246 SINGING BIRDS. 



States, and after staying to feed for a week or ten days, it 

 proceeds to its northern breeding-place in the wilds of Canada, 

 of which we are wholly ignorant. In November I have ob- 

 served a few on their return to the South, and according to 

 Vieillot, they winter in St. Domingo and other of the larger 

 West India islands. 



Near Farranville, on the Susquehanna, within the range of 

 the Alleghany Mountains, in the month of May, I saw and 

 heard several pairs of this rare species in the shady hemlock- 

 trees. The males were uttering their slender, wiry, and very 

 peculiar notes, while busily engaged in foraging for insects, 

 and seemed, by being paired, to prepare for incubation. 



The Pine Swamp Warbler {Sylvia sphagnosa) is now consid- 

 ered only as the young of this species, of which, however, I 

 think there yet remains some doubt. 



The history of this species need no longer remain a mystery, for 

 while not abundant, its nesting habits may be studied in any suita- 

 ble locality in New England or northern New York, or along the 

 higher altitudes of the AUeghanies as far down as Georgia ; though 

 the major portion of the flocks pass on to the Canadian faunalarea 

 before stopping to build. 



I did not meet with many examples in New Brunswick, and Mr. 

 Neilson thinks it rare near Quebec city; but Mr. Wintle calls it 

 common near Montreal, and the Ontario observers also regard it 

 as common. It winters in Florida as well as in the West Indies.
