Obs. The King Vulture is the most handsome bird of its family. Though admitted by Nuttall as a bird of the United States (Manuel, I. p. 40, Boston, 1840,) no instance is recorded, or has otherwise come to our knowledge, of its having been observed north of Mexico. It is not improbable, however, that it may yet be found in Texas or in California, or possibly in Florida. It is described by Hernandez as an inhabitant of Mexico, in his “New History of the Plants, Animals, and Minerals of Mexico,” p. 319, (Nova, plantarum, animalium et mineralium Mexicanorum, Historia, Rome, 1651, folio,) and has found a place in the works of all authors on general Ornithology, and been noticed by many travellers. The above comprise all the Vultures which have been hitherto known or supposed to inhabit America, north of Mexico. There are three other species which appear to be peculiar to South America and the islands of West Indies, (particularly the more southern of them,) all of which more or less intimately resemble our species of the North. They are _Cathartes jota_ (Molina), described in Geog. Nat. and Civil Hist. of Chili, American edition, I. p. 185, (Middletown Conn. 1808, octavo,) _Cathartes Brasiliensis_, Bonaparte Consp. Av. p. 9, and _Cathartes urbicola_, Des Murs Rev. and Mag. de Zool. April, 1853. The latter is a large and very remarkable species which has only recently been ascertained to frequent the cities of several of the West Indies. Nearly all of the American Vultures are remarkable for a disposition manifested, in a greater or less degree, to resort to cities, or even more isolated abodes of men, for the purpose of procuring food. In the southern cities of the United States, the Black Vulture congregates in large numbers; its relative of South America (_Cathartes Brasiliensis_) possesses the same habit, and is exceedingly abundant in the cities of the countries that it inhabits. Even the gigantic Condor does not hesitate to make its appearance in the vicinity of villages or dwellings in the western countries of South America for the same purpose. In this respect these birds resemble the most common European bird of their family which inhabits southern Europe, and also Asia and northern Africa; the _Neophron percnopterus_ or Egyptian Vulture. The latter is, however, very different in colour, being nearly white when adult, and _clean_, which is an important consideration in a bird of habitually filthy habits.
