THE WARBLING VIREO. 
ly, indeed furiously, and although I did not see them strike it, compelled it 
to leave the place. 
The flight of the Warbling Vireo is performed by gentle glidings, and 
seldom extends to a greater length than a hundred yards at a time. I never 
saw it on the ground. 
It was never observed by me in Louisiana or Kentucky, nor does it pass 
along the maritime districts of Georgia or the Carolinas ; but from Virginia 
to Maine it is not uncommon, although I saw none farther north. It arrives 
in the Jerseys and Pennsylvania about the first of May, some years perhaps 
a little earlier, and proceeds farther east as the season advances. I do not 
think that it raises more than one brood each season, although I have 
observed it as late as the 15th of October in the Middle Districts, where I 
believe the greater number of these birds spend the summer. Not one 
could I see during the winter in the Floridas, where, however, the White- 
eyed and Red-eyed Vireos were frequently heard in full song. 
It is very surprising that this species, which is found on the Columbia 
river, and in our Middle and Eastern Districts, enters, traverses, and leaves 
the United States in a manner unknown to any one. When on my way to 
the Texas, I met with most of our small birds, but with none of this species.

The swamp magnolia is abundant in all marshy places from Louisiana to 
Connecticut, growing in groves in and around the swamps. It seldom 
exceeds twenty feet in height, and is more usually eight or ten. The flowers
