gins anew this curious mode of courtship. The concussion caused, at
the time the bird passes the centre of its plunge, by the new position
of its wings, which are now brought almost instantly to the wind, like
the sails of a ship suddenly thrown aback, is the cause of this singular
noise. The female does not produce this, although she frequently squeaks
whilst on the wing.
Sometimes, when several males are paying their addi'esses to the same female, the sight of those beaux plunging through the air in different directions, is curious and highly entertaining. This play is quickly over, however, for no sooner has the female made her choice, than her approved gives chase to all intruders, drives them beyond his dominions, and re- turns with exultation, plunging and gambolling on the wing, but with less force, and without nearing the ground.
In windy weather, and as the dusk of the evening increases, the Night- Hawk flies lower and more swiftly than ever, making wide and irregular deviations from its general course, to overtake an insect which its keen eye has seen at a distance, after which it continues onward as before. When darkness comes on, it alights either on the ground or on a tree, where it spends the night, now and then uttering its squeak.
These birds can scarcely walk on the ground, on account of the small size and position of their legs, which are placed very far back, for which reason they cannot stand erect, but rest their breast on the ground, or on the branch of a tree, on which they are obliged to alight sidewise. They alight with ease, however, and squat on branches or fence-rails, now and then on the tops of houses or barns. In all such positions they are easily approached. I have neared them when on a fence or low wall to within a few feet, when they would look upon me with their large mild eyes more as a friend than an enemy, although they flew off the moment they ob- served any thing suspicious in my movements. They now and then squeak while thus seated, and when this happens when they are perched on the trees of our cities, they seldom fail to attract the attention of persons passing.
In Louisiana this species is called by the French Creoles "Cropped volant," in Virginia "Bat," but the name by which it is most commonly known is "Night-Hawk." The beauty and rapidity of its motions render it a tempting object to sportsmen generally, and its flesh is by no means unpalatable. Thousands are shot on their return to the south during the autumn, when they are fat and juicy. Now and then at this
