286 North American Birds Eggs, 



628. Yellow-throated Vireo. Vireo flavifrons. 



Range. — United ^States east of the Plains, breeding from the the Gulf to Mani- 

 toba and New Brunswick. 



This handsome bird is wholly unlike any others of the 

 Vireos, having a bright yellow throat and breast; the upper 

 parts are greenish and the wings and tail gray, the latter with 

 two white bars. They are fairly common breeding birds in 

 northern United States, placing their handsome basket-like 

 structures in forks of branches and at any elevation from the 

 ground; the nests are like those of the preceding Vireos but 

 are frequently adorned on the outside with lichens, thereby 

 adding materially to their natural beauty. The four or five 

 eggs are pinkish or creamy white, speckled about the large end with reddish 

 brown. Size .80 x .HO. 



629. Blue-headed Vireo. Solitary Vireo. Vireo solitarius. 



Range. — Eastern United States, breeding from southern New England and the 

 northern states north to Hudson Bay; winters in the Gulf States and south- 

 wa rd . 



A beautiful Vireo with a slaty blue crown and nape, greenish 

 back, white wing bars and underparts, the flanks being washed 

 with greenish yellow; a conspicuous mark is the white eye 

 ring and loral spot. They build firm, pensile, basket-like 

 nests of strips of birch and grapevine bark, lined with fine 

 grasses and hair, suspended from forks, usually at low 

 elevation and often in pine or fir trees (of some twenty nests 

 that I have found in New England all have been in low [White.] 

 branches of conifers). Their three or four white eggs are specked with reddish 

 ))rown. Sixe .80 x .60. 

 629a. Cassin Vireo. T^. s. cassinii. 



Range.— United States west of the Rockies; north to British Columbia. 



Similar to the last but with the back grayish. The nests and eggs of 

 form are in all particulars the same as those of the eastern Solitary Vireo. 

 629b. Plumbeous Vireo. T'. .S'. plumhcus. 



Range.— Rocky Mountain region, breeding from Mexico to Dakota 

 Wyoming. 



Like the Blue-headed Vireo but with the yellowish wholly replaced by leaden 

 gray. The nesting habits of this common variety are the same as those of the 

 last and the eggs are indistinguishable in all respects. 

 629c. Mountain Solitary Vireo. V.s. alticola. 



Range. — Mountains of Carolina and Georgia; winters in Florida. 



Said to be larger and darker than solitarius proper. From all accounts, the 

 habits, nests or eggs of this species differ in no wise from many of those of the 

 northern Solitary Vireo, whose nests show great variations in size and material. 

 629d. St. Lucas Solitary Vireo. V . s . lucasanus . 



Range. — Southern Lower California. 



Similar to fa8-s//(/ but with the flanks more yellow. Their nesting 

 eggs will not differ from the others. 



630. Black-capped Vireo. Vireo afrirapiUus. 

 Range. — Central Texas north to Kansas; winters in Mexico. 



This peculiar Vireo has a black crown' and sides 

 broken by a white eye ring and loral stripe; upper parts 

 below white. They appear to be fairly common in certain 

 localities of their restricted range, and nest at low elevations in 

 mesquites or oaks, placing the nests in forks the same as other 

 Vireos; they are of the ordinary Vireo architecture, lined with 

 grasses. Tlie three or four eggs are pure white, unmarked. Size 

 .70 X .50. Data.— Comal Co., Texas, May 21, 1888. 4 eggs. Nest 



located in a scrub Spanish oak, 5 feet from the ground. Collector, G. B. 



Benners (Crandall collection).
