GENUS PSEUDOGRYPHUS, RIDGWAY.

Cathartes, AUCT. (in part.)

GEN. CHAR. Size very large, and aspect vulturine. Head much elongated, with regular outlines; the entire head and neck bare of feathers, the skin faintly wrinkled, but free from corrugations or caruncles. Nostril small, occupying only the posterior third, or less, of the nasal orifice, its anterior end acute. Plumage beginning at the bottom of the neck in a ruff of lanceolate, acuminate feathers, these continued over the breast and abdomen. Wings very large, the primaries and secondaries well developed, the former longest, and reaching to, or beyond, the end of the tail; fourth or fifth quill longest; outer five with inner webs appreciably sinuated. Tail even. Sexes alike.

The single species composing this very distinct genus belongs to Western North America, and, so far as known, has the most restricted distribution of any large raptorial bird in the world. It is remarkable for its very large size, all its dimensions nearly, if not quite, equalling those of the famed Condor of the Andes (Sarcorhamphus gryphus).

Localities: Fort Yuma (COUES, Pr. Ac. Nat. Sc. 1866, 42).

HAB. Pacific Coast region from mouth of the Colorado to the Columbia? Southern Utah (HENSHAW).

HABITS. This large Vulture, so far as is known, is restricted to the area on the Pacific Coast from the Columbia River to the Colorado, and extending as far to the east as the Sierra Nevada. None are known to have been taken in Mexico, and it very rarely goes north of the Columbia. It is said to be most common in the hot interior valleys of California, where are large herds of cattle, upon which it, to a large extent, depends for its food. Dr. Cooper saw none on the Colorado, and met with none east of the San Bernardino Mountains. Even at Fort Mohave the cattle killed during the five months he resided there did not attract one of these Vultures.

Dr. Cooper did not see these birds in any number along the sea-coast, and has noticed none on the islands or in the highest Sierra Nevada. Yet they are said, when other food is scarce, to feed on dead seals and whales; but this fact he has never witnessed.

Dr. Newberry states that it was to him a pleasant portion of every day’s experience, in his march through the Sacramento Valley, to watch the graceful evolutions of this Vulture. In its colors the combination was a pleasing one, while its flight was easy and effortless beyond that of any other bird. Though a common bird in California, he found it much more shy and difficult to shoot than its associate, the Turkey-Buzzard; and it was never seen in such numbers or exhibiting such familiarity as the smaller species which swarm, and are such efficient scavengers, in our southern cities. After his party left the Sacramento Valley, he saw very few in the Klamath Basin, and met with none within the limits of Oregon. It is occasionally found there, but much more rarely than in California.

Dr. Newberry states that a fine specimen presented to Dr. Sterling on his return to San Francisco ate freely of the meat given him, and was for some time kept alive. It was, however, impatient of confinement, and succeeded in tearing the cord that confined him from his legs, and in making his escape. Dr. Cooper also saw one of these Vultures in confinement, at Monterey, in the possession of Dr. Canfield. This was a full-grown individual which he had raised from the nest. It had been fed exclusively on fresh meat, had no offensive smell, and was clean and shining. It was gentle and familiar, but seemed stupid, and dozed most of the time on a fence. This was subsequently presented to the Zoölogical Society of London, and formed the subject of our figure. The figure of the young bird on the next page is taken from a photograph of the same specimen at an early age.

Dr. Heermann, in his Report on Lieutenant Williamson’s Survey, mentions having observed this Vulture sailing majestically in wide circles at a great height, and ranging by its powers of flight over an immense space of country in search of food. Often when hunting in the Tejon Valley, if unsuccessful, they would be several hours without seeing one of this species; but as soon as they succeeded in bringing down any large game, these birds would be seen rising above the horizon before the body had grown cold, and slowly sweeping towards them, intent upon their share of the game. In the absence of the hunter, unless well protected, these marauders will be sure to drag out from its concealment the slain animal, even though carefully covered with branches. Dr. Heermann states that he has known them to drag out and devour a deer within an hour. This Vulture possesses immense muscular power. Dr. Heermann has known four of them to drag the body of a young grizzly bear, that weighed over a hundred pounds, the distance of two hundred yards. Dr. Cooper states that it visits the Columbia River in autumn, when its shores are lined with great numbers of dead salmon, on which, in company with other birds and various animals, it feasts for a couple of months. He considered it, however, only a visitor at certain seasons, and not a resident even through the summer. He did not see it, nor did he hear of its presence at Puget Sound.

It is stated by Douglas that these Vultures will in no instance attack any living animal unless it be so severely wounded as to be unable to walk. Their senses of sight and smell are very acute, especially the former; and when searching for prey they soar to a very great height, and if they chance to discover a wounded animal they immediately follow and attack it whenever it sinks down. The first comers are soon followed by others, and it is not long before the carcass is reduced to a skeleton. After thus feeding, they remain for a while sluggish and reluctant to move. At these times they perch on dead trees, with their heads drawn down, and their wings drooping over their feet. Except after feeding, or when protecting their nests, they are said to be very wary, and are with great difficulty shot by the hunter. Their flight is described as slow, steady, and graceful, and they glide along with little or no perceptible motion of the wings, the tips of which are curved upward in flying, in the manner of the Turkey-Buzzard. They are said to appear most numerous and to soar the highest preceding thunder-storms and tempests.

Dr. Townsend states that in their walk they resemble a Turkey strutting over the ground with great dignity, but are clumsy and awkward when they endeavor to hasten their movements. When they attempt to rise from the ground they always hop several yards, in order to give an impetus to their heavy body. Dr. Cooper discredits the statement of Mr. Taylor, that this Vulture has been known to kill and carry off a hare in its claws. These are straight and weak, and not adapted for such uses.

Dr. Heermann states that a nest of this bird with young was discovered in a thicket on the Tuolumne River. It was about eight feet back from the entrance of a crevice in the rocks, completely surrounded and masked by thick underbrush and trees, and composed of a few loose sticks thrown negligently together. He found two other nests, of a like construction and similarly situated, at the head of Merced River and in the mountains. From the latter the Indians were in the habit of yearly robbing the young, to kill at one of their festivals.

Mr. Alexander S. Taylor, of Monterey, published a series of papers in a California journal relative to this Vulture. In one of these he mentions that a Mexican ranchero, in hunting among the highest peaks of the Santa Lucia range, disturbed two pairs of them from their nesting-places, and brought away from one a young bird a few days old, and from the other an egg. There was no nest, the eggs having been laid in the hollow of a tall old robles-oak, in a steep barranca, near the summit of one of the highest peaks. These birds are said by some hunters to make no nest, but simply lay their eggs on the ground at the foot of old trees or on the bare rocks of solitary peaks. Others affirm that they sometimes lay their eggs in old nests of Eagles and Buzzards. Mr. Taylor states that the egg weighed 10.50 ounces, the contents weighing 8.75. The egg was of a dead dull white color, the surface of the shell slightly roughened. It was nearly a perfect ellipse in shape, and measured 4.50 inches in length by 2.38 in diameter. The egg-shell held nine fluid ounces of water. The young Vulture weighed ten ounces. His skin was of an ocreous-yellow, covered with a fine down of a dull white.

Dr. Canfield informed Dr. Cooper that he has seen as many as one hundred and fifty of these birds at one time and place in the vicinity of antelopes he had killed, and noticed that they invariably sighted their prey. They are often killed by feeding on animals that have been poisoned with strychnine. They are not feared by the rancheros, yet Dr. Canfield has known a number to attack a young calf, separate it from its mother, and kill it. A vaquero having killed a large grizzly bear, left it on the plains near the sea-shore, to return to the house, about three miles distant, for assistance. On his return, after an absence of about two hours, a flock of these Vultures had cleaned the entire carcass, leaving only the skin and the skeleton. This Vulture and the Turkey-Buzzard often feed together over the same carcass, and generally do some fighting together. Many of them nest in the high mountains east and south of the Carmelo Valley, and also near Santa Cruz, as well as in the Santa Lucia range, and are found there throughout the year, but in greater numbers from July to November.

An egg of this species, in the collection of the Smithsonian Institution (9,983), from San Rafael, California, obtained by Dr. C. A. Canfield, measures 4.40 inches in length by 2.50 in breadth. It is of an elongate-oval shape, but is decidedly more pointed at the smaller than at the larger end. In color it is of a uniform pale greenish-blue, almost an ashy greenish-white, and without spots.
