THE WHITE-EYED FLY-CATCHER, OR VIREO.
Vireo noveboracensis, Ch. Bonap.
PLATE LXIII. Male.
This interesting little bird enters the State of Louisiana often as early as the 1st of March. Indeed, some individuals may now and then be seen a week or ten days sooner, provided the weather be mild. It throws itself into the thickest part of the briars, sumachs, and small evergreen bushes,, which form detached groves in abandoned fields, where its presence is at once known by the smartness of its song. This song is composed of many different notes, emitted with great spirit, and a certain degree of pomposity, which makes it differ materially from that of all other Fly-catchers. It is frequently repeated during the day.
These birds become at once so abundant, that it would be more difficult not to meet one, than to observe a dozen or more, during a morning walk. Their motions are as animated as their music. They pass from twig to twig, upwards or downwards, examining every opening bud and leaf, and securing an insect or a larva at every leap. Their flight is short, light, and easy. Their migrations are performed during the day, and by passing from one low bush to another, for these birds seldom ascend to the tops of even moderately tall trees. Like all our other visitors, they move eastward as the season opens, and do not reach the Middle States before the end of April, or the beginning of May. Notwithstanding this apparently slow progress, they reach and disperse over a vast expanse of country. I have met with some in every part of the United States which I have visited.
Many remain in Louisiana, where they rear two broods, perhaps sometimes three, in a season. Of this, however, I am not quite certain. I never saw them alight on the ground, unless for the purpose of drinking, or of procuring fibrous roots for their nests. They are fond of sipping the dew drops that hang at the extremities of leaves. Their sorties after insects seldom extend beyond the bushes.
About the first of April, the White-eyed Fly-catcher forms a nest of dry slender twigs, broken pieces of grasses, and portions of old hornets'
