THE NIGHT-HAWK. [Common Nighthawk.] |
Genus | CHORDEILES VIRGINIANUS, Briss. [Chordeiles minor.] |
The name of this bird disagrees with the most marked characteristics of its
habits, for it may be seen, and has frequently been seen, on the wing, during
the greater part of the day, even when the atmosphere is perfectly pure and
clear, and while the sun is shining in all its glory. It is equally known that
the Night-Hawk retires to rest shortly after dusk, at the very time when the
loud notes of the Whip-poor-will, or those of the Chuck-will's-widow, both of
which are nocturnal ramblers, are heard echoing from the places to which these
birds resort.
About the 1st of April, the Night-Hawk makes its appearance in the lower
parts of Louisiana, on its way eastward. None of them breed in that State, or
in that of Mississippi, nor am I inclined to believe any where south of the
neighbourhood of Charleston, in South Carolina. The species is, however, seen
in all the Southern States, on its passage to and from those of the east. The
Night-Hawks pass with so much comparative swiftness over Louisiana in the
spring, that in a few days after their first appearance none are to be seen; nor
are any to be found there until their return in autumn, when, on account of the
ample supply of food they still meet with at this late season, they remain
several weeks, gleaning the insects off the cotton fields, waste lands, or sugar
plantations, and gambolling over the prairies, lakes or rivers, from morning
till night. Their return from the Middle Districts varies according to the
temperature of the season, from the 15th of August to late in October.
Their migrations are carried on over so great an extent, and that so
loosely, that you might conceive it their desire to glean the whole country, as
they advance with a front extending from the mouths of the Mississippi to the
Rocky Mountains, passing in this manner from the south far beyond our eastern
boundary lines. Thus they are enabled to disperse and breed throughout the
whole Western and Eastern States, from South Carolina to Maine. On their way
they may be seen passing over our cities and villages, alighting on the trees
that embellish our streets, and even on chimney tops, from which they are heard
to squeak their sharp notes, to the amusement or surprise of those who observe
them.
I have seen this species in the British Provinces of New Brunswick and Nova
Scotia, where they remain so late as the beginning of October, but I observed
none in Newfoundland, or oil the shores of Labrador. In going north, their
appearance in the Middle States is about the first of May; but they seldom reach
Maine before June.
The Night-Hawk has a firm, light, and greatly prolonged flight. In dull
cloudy weather, it may be seen on the wing during the whole day, and is more
clamorous than at any other time. The motions of its wings while flying are
peculiarly graceful, and the playfulness which it evinces renders its flight
quite interesting. The bird appears to glide through the air with all
imaginable ease, assisting its ascent, or supporting itself on high, by
irregular hurried flappings performed at intervals, as if it had unexpectedly
fallen in with its prey, pursued, and seized it. Its onward motion is then
continued. It moves in this manner, either upwards in circles, emitting a loud
sharp squeak at the beginning of each sudden start it takes, or straight
downwards, then to the right or left, whether high or low, as it presses onward,
now skimming closely over the rivers, lakes, or shores of the Atlantic, and
again wending its way over the forests or mountain tops. During the love season
its mode of flight is particularly interesting: the male may be said to court
his mate entirely on the wing, strutting as it were through the air, and
performing a variety of evolutions with the greatest ease and elegance, insomuch
that no bird with which I am acquainted can rival it in this respect.
It frequently raises itself a hundred yards, sometimes much more, and
apparently in the same careless manner already mentioned, its squeaking notes
becoming louder and more frequent the higher it ascends; when, checking its
course, it at once glides obliquely downwards, with wings and tail half closed,
and with such rapidity that a person might easily conceive it to be about to
dash itself against the ground. But when close to the earth, often at no
greater distance than a few feet, it instantaneously stretches out its wings, so
as to be nearly directed downwards at right angles with the body, expands its
tail, and thus suddenly checks its downward career. It then brushes, as it
were, through the air, with inconceivable force, in a semicircular line of a few
yards in extent. This is the moment when the singular noise produced by this
bird is heard, for the next instant it rises in an almost perpendicular course,
and soon begins 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 addresses 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 returns 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 mc with their large mild eyes more as a friend than an enemy, although
they flew off the moment they observed any thing suspicious in my movements.
They now and then squeak while thus seated, and if 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 "Crapaud 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 season, they plunge through the air, but
the rustling sound of their wings at this or any other time after the love
season is less remarkable.
In the Middle States, about the 20th of May, the Night-Hawk, without much
care as to situation, deposits its two, almost oval, freckled eggs on the bare
ground, or on an elevated spot in the ploughed fields, or even on the naked
rock, sometimes in barren or open places in the skirts of the woods, never
entering their depths. No nest is ever constructed, nor is the least
preparation made by scooping the ground. They never, I believe, raise more than
one brood in a season. The young are for some time covered with a soft down,
the colour of which, being a dusky-brown, greatly contributes to their safety.
Should the female be disturbed during incubation, she makes her escape,
pretending lameness, fluttering and trembling, until she feels assured that you
have lost sight of her eggs or young, after which she flies off, and does not
return until you have withdrawn, but she will suffer you to approach her, if
unseen, until within a foot or two of her eggs. During incubation, the male and
female sit alternately. After the young are tolerably grown, and require less
warmth from their parents, the latter are generally found in their immediate
neighbourhood, quietly squatted on some fence, rail, or tree, where they remain
so very silent and motionless that it is no easy matter to discover them.
When wounded they scramble off very awkwardly, and if taken in the hand
immediately open their mouth to its full extent repeatedly, as if the mandibles
moved on hinges worked by a spring. They also strike with their wings in the
manner of pigeons, but without any effect.
The food of the Night-Hawk consists entirely of insects, especially those
of the Coleopterous order, although they also seize on moths and caterpillars,
and are very expert at catching crickets and grasshoppers, with which they
sometimes gore themselves, as they fly low over the ground with great rapidity.
They now and then drink whilst flying closely over the water, in the manner of
swallows.
None of these birds remain during the winter in any portion of the United
States. The Chuck-will's-widow alone have I heard, and found far up the St.
John's river, in East Florida, in January. Frequently during autumn, at New
Orleans, I have known some of these birds to remain searching for food over the
meadows and river until the rainy season had begun, and then is the time at
which the sportsmen shoot many of them down; but the very next day, if the
weather was still drizzly, scarcely one could be seen there. When returning
from the northern districts at a late period of the year, they pass close over
the woods, and with so much rapidity, that you can obtain only a single glimpse
of them.
While at Indian Key, on the coast of Florida, I saw a pair of these birds
killed by lightning, while they were on wing, during a tremendous thunderstorm.
They fell on the sea, and after picking them up I examined them carefully, but
failed to discover the least appearance of injury on the feathers or in the
internal parts.
