146. VIREO PUSILLUS. 



LEAST VIREO. 



This bird occurs in Arizona, chiefly its lower portion, and 

 California, from Sacramento to Cape St. Lucas. The habits of 

 this Vireo, as far as known, correspond closely with those of 

 Bell's and the White-eyed Vireo. 



Nests from Arizona are described as substantially like those of the 

 former species. The eggs measure about .69 by .56, and are of 

 crystalline whiteness, speckled with red and reddish-brown — the 

 markings being very minute and scarcely discernible in some cases, 

 in others larger and more distinct. 



147. VIREO VICINIOR. 



GRAY VIREO. '* 

 FAMILY Laniidse.— Shrikes. 



148. LANIUS BOREALTS, 



GREAT NORTHERN SHRIKE. 



In the breeding season this species is found throughout the whole 

 of North America north of the United States. The nest is built in 

 trees, and except the base of twigs and stalks, is composed of soft 

 mosses, stems and grasses, thoroughly felted together, and lined 

 abundantly with down and feathers. "The egg measures i.io by 

 .80 and is of a light greenish-ground, marbled and streaked with 

 blotches of obscure purple, clay-color, and rufus-brown. 



149. LANIUS LUDOVICIANUS. 



LOGGERHEAD SHRIKE. 



Habitat, South Atlantic and Gulf States ; North to Mississippi 

 and Ohio Valley. 



This Shrike begins nesting in Ohio about the middle of May. 

 A typical nest before me is a large massive structure made of twigs, 

 roots and stems of plants; an inner nest is made of fine grasses, 

 lined with feathers and a few horse-hairs. It measures six inches
