 the bird students who have visited the region.

gilva, Lat., yellowish (but it is the least yellowish of our native vireos) 



Description. Decidedly smaller than the Red-eye; upper parts olive 

 green, not so bright as in the Red-eyed vireo, more mixed with gray, especially 

 toward the head, the crown being practically ashy in color but not sharply 

 distinguished from the more olive green of the back, as in the Red-eyed 

 vireo; under parts white, slightly tinged with greenish yellow on the sides; 

 an indistinct white superciliary line and an obscure dusky one through 

 the eye; no wing bars, and no decided markings of any kind; one of our 

 most neutral tinted birds. 



Length 5.5-6 inches; extent 9; wing 2.8; tail 2.25; bill .4; tarsus .65. 



Distribution. The Warbling vireo breeds in eastern North America 

 from southeastern Alberta, northern Manitoba, Ontario and Nova Scotia, 

 to northern Texas, southern Louisiana and North Carolina; winters some- 

 where south of the United States. In New York the Warbling vireo is 

 a common summer resident of the Carolinian and Transition areas, except 

 in the northern and colder portions. It is not quite so generally distributed 

 as the Red-eyed vireo, but undoubtedly breeds in every county of the 

 State with the exception of the interior of the Catskill and Adirondack 

 districts. Mr Batchelder informs me that he has found it nesting in the 

 shade trees of Elizabethtown in Essex county, and Doctor Merriam also 

 found it at Plattsburg and in Lewis county, and I have noticed it about 

 the edges of the Adirondack forest, so that it may nest even in the south- 

 eastern corner of Hamilton county, but no records to this effect are before 

 me.
