bird at Fort Resolu- 

 tion, June 18th. It was on the ground, on a hummock at the foot 

 of a small spruce, in a swamp. When found, it contained five 

 young birds. 



"Their eggs are of a rounded oval shape, and measure. 70 of 

 an inch in length by. 55 in breadth. Their ground color is a 

 yellowish or creamy white, and their blotches, chiefly about the 

 larger end, are a blending of purple, lilac and reddish brown."
