CALIFORNIAN VULTURE. [California Condor. ENDANGERED. ] |
Genus | CATHARTES CALIFORNIANUS, Lath.
[Gymnogyps californianus.] |
Of the three species of Vulture which
inhabit the southern parts of North America, this is so much superior in size
to the rest that it bears to them the same proportion as a Golden Eagle to a
Goshawk. It inhabits the valleys and plains of the western slope of the continent,
and has not been observed to the eastward of the Rocky Mountains. Mr. TOWNSEND,
who has had opportunities of observing it, has favoured me with the following
account of its habits.
"The Californian Vulture inhabits the region of the Columbia river, to the
distance of five hundred miles from its mouth, and is most abundant in spring,
at which season it feeds on the dead salmon that are thrown upon the shores in
great numbers. It is also often met with near the Indian villages, being
attracted by the offal of the fish thrown around the habitations. It associates
with Cathartes Aura, but is easily distinguished from that species in flight,
both by its greater size and the more abrupt curvature of its wing. The
Indians, whose observations may generally be depended upon, say that it
ascertains the presence of food solely by its power of vision, thus
corroborating your own remarks on the vulture tribe generally. On the upper
waters of the Columbia the fish intended for winter store are usually deposited
in huts made of the branches of trees interlaced. I have frequently seen the
Ravens attempt to effect a lodgement in these deposits, but have never known the
Vulture to be engaged in this way, although these birds were numerous in the
immediate vicinity."
In a subsequent notice, he continues:--"I have never seen the eggs of the
Californian Vulture. The Indians of the Columbia say that it breeds on the
ground, fixing its nest in swamps under the pine forests, chiefly in the Alpine
country. The Wallammet Mountains, seventy or eighty miles south of the
Columbia, are said to be its favourite places of resort. I have never visited
the mountains at that season, and therefore cannot speak from my own knowledge.
It is seen on the Columbia only in summer, appearing about the first of June,
and retiring, probably to the mountains, about the end of August. It is
particularly attached to the vicinity of cascades and falls, being attracted by
the dead salmon which strew the shores in such places. The salmon, in their
attempts to leap over the obstruction, become exhausted, and are cast up on the
beaches in great numbers. Thither, therefore, resort all the unclean birds of
the country, such as the present species, the Turkey-Buzzard, and the Raven.
The Californian Vulture cannot, however, be called a plentiful species, as even
in the situations mentioned it is rare to see more than two or three at a time,
and these so shy as not to allow an approach to within a hundred yards, unless
by stratagem. Although I have frequently seen this bird I have never heard it
utter any sound. The eggs I have never seen, nor have I had any account of them
that I could depend upon.
"I have never heard of their attacking living animals. Their food while on
the Columbia is fish almost exclusively, as in the neighbourhood of the rapids
and falls it is always in abundance; they also, like other Vultures, feed on
dead animals. I once saw two near Fort Vancouver feeding on the carcass of a
pig that had died. I have not seen them at roost. In walking they resemble a
Turkey, strutting over the ground with great dignity; but this dignity is
occasionally lost sight of, especially when two are striving to reach a dead
fish, which has just been cast on the shore; the stately walk then degenerates
into a clumsy sort of hopping canter, which is any thing but graceful. When
about to rise, they always hop or run for several yards, in order to give an
impetus to their heavy body, in this resembling the Condor of South America,
whose well known habit furnishes the natives with an easy mode of capturing him
by means of a narrow pen, in which a dead carcass has been deposited. If I
should return to the Columbia, I will try this method of taking the Vulture, and
I am satisfied that it would be successful."

The head and upper part of the neck are bare, but the middle of the
forehead to beyond the nostrils, and a semicircular space before the eye, are
closely covered with very small firm feathers; the fore part of the neck is
longitudinally, the occiput and hind neck transversely wrinkled. Plumage full,
compact; feathers of the rut and fore part of the breast lanceolate and
acuminate, of the upper parts ovato-elliptical, broadly rounded, and glossy.
Wings very long, ample, concave; primaries finely acuminate, secondaries
rounded; the first quill two inches and a half shorter than the second, which is
half an inch shorter than the third, the latter exceeded by the fourth by half
an inch, and equal to the fifth. Tail of moderate length, nearly even, of
twelve broad, rounded feathers.
The horny part of the bill yellow; the cere and naked part of the head and
neck yellowish-red. Iris dark hazel. Feet yellowish-grey, claws
brownish-black. The general colour of the plumage is greyish-black, the
feathers of the upper parts narrowly margined with light brown and grey; the
secondaries light grey externally, as are the edges of the primaries; the
margins of the inner secondaries toward the base, and those of the secondary
coverts, with a large portion of the extremity of the latter, are white. The
feathers on the sides under the wing, the axillaries, and many of the lower
wing-coverts, are white.
Length to end of tail 55 inches; bill along the ridge 4 3/4, along the edge
of lower mandible 3 5/12; wing from flexure 34; tail 16; tarsus 4 1/4; hind toe
1 (4 1/2)/12, its claw 1 1/2; second toe 2 1/2, its claw 1 10/12; third toe
4 1/4, its claw 2; fourth toe 2 9/12, its claw 1 4/12.
The young have the horny part of the bill dusky yellowish-grey; the head
and neck covered with dull brown very soft down; the feet greyish-yellow, the
scutella darker, the claws brownish-black. The general colour of the plumage is
blackish-brown, the feathers on the upper part strongly tinged with grey,
especially the secondary quills; the feathers of the back edged with light
brown, the secondary coverts tipped with brownish-white. The feathers on the
sides under the wing, the axillaries, and some of the lower wing-coverts white,
with the centre dusky.
Length to end of tail 48 inches; bill along the ridge 4; wing from flexure
32; tail 16; tarsus 4; middle toe 4, its claw 1 9/12.
