270 ORNITHOLOGY AND OOLOGY. 



engaged in building their nest in the covered and secluded parts of 

 the forests. I found several of their nests placed on bushes not 

 above ten feet from the ground, without any appearance of choice 

 as to the tree, but generally towards the top, and placed in a fork. 

 The nest is as large as that of the Robin, and is composed exter- 

 nally of coarse grasses, leaves, and moss ; internally of fibrous roots, 

 over which is a bed of the feathers of the wild turkey and pheas- 

 ant (Tetrao umbellus)" 



Nuttall, in describing the nest, says that it is "large and 

 compact, in the fork of a small tree, and sometimes in an 

 apple-tree, composed externally of dried grass, with whitish 

 moss, and well lined with feathers." 



The eggs are from four to six in number, of a dirty lead- 

 colored white, and marked more or less thickly, around the 

 greater end, with dashes and spots of brown of different 

 shades. Dimensions of four eggs : 1.12 by .80 inch, 1.12 

 by .78 inch, 1.08 by .78 inch, 1.04 by .77 inch.
