OF VIRGINIA 297 
[667]. Dendroica virens (Ginelin). Black-throated 
Green Warbler. 
Rayexz.—North America. Breeds in Lower Canadian 
and Transition zones from west central and northeastern 
Alberta, southern Manitoba, central Ontario, northeastern 
Quebec, and Newfoundland south to southern Minnesota, 
southern Wisconsin, northern Ohio, northern New Jersey, 
Connecticut, and Long Island, New York, and in the 
Alleghenies south to South Carolina and Georgia; in 
migration west to eastern Texas; winters in Mexico 
(Nuevo Leon to Chiapas and Yucatan), Guatemala, Costa 
Rica, and Panama; occasional in West Indies; acci- 
dental in Arizona, Greenland and Europe. 
April 25th finds these birds passing through Tidewater 
Virginia, and again, moving southward the middle of 
September and until October 15th. Professor Smyth also 
reports them at Blacksburg about the same time in the 
spring, and July immature birds as “possible residents.” 
Like the Blackburnian and Cerulean Warblers, they are 
birds of the coniferous forests, and as a rule build in 
such trees. The nest is placed from eight to forty feet 
up, a neat structure of pine needles, bark fiber and rootlets, 
and lined with hair and sometimes feathers. The eggs 
number four to five, usually four; a creamy ground, 
spotted and specked with dark brown, and minute black 
specks, with fainter undermarkings of lilac, forming a 
wreath around the larger end. Size, .64x.50. Fresh eggs 
May 30th till June 15th. Their food consists of larve, 
spiders, flies, beetles and other insects, taken from the 
foliage of the trees.
