OF VIRGINIA 285 
[641]. Vermivora pinus (Linneus). Blue-winged 
Warbler, 
Rayoge.—Eastern North America. Breeds from south- 
eastern Minnesota, southern Michigan, western New York, 
Massachusetts (rarely), and southern Connecticut south 
to northeastern Kansas, central Missouri, Kentucky, 
Maryland, and Delaware (casually further south) ; (War- 
wick Co., Va.) ; winters from southern Mexico (Puebla) 
to Guatemala and casually to Colombia; very rare 
migrant in southeastern United States south of Virginia 
and east of Louisiana; occasional in southern Ontario; 
accidental in the Bahamas. 
The 1910 A. O. U. check list does not give this bird’s 
breeding range as far south as the James River Peninsula, 
Va., though by the following can be seen its southern 
breeding range on the coast. 
It is not a common resident with us, although when it 
takes a fancy to a place it seems to return each season 
regularly. Finding two nests with eggs in twenty years 
is not a great record, and those were found in practically 
the same place, at the foot of low bushes in the head of 
a swampy ravine emptying into a mill pond. Both nests 
were found by my father, one with two eggs of the Blue- 
winged Warbler and four eggs of the Cowbird, the other 
set with four eggs, well advanced in incubation. While 
we have worked this particularly likely spot and many 
other suitable places, covering a period of twenty years, 
we have failed to locate other breeding birds with eges. 
They undoubtedly are more abundant as we go further 
northward on the Cape Charles Peninsula. The nests 
were well concealed, besides being partly arched over, 
and composed of fine and coarse grasses, small, narrow, 
dry leaves, and strips of bark; lined with fine grasses.
