36 NESTS AND EGGS OF NORTH AMERICAN BIRDS. 



high up as fifty feet. It is made of vegetable fibres which are bleached to 

 a uniform wood color, firmly fetted together; the lining is of grass, some- 

 times mingled with horse-hairs and bits of newspapers. 



Hab. Chiefly Eastern North America to Hudson's Bay; Greenland; west to Rocky Mts., and even 

 beyond; Washington Territory ; Utah. 



139. Warbling Vireo — vireosylvia gilva. Spotted and sometimes 

 blotched at the larger end with brown and reddish-brown on a clear white 

 ground — sometimes over the surface will be found small specks of reddish- 

 brown; the complement of eggs ranges from three to four, size .70 to .75 

 in length by about .55 in breadth. This Vireo breeds abundantly from 

 Virginia to Nova Scotia and in all the Northwestern States. West of the 

 Rocky Mountains it is replaced by variety V. g. Szvainsoni. The nest is a 

 beautiful structure that hangs like a little basket between the small twigs, 

 like that of the Red-eye, but is usually at a very considerable distance 



from the ground. Hab. Temperate Eastern North America; west to the high plains. 



139a. Western Warbling Vireo — vireosylvia gilva swainsoni. Eggs 

 in my collection are the same as those of the preceding species. The 

 nests are similar in construction, except probably in the material used. 



Hab. United States from Rocky Mts. to Pacific coast. 



140. Yellow-throated Vireo — lanivireo flavifrons. White, marked 

 with spots of rosy brown. The eggs of this Greenlet are not distinguish- 

 able with certain!}' from those of the Red-eye and Warbling Greenlets — 

 on an average they may be more heavily marked. It breeds throughout 

 its United States range. The nest is more highly finished than those of 

 the other Vireos, being elegantly adorned on the outside with lichens, like 

 a Humming Bird's or Blue-gray Gnatcatcher's nest. Like the others, it is 

 pensile and placed in the fork of a horizontal branch, from three to fifteen 

 feet above the ground. 



Hab. Eastern U. .S. and British Provinces; west to Iowa and Kansas; south to Mexico. 



141. Blue-headed Vireo — lanivireo solitarius. White, less crystal- 

 line than the other Vieros, pretty uniformly spotted over the eggs with 

 dark red and reddish-brown, approaching black, oval in form, size .78 to 

 .80 in length by .55 to .57 in breadth, four in number. This Greenlet is 

 found in northern United States during the breeding season. The nest is 

 more loosely constructed than that of the other Vireos and contains more 

 variety of materials. It is usually placed within twelve feet of the ground. 



Hab. United States and Canada; south to Central America. 



142. Black-capped Vireo — vireo atricapillus. Spotless dull white, 

 ovoid in shape; three or four in number, they measure about .67. by .52, 

 with slight variations in size. As far as known, all the specimens of this 

 rare bird that have been taken are from Mexico, Texas and Kansas. The first
