OF VIRGINIA 299 
[671]. Dendroica vigorsi (sbudubon). Pine Warbler, 
[Pine Creeper]. 
Raner.—Eastern North America. Breeds in Tran- 
sition and Austral zones from northern Manitoba, northern 
Michigan, southern Ontario, southern Quebec, and New 
Brunswick south to east central Texas, the Gulf States, 
and Florida; winters from southern [linois and coast of 
Virginia to Florida, eastern Texas, and Tamaulipas, and 
easually north to Massachusetts; occasional in Bermuda; 
accidental in British Columbia. 
Many birds winter with us; these I judge to be the 
first to lay. This is our first migratory warbler to arrive 
from the south, and the first to nest. March 13th finds 
them with us and in song, while those that intend breed- 
ing commence nest building almost at once. Non-resident 
birds, though, are in full migration up to, and during, the 
latter part of April. As fully feathered young in nests 
have been found on the 7th of April, some birds must 
be laying by March 15th or 18th. Weather conditions 
seem to have little effect on their breeding time, although 
many uests are blown down by the high winds during 
the first part of April. Tall pine trees are invariably 
selected, the nest either placed on a horizontal limb among 
the cones, or in an upright crotch near the top amongst 
the cones. So well concealed is the nest that even after 
secing the bird fly to it one can not see the nest proper. 
Of course there are exceptions to all cases, and I have 
found them saddled on a lower limb of a pine, ten feet. 
up, without protection of any kind. The song is not 
unlike that of the Chipping Sparrow, though much softer 
and sweeter, and this cause alone kept them from closer
