270 BIRDS OF NORTH CAROLINA 



The Yellow-throated Vireo arrives in our State from the south about the middle 

 of April, and leaves in September. The song is loud and musical and is continued 

 virtually during the entire period of the bird's stay. While here this bird may be 

 found in mixed woods or in groves of shade trees around houses, and it appears to 

 have a preference for groves of large trees. 



FIG. 217. YELLOW-THKOATED VIREO. 



Its nest is similar to that of the Red-eyed Vireo, but is usually placed at a greater 

 height from the ground. The outside is often ornamented with gray lichens. In 

 true vireo fashion, it is suspended from a fork at the end of a limb, and the eggs 

 are said to have a more roseate tinge, and to be more heavily marked than those 

 of the other members of the family. We have only one record of a nest taken 

 in North Carolina; this was at Raleigh, May 28, 1894. It contained three eggs, 

 and was suspended from a fork at the end of a long limb of a small oak, at a height 

 of eight feet from the ground. 



269. Lanivireo solitarius solitarius (Wils.}. BLUE-HEADED VIREO. 



Description: Ads. Top and sides of the head bluish gray; eye-ring and lores white; back 

 olive-green; greater and middle wing-coverts tipped with white, forming two distinct wing-bars; 

 outer web of tertials edged with whitish; underparts white; sides washed with greenish yellow. 

 L., 5.61; W., 2.96; T., 2.15; B. from N., .28. 



Remarks. This species may be known by its white lores and eye-ring, and bluish-gray cheeks 

 and crown. (Chap., Birds of E. N. A.) 



Range. Eastern North America, breeding chiefly north of the United States; wintering in 

 Mexico and Central America. 



Range in North Carolina. Spring and fall migrant thorughout the State. 



Except that this form occurs with us in both the spring and fall migrations, little 

 can be said about it that does not apply to the next form, nor can the migration- 

 records of the two forms be separated. Seventy-three specimens have been taken 

 at Raleigh on various dates, as follows : January 3 (1891) ; in March and April, and 

 on May 5, 1889; July 27, 1892; in August, September, October, and on November 

 3, 1889; and December 15, 1885. The winter and summer birds, and at least some 

 of the others, might perhaps just as correctly be enumerated in the discussion of 

 the next form.
