After having compared numerous specimens of this species from all parts of its range, including Chile, Patagonia, Terra del Fuego, the West India Islands, and all portions of Middle America and the United States, I am unable to appreciate differences according to locality, and cannot recognize any geographical races. As a rule, the specimens from intertropical regions, as might be expected, are the smallest and most brightly colored. The smallest in the series are those from Lower California.
Habits. Probably none of the birds of America have so extended a distribution as this Vulture, occurring, as it does, in greater or less abundance from high northern latitudes at the Saskatchewan, throughout North America from the Atlantic to the Pacific, and in all portions of South America, even to the Straits of Magellan. On the Atlantic coast it is not common north of Central New Jersey, though occasionally individuals have been seen as far north as New Brunswick and Nova Scotia. Several specimens have been taken in various parts of New England, from Calais, Me., to Connecticut. Mr. Lawrence cites it as of rare and irregular occurrence near New York. In one instance he noticed a company of nine individuals at Rockaway, Long Island. West of the Alleghanies it has a much less restricted distribution, from Central America almost to the Arctic regions. It is found more or less frequently in all the Middle, the Southern, Western, and Northwestern States, without an exception. It is met with in large numbers throughout the entire Pacific coast of North America, from Lower California to Washington Territory. Mr. Douglas saw vast numbers of this species in Canada, near Sandwich and Lake St. Clair, during their breeding-season. Dr. Richardson speaks of their having higher summer migrations in the interior of the continent than on the Pacific coast, finding it along the banks of the Saskatchewan, in latitude 55°, late in the month of June. Mr. Say met with them in latitude 59°, and Lewis and Clarke noticed them near the Falls of the Columbia River, in latitude 48°. Mr. Blakiston states that an individual was shot at the Red River Settlement as early as April 27, while the winter’s snow was still covering the ground to the depth of a foot and the rivers were ice-bound. He also observed it at Fort Carlton, in latitude 53°, on the 7th of May, and again, on the 2d of September, in latitude 49°.
Mr. T. H. Jackson, of West Chester, Pa., informs me that this Vulture has been known to breed at Parkersburg, fifteen miles west of the former place, in the summer of 1870, and that they also breed rather plentifully on the banks of the Susquehanna, laying their eggs, two in number, in caves among the rocks, as early as the 10th of April, and that some remain in that vicinity all winter.
Rhinogryphus aura.
Dr. Cooper mentions their great abundance during the summer in all parts of Washington Territory, frequenting the vicinity of prairies and river-banks, but never appearing along the coast. They arrive at Puget Sound about the middle of May, and undoubtedly breed in the Territory. Dr. Suckley met with them at Fort Dalles, in Oregon, and also on Puget Sound. He also met with them not far from Pembina. Dr. Newberry also observed them in California and Oregon, quite common in the vicinity of the towns and about the great rivers. In the Klamath Basin it was more rare, and on the Des Chutes he scarcely saw any; but on the Columbia, especially below the Cascades, they were very plentiful.
Dr. Heermann found this bird ranging over the whole extent of California, meeting them in great numbers in the vicinity of Fort Yuma, at the junction of the Colorado and Gila Rivers.
In the West India Islands these birds occur in Cuba, Jamaica, and Trinidad; but according to Mr. E. C. Taylor, neither this nor any other species of Vulture occurs in any of the islands between Trinidad and St. Thomas, not even in Tobago or Porto Rico. At Trinidad they are very abundant.
Mr. G. C. Taylor found this Vulture common in Honduras, where, however, it does not go much into the towns and villages, but is usually seen on the outskirts and in the forests. In Guatemala, Mr. Salvin found it not nearly so abundant as C. atratus, and there also, as in Honduras, it frequented the more uncultivated and forest districts, leaving to the latter all the duties of the scavenger. Captain C. C. Abbott found this Vulture very common in the Falkland Islands, remaining the whole year round, and breeding.
