"Long
before I discovered this fine Hawk, I was anxious to have an opportunity
of honouring some new species of the feathered tribe with the
name of my excellent friend Dr. RICHARD HARLAN of Philadelphia.
This I might have done sooner, had I not waited until a species
should occur, which in its size and importance should bear some
proportion to my gratitude toward that learned and accomplished
friend.
The Hawks now before you were discovered near St. Francisville,
in Louisiana, during my late sojourn in that State, and had
bred in the neighbourhood of the place where I procured them,
for two seasons, although they had always eluded my search,
until, at last, as I was crossing a large cotton field, one
afternoon, I saw the female represented in the Plate standing
perched on the top of a high belted tree in an erect and commanding
attitude. It looked so like the Black Hawk (Falco niger) of
WILSON, that I apprehended what I had heard respecting it might
prove incorrect. I approached it, however, when, as if it suspected
my evil intentions, it flew off, but after at first sailing
as if with the view of escaping from me, passed over my head,
when I shot at it, and brought it winged to the ground. No sooner
had I inspected its eye, its bill, and particularly its naked
legs, than I felt assured that it was, as has been represented
by those persons who had spoken to me of its exploits, a new
species. I drew it whilst alive; but my intentions of preserving
it and carrying it to England as a present to the Zoological
Society were frustrated by its refusing food. It died in a few
days, when I preserved its skin, which, along with those of
other rare birds, I have since given to the British Museum,
through my friend J. G. CHILDREN, Esq. of that institution.
A few days afterwards I saw the male bird perched on the same
tree, but was unable to approach him so long as I had a gun,
although he frequently allowed me and my wife to pass close
to the foot of the tree when we were on horseback and unarmed.
I followed it in vain for nearly a fortnight, from one field
to another, and from tree to tree, until our physician, Dr.
JOHN B. HEREFORD, knowing my great desire to obtain it, shot
it in the wing with a rifle ball, and sent it alive to me. It
was still wilder than the female, erected the whole of the feathers
of its head, opened its bill, and was ever ready to strike with
its talons at any object brought near it. I made my drawing
of the male also while still alive.
This species, although considerably smaller than the Red-tailed
Hawk, to which it is allied, is superior to it in flight and
daring. Its flight is rapid, greatly protracted, and so powerful
as to enable it to seize its prey with apparent ease, or effect
its escape from its stronger antagonist, the Red-Tail, which
pursues it on all occasions.
The Black Warrior has been seen to pounce on a fowl, kill it
almost instantly, and afterwards drag it along the ground for
several hundred yards, when it would conceal it, and return
to feed upon it in security. It was not observed to fall on
Hares or Squirrels, but at all times evinced a marked preference
for common Poultry, Partridges, and the smaller species of Wild
Duck.
I was told that the young birds appeared to be of a leaden-gray
colour at a distance, but at the approach of winter became as
dark as the parents. None of them were to be seen at the time
when I procured the latter. Of its nest or eggs nothing is yet
known. My friends Messrs. JOHNSON and CARPENTER frequently spoke
of this Hawk to me immediately after my return to Louisiana
from Europe, which took place in November 1829.
