629c. MOUNTAIN VIREO. Lanivireo soli- 

 tarius alticola. 



Range. Mountains of Carolina and Georgia; 

 winters in Florida. 



Said to be larger and darker than solitariuv 

 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. 



62Qd. SAN LUCAS VIREO. Lanivireo soli- 

 tarius lucasanus. 



Range. Southern Lower California. 



Similar to cassini but with the flanks more 

 yellow. Their nesting habits or eggs will not 

 differ from the others.

Vireo atricapil- 



to Kansas ; 



Range. Central Texas north 



winters in Mexico. Black-capped Vireo 



This peculiar Vireo has a black crown and sides of head, 

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

 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. The 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. 



fi.Sl. WHITE-EYED VIREO. Vireo griseus griseus. 



Range. Eastern United States, breeding from the Gulf to northern United 



States. 



This Vireo has white eyes, as implied by its 

 name, is yellowish green on the sides and with 

 two prominent bars. They have no song, like 

 the other Vireos, but a strange medley of notes 

 resembling those of the Chat or Shrike. They 

 nest near the ground in tan- 

 gled thickets, making large ^ 

 nests for the size of the birds 

 and not always suspended; 

 they are made of weeds, 

 leaves, grass, bark or any 

 trash. Their three or four 

 eggs are laid late in May or White 



early in June; they are white, sparingly speck- 

 led with brown; size .75 x .55.

 maynardi. 



Range. Southern Florida. 



This grayer and paler variety nests in the 



same manner and the eggs are not distinct 



White-eyed Vireo from those of the last form.
