The flight of the Warbling Flycatcher is performed by gentle glid-
ings, 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 tliatit raises more than one larood each season, although I have observed it as late as the 1 5th 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 Flycatchers were frequently heard in full sonff.
