of loosely interwoven strips of bark of the ‘mountain’ mahogony,” fine grasses, mosses, 
and slender rootlets, and was lined with the fur of some small quadruped. The eggs 
were four in number, the ground-color of the same being white, with a slight roseate 
tinge; they were profusely spotted with numerous small blotches and dots of purplish- 
brown and lilac; especially at the larger end. 
Mr. Aiken found Virginia’s Warbler in various parts of Colorado, especially 
along the eastern base of the mountains, where, in its favorite haunts, it sometimes 
outnumbers all the other Warblers put together. It is ashy and timid species, generally 
darting, with its sharp notes of alarm, into its place of concealment when approached. 
In summer, it frequents the scrub of the hill-sides, at an elevation up to about 7,500 
feet, but during the migrations it is found alternately in the pine forests and among 
the cotton-woods and willows along the streams. ‘‘The male is very musical during the 
nesting season, uttering his sweet ditty continually as he skips through the bushes in 
search of his morning repast; or having satisfied his appetite, he mounts to the top of 
some tree in the neighborhood of his nest, and repeats at regular intervals a song of 
remarkable fullness for a bird of such minute proportions. ... No bird with which Iam 
acquainted conceals its nest more effectually than this Warbler. This is placed at a 
tussock of grass among oak-bushes, being sunk in a hollow scratched in the earth, so 
that the rim of the nest is on a level with the surface. The overhanging grass of the 
tussock hides all so completely that the nest is only to be discovered by the most care- 
ful and persistent search. About the 1 of June, five white eggs, delicately speckled with 
reddish-brown are laid.” -

“Aap HE NASHVILLE WARBLER is a common bird in many parts of our country 
¢ 9 during the migration, especially in the East, from the Atlantic to the Mississippi 
and the Plains. It breeds from northern Illinois northward. In New England it is 
chiefly limited southward in the breeding season by the Alleghanian Fauna, though it 
also nests sparingly in the Carolinian, as far as the mountain regions are concerned. 
In Texas I observed these birds always in the first and second week of April, and in
