DESCRIPTION AND TECHNICAL OBSERVATIONS.

Genus Culicivora. Swainson, Zoological Journal, III., p. 359. (1827.)

Small, bill rather long, compressed towards the tip, wider at base, upper mandible somewhat curved, base with about five pairs of rather long, weak bristles; wing, moderate or rather short, first quill very short, fourth and fifth, longest and nearly equal; tail, long, with the feathers graduated, outer shortest; legs, long, slender; toes, rather short. Colors usually cinereous and black. A genus exclusively American and containing several species.

Culicivora Mexicana. Bonap. Cons. Av., p. 316. (1850.)

Form. Small and slender; bill, moderate, rather long; wings, moderate; tail, long, several of the central feathers equal, others shorter and graduated, outer feathers shortest; legs and feet, long and slender.

Dimensions. Total length (of skin) about 4¼ inches; wing, 12¾; tail, 2¼; inches.

Colors. Male.—Head, above, glossy black; upper parts of the body and wings, grayish-cinereous or lead-colored; lower parts very pale ashy-white, deeper on the sides and flanks; quills, brownish-black, edged externally with ashy-white; tail, black, the two outer feathers tipped with white, having their outer webs of that color, the next two also edged on their outer webs with white and tipped with the same, readily seen on the inferior surface of the tail; bill and legs, dark. Female, with the head above uniform with the other parts—not black—otherwise, like the male.

Hab. Texas, Mexico. Spec. in Mus. Acad., Philada., and Nat. Mus., Washington city.

Obs. This species very much resembles the South American Culicivora leucogastra, De Wied, (which is C. atricapilla, Swainson,) but is smaller. We have never seen specimens of the present species with the under parts of such a clear white as is usual in the larger bird just mentioned, though it may assume it in its perfectly mature plumage. The South American bird measures in total length about five inches.

The Prince of Canino’s description of Culicivora mexicana as cited above, we regard as applicable to the female of the present species. All the species of this genus more or less resemble each other, and now require careful revision, having the appearance to us of being rather confused than otherwise, and but imperfectly described.

PLATE XXVIII.—Adult Male.

We have the pleasure of presenting to the reader, in the plate now before him, one of the most singular of the birds of the family of Crows and Jays yet known to inhabit North America.

This bird was discovered in the Rocky Mountains, by that learned and enthusiastic naturalist, Maximilian, Prince of Wied, who in the course of travels in North America, and especially in the interior, contributed a large amount of valuable information relating to the natural history of the northern portion of our continent, as he had previously to that of South America. Few books, in fact, contain more important observations in the various departments of North American Zoology than the work of that nobleman, “Travels in the Interior of North America,—edition in German, Coblenz, 1839;” but, unfortunately, and certainly without his approbation, nearly everything relating to natural history is omitted in the English edition, London, 1843. In Ornithology, the works of the Prince Maximilian are particularly valuable, and in that relating to North America, there are many notices of little known and interesting species, and the first descriptions of some which have since been regarded as previously unknown by American writers.

The present bird differs in generic as well as specific characters from all other forms of the family to which it belongs. Its short, heavy figure approximates it somewhat to the Nut-crackers of the old world (Nucifraga), and to Clark’s Crow of Western America (Picicorvus columbianus), and its habits, so far as known, are in some respects similar to those of the latter. It does not appear, however, to be in any considerable degree a fruit-eater, but is decidedly carnivorous, and almost rapacious; preying on Reptiles, particularly the various species of Phrynosoma, or Horned Frogs, as they are called with but little propriety, which abound in Western North America. It appears, in fact, to resemble in habits, to some extent, the reptile-eating Kingfishers (Genus Todiramphus) of Asia, the Pacific islands and Australia, and if not absolutely allied, is certainly a strongly analogous representative of those curious birds.

The first specimens of this bird which were brought to the attention of American naturalists, were sent to the Philadelphia Academy, by Mr. Edward M. Kern, who procured them during his connection with Col. Frémont’s Expedition of 1846; and previously no others appear to have reached Europe, than those of its discoverer, the Prince Maximilian.

More recently it has been observed by several of the naturalists who have visited Western America. Our friend, T. Charlton Henry, M. D., of the United States’ Army, has noticed it repeatedly in the vicinity of Fort Webster, in New Mexico. To him we have the pleasure of expressing our obligations for the following interesting notes relating to this bird, as well as for many others:

“This singular and handsome Jay, I first met with near San Miguel, in July, 1852, where I observed a party of some twenty or thirty specimens flitting through the cedars along the roadside. They were mostly young birds, and constantly alighted on the ground, for the purpose, as I ascertained, of capturing lizards, which they killed with great readiness and devoured.

“Since that time, I have frequently observed this bird in the winter only, in the neighborhood of Fort Webster, and always in flocks of about forty or fifty; indeed I am not sure that I have not repeatedly fallen in with the same flock, and it may not therefore be as abundant as I am inclined to suppose. Here they evince an exceeding wariness and are very difficult to approach; I have chased a flock for hours without succeeding in getting within gun-shot.

“Almost invariably a flock alights near the summit of a hill, and passes down its side rapidly, all the birds keeping quite near to each other, and individuals frequently alighting on the ground, when their attention is attracted by their favorite food. They appear to be very social and keep up a continued twittering note. I have occasionally seen them flying in close flocks, high in the air, and apparently passing from one mountain or hill to another.

“This bird, so far as I have seen, is exclusively a mountain species, as I have never observed it in the plains or the bottom lands, which are the usual haunts of its relatives, Steller’s and the California Jay. It differs, however, from them in many respects, and is the only species of these birds that I have never met with singly or in parties of half-a-dozen individuals only. I have always seen it in large flocks. Its food appears to be exclusively reptiles.”

C. B. R. Kennerly, M. D., a young naturalist of great promise, who was attached as Zoologist to Lieut. Whipple’s party, for surveying a route for a railroad to the Pacific Ocean, brought fine specimens of the bird now before us, in the large and highly interesting collection of birds made by him in the countries traversed by the expedition. To Dr. Kennerly we are indebted for the following notice of this species:

“During the march of our party from the Rio Grande to the Sierra Madre, we saw this bird nearly every day. At that season, which was November, large flocks were constantly found in the vicinity of the running streams, which on being frightened from the low bushes, circled around, loudly uttering their peculiar cry, and rising higher and higher, until they reached the summit of some tree on the rocky hills. When settled, they continued their discordant notes, which somewhat resemble some of those of the common Cat-bird (Mimus felivox).”

The Prince Maximilian’s specimens of this bird were obtained on Maria’s river, one of the tributaries of the Upper Missouri, in the northern part of the possessions of the United States in Western America, and much farther north than it has been observed by either of the late naturalists. It probably inhabits a very extensive district, the limits of which cannot at present be conjectured.

The figure in the present plate is that of the adult male, and is about two-thirds of the natural size.
