244 | BIRDS—SYLVICOLIDA. 
Regular spring and fall migrant. Common. The Nashville Warbler 
is to be found from the’first to the twenty-fifth of May in woodland and 
along the banks of streams, sometimes singly at other times in sn all 
flocks. Its song is a short warble, more varied and less emphatic than 
that of other members of this genus. Its note is a sharp chirp, which 
Wilson compares to the noise made by striking pebbles together. In Sep- 
tember when on its southern migration it is more common, frequenting 
weeds in woods and on the borders of streams and swamps. At this time it 
is much on or near the ground, and often associates with Tennessee War- 
blers, which exceed them in numbers in the fall. It breeds in the lati- 
tude of Massachusetts and northward. The nest is placed on the ground, 
composed of moss and grasses. ‘The eggs measure .59 by .50 and are white, 
thickly marked with purplish brown spots.

Rare spring and fall migrant. J can record but three specimens taken 
-in the State. Mr. R. K. Winslow took a fall specimen in the vicinity of 
Cleveland, previous to 1861. In May, 1875, I tooktwo specimens. Iwas 
attracted to the first, which was perched upon the top of a vine-crowned 
stub, in a woodland thicket bordering a swamp, by its loud, emphatic, 
and rather monotonous song, resembling as nearly as I can describe the 
syllables checky-tick tick tick-tick. This song was louder and more decidedly 
emphasized than that of any other member of the genus with which I 
am acquainted, Two or three days after, 1 took a female, in another 
locality, near this city. Others were seen in company with this last, but 
not secured. 
In the State of Illinois they are said by Mr. Ridgway to be regular mi- 
‘grants, and further westward they are abundant. The nest and eggs 
were discovered by Mr. Kennicott, in the vicinity of Great Slave Lake. 
The nest, like those of all other members of this genus known, is placed 
on the ground.. It is composed of strips of bark, stems and grasses. The
