258 SINGING BIRDS. 
Dr. Bachman, these birds breed in South Carolina, as he saw a 
pair and their young near Charleston. 
This species is common in the Gulf States, and ranges along the 
Mississippi valley, being peculiarly abundant in southern Illinois 
and southwestern Indiana, but near the Atlantic is rarely seen 
north of Georgia. A few stragglers have been encountered in 
New England, while one has been taken at St. Stephen, New 
Brunswick, by Mr. George A. Boardman, and another near Hamil- 
ton, Ontario, by H. C. MclIlwraith. 
It is said to be more deliberate and thrushlike in its movements 
than are its sprightly congeners, the Dendroice. The song most 
frequently heard is described as a simple but pleasing whistle, like 
that of the solitary Sandpiper, though when the singer is near at 
hand, almost startling in its intensity. Mr. Brewster mentions 
hearing another song delivered on the wing, and intended for the 
ear of the mate alone. It is generally heard only after incubation 
has commenced, and is low, but very sweet, and resembles some- 
what the song of a Canary, delivered in an undertone. 
BLUE-WINGED WARBLER. 
HELMINTHOPHILA PINUS. 
Cuar. Above, bright olive; wings and tail dull blue; wings with two 
white bars; tail with several white blotches; black line through the eye ; 
crown and under parts yellow. Length about 5 inches. 
Nest. Ina tuft of grass amid thicket of underbrush or along margin of 
woods; bulky, and loosely made of dried leaves and vegetable fibre, lined 
with fine grass.

About the beginning of May this species enters Pennsylvania 
from the South, and frequents thickets and shrubberies in quest 
of the usual insect food of its tribe. At the approach of win- 
ter, very different from the Pine Warbler, with which it has 
sometimes been confounded, it retires to pass the winter in 
tropical America, having been seen around Vera Cruz in 
autumn by Mr. Bullock. On its arrival it frequents gardens, 
orchards, and willow trees, gleaning among the blossoms, but 
at length withdraws into the silent woods remote, from the
