BLACK VULTURE, OR CARRION CROW. [Black Vulture.] |
Genus | CATHARTES ATRATUS, Wilson. [Coragyps atratus.] |
This bird is a constant resident in all
our southern States, extends far up the Mississippi, and continues the whole
year in Kentucky, Indiana, Illinois, and even in the State of Ohio as far as
Cincinnati. Along the Atlantic coast it is, I believe, rarely seen farther east
than Maryland. It seems to give a preference to maritime districts, or the neighbourbood
of water. Although shy in the woods, it is half domesticated in and about our
cities and villages, where it finds food without the necessity of using much
exertion. Charleston, Savannah, New Orleans, Natchez, and other cities, are
amply provided with these birds, which may be seen flying or walking about the
streets the whole day in groups. They also regularly attend the markets and
shambles, to pick up the pieces of flesh thrown away by the butchers, and, when
an opportunity occurs, leap from one bench to another, for the purpose of helping
themselves. Hundreds of them are usually found, at all hours of the day, about
the slaughterhouses, which are their favourite resort. They alight on the roofs
and chimney-tops, wherever these are not guarded by spikes or pieces of glass,
which, however, they frequently are, for the purpose of preventing the contamination
by their ordure of the rain water, which the inhabitants of the southern States
collect in tanks, or cisterns, for domestic use. They follow the carts loaded
with offal or dead animals to the places in the suburbs where these are deposited,
and wait the skinning of a cow or horse, when in a few hours they devour its
flesh, in the company of the dogs, which are also accustomed to frequent such
places. On these occasions they fight with each other, leap about and tug in
all the hurry and confusion imaginable, uttering a harsh sort of hiss or runt,
which may be heard at a distance of several hundred yards. Should eagles make
their appearance at such a juncture, the Carrion Crows retire, and patiently
wait until their betters are satisfied, but they pay little regard to the dogs.
When satiated, they rise together, should the weather be fair mount high in
the air, and perform various evolutions, flying in large circles, alternately
plunging and rising, until they at length move off in a straight direction,
or alight on the dead branches of trees, where they spread out their wings and
tail to the sun or the breeze. In cold and wet weather they assemble round the
chimney-tops, to receive the warmth imparted by the smoke. I never heard of
their disgorging their food on such occasions, that being never done unless
when they are feeding their young, or when suddenly alarmed or caught. In that
case, they throw up the contents of their stomach with wonderful quickness and
power.
The Carrion Crows of Charleston resort at night to a swampy wood across the
Ashley river, about two miles from the city. I visited this roosting place in
company with my friend JOHN BACHMAN, approaching it by a close thicket of
undergrowth, tangled with vines and briars. When nearly under the trees on
which the birds were roosted, we found the ground destitute of vegetation, and
covered with ordure and feathers, mixed with the broken branches of the trees.
The stench was horrible. The trees were completely covered with birds, from the
trunk to the very tips of the branches. They were quite unconcerned; but,
having determined to send them the contents of our guns, and firing at the same
instant, we saw most of them fly off, hissing, grunting, disgorging, and looking
down on their dead companions as if desirous of devouring them. We kept up a
brisk fusilade for several minutes, when they all flew off to a great distance
high in the air; but as we retired, we observed them gradually descending and
settling on the same trees. The piece of ground was about two acres in extent,
and the number of Vultures we estimated at several thousands. During very wet
weather, they not unfrequently remain the whole day on the roost; but when it is
fine, they reach the city every morning by the first glimpse of day.
The flight of this species, although laboured, is powerful and protracted.
Before rising from the ground they are obliged to take several leaps, which they
do in an awkward sidelong manner. Their flight is continued by flappings,
repeated eight or ten times, alternating with sailings of from thirty to fifty
yards. The wings are disposed at right angles to the body, and the feet
protrude beyond the tail, so as to be easily seen. In calm weather they may be
heard passing over you at the height of forty or fifty yards, so great is the
force with which they beat the air. When about to alight, they allow their legs
to dangle beneath, the better to enable them to alight.
They feed on all sorts of flesh, fresh or putrid, whether of quadrupeds or
birds, as well as on fish. I saw a great number of them eating a dead shark
near the wharf at St. Augustine in East Florida; and I observed them many times
devouring young cormorants and herons in the nest, on the keys bordering that
peninsula.
The Carrion Crow and Turkey-Buzzard possess great power of recollection, so
as to recognise at a great distance a person who has shot at them, and even the
horse on which he rides. On several occasions I have observed that they would
fly off at my approach, after I had trapped several, when they took no notice of
other individuals; and they avoided my horse in the pastures, after I had made
use of him to approach and shoot them.
At the commencement of the love season, which is about the beginning of
February, the gesticulation and parade of the males are extremely ludicrous.
They first strut somewhat in the manner of the Turkey Cock, then open their
wings, and, as they approach the female, lower their head, its wrinkled skin
becoming, loosened, so as entirely to cover the bill, and emit a puffing sound,
which is by no means musical. When these actions have been repeated five or six
times, and the conjugal compact sealed, the "happy pair" fly off, and remain
together until their young come abroad. These birds form no nest, and
consequently never breed on trees; the hollow of a prostrate log, or the
excavation of a bank of earth, suffices for them. They never lay more than two
eggs, which are deposited on the bare ground; they are about three inches in
length, rather pointed at the smaller end, thick in the shell, with a pure white
ground, marked towards the greater ends with large irregular dashes of black and
dark brown. Twenty-one days are required for hatching them. The male and
female sit by turns, and feed each other. The young are at first covered with a
light cream-coloured down, and have an extremely uncouth appearance. They are
fed by regurgitation, almost in the same manner as pigeons, and are abundantly
supplied with food. When fledged, which is commonly about the beginning of
June, they follow their parents through the woods. At this period, their head
is covered with feathers to the very mandibles. The plumage of this part
gradually disappears, and the skin becomes wrinkled; but they are not in full
plumage till the second year. During the breeding season, they frequent the
cities less, those remaining at that time being barren birds, of which there
appear to be a good number. I believe that the individuals which are no longer
capable of breeding, spend all their time in and about the cities, and roost on
the roofs and chimneys. They go out, in company with the Turkey-Buzzards, to
the yards of the hospitals and asylums, to feed on the remains of the provisions
cooked there, which are as regularly thrown out to them.
I have represented a pair of Carrion Crows or Black Vultures in full
plumage, engaged with the head of our Common Deer,
the Cervus virginianus.
