A History of North American Birds, Land Birds. Volume 3

Mr. E. C. Taylor, in his paper on the Birds of the West Indies, mentions the great abundance of Black Vultures at Port of Spain, in Trinidad. They swarmed over the town, covered the roofs of the houses, and lived on the best terms with the poultry. So tame and familiar were they that he often poked them with his stick or umbrella as he walked through the streets. At night they roosted in the trees in the gardens and squares of the town. They were very abundant all over Trinidad and in the parts of Venezuela he visited, but he found none in any of the islands from Trinidad to St. Thomas. This species was not found in Jamaica by Mr. Gosse, but Mr. March afterwards reported it as a “recent settler.”

Catharista atrata.

Mr. G. C. Taylor (Ibis, 1860, p. 22) found the Black Vulture very abundant in Honduras, where it is always to be seen in the villages, sitting on the roofs of the houses, wheeling in flocks high in the air, or feeding on the offal in the streets. They were very tame and very numerous, forty or fifty being frequently seen in a single company. They abounded in all parts of Central America that he visited.

With the exception of Quiscalus macrurus, Mr. Salvin regards this species as the most familiar bird in Guatemala. At night they retired to the forests, and in the early morning trooped back to their posts in the streets and lanes, and about the tops of the houses and churches. They generally nested in the forests, though in Antigua Guatemala they were said to use the ruins of the old churches for that purpose.

Mr. Dresser found this Vulture about equally common with the R. aura on the Lower Rio Grande, but much less common near San Antonio. He usually found the two species in company, attended also by the Polyborus auduboni and Craxirex harrisi. They were found breeding among the rocks at Systerdale, where they were said to be the only species found.

Dr. Coues did not meet with any in Arizona, nor were any taken on the survey of the Mexican boundary. In South Carolina he considered it chiefly confined to the lower country, while the C. aura is more generally distributed over the State. The two meet together freely, and as they circle about in each other’s company they afford an excellent opportunity of noticing the great differences in their mode of flight and in the outline of their bodies and wings. On the other hand, Wilson, Ord, and others deny that the two kinds live together.

In the Southern Atlantic cities, especially Charleston and Savannah, the Black Vulture is a semi-domestic bird, and is very abundant. It is also to be found in the interior, but is neither so common nor so tame.

The Catharista atratus is said to be much more sensitive to cold than the aura, and when the weather is at all unfavorable they cower around the tops of chimneys to enjoy the heat. Though tolerated and even protected by law, their filthy habits render them a source of annoyance to those whose houses they frequent. Their value as scavengers and the services they render in the removal of offal render them almost a necessity in Southern cities.

Both in their mode of flight and in their movements upon the ground this species differs materially from the Turkey-Buzzard. The latter walks steadily while on the ground, and when it mounts does so by a single upward spring. The Black Vulture is ill at ease on the ground, moves awkwardly, and when it essays to fly upward takes several leaps in a shuffling sidelong manner before it can rise. Their flight is more labored, and is continued by flapping several times, alternating with sailing a limited distance. Their wings are held at right angles, and their feet protrude beyond their tail-feathers. In all these respects the differences between the two birds are very noticeable, and plainly mark the species.

Mr. Audubon states that at the commencement of the mating-season, early in February, the gesticulations of the males are very conspicuous. They strut in the manner of a Turkey-cock, open their wings, lower their heads, and utter a puffing sound that is anything but musical.

Alexander Wilson describes with great minuteness a scene he witnessed near Charleston, where the carcass of a horse was devoured by these birds, the ground for hundreds of yards around being black with them. He counted at one time two hundred and thirty-seven, while others were in the air flying around. He ventured within a few yards of the horse without their heeding his presence. They frequently attacked one another, fighting with their claws and striking with their open wings, fixing their claws in each other’s head. They made a hissing sound with open mouths, resembling that produced by thrusting a red-hot poker into water, and occasionally a snuffling noise, as if clearing their nostrils. At times one would emerge with a large fragment, and in a moment would be surrounded by several others, who would tear it in pieces and soon cause it to disappear.

The Black Vulture breeds on or near the ground in the same manner as the Turkey-Buzzard, in hollow logs, decayed trunks of trees, and stumps, and also without this protection, the bare earth only being made use of. It is said to make no nest. The eggs seldom, if ever, exceed two in number. These are greater, both in their length and capacity, than those of the Turkey-Buzzard, although the measurements of the birds themselves would seem to show the latter to be apparently the larger bird. The average weight of the Black Vulture’s egg, however, is about one pound, or fifteen per cent greater than that of the Buzzard. Three from Charleston, Galveston, and the Rio Grande furnish the following measurements: 3.81 inches by 1.94; 3 by 2.06; 3.06 by 1.94. The principal difference between the eggs of this and the preceding species is in regard to their size. Their ground-color is the same, or nearly the same,—a yellowish-white or cream-color, almost never a pure white, and only in exceptional cases. The eggs are more elongate in their shape, and the blotches are usually larger. These are of a dark reddish-brown, confluent, and chiefly distributed around the larger end. There are also markings, smaller and less frequent, of lilac and purplish-drab, similar to those noticed in the eggs of C. aura. An egg from the Rio Grande is marked with small spots of reddish-brown and obscure lilac, equally distributed over the whole surface on a ground of cream-color.

Mr. Audubon is positive that this Vulture never breeds in trees, and that they never build any nest, but deposit their eggs on the ground, on a dead log, or in a hollow tree. Twenty-one days are required for hatching their eggs, on which the male and female sit by turns and feed each other. The young are covered with a light cream-colored down, and are fed with regurgitated food, in the manner of Pigeons. As soon as they are able, they follow their parents through the woods, at which period their entire head and neck, which afterwards become bare, are covered with feathers.

Family COLUMBIDÆ.—The Pigeons

Char. The basal portion of the bill covered by a soft skin, in which are situated the nostrils, overhung by an incumbent fleshy valve, the apical portion hard and convex. The hind toe on the same level with the rest; the anterior toes without membrane at the base. Tarsi more or less naked; covered laterally and behind with hexagonal scales.

The bill of the Columbidæ is always shorter than the head, thinnest in the middle; the basal half covered by a soft skin; the apical portion of both jaws hard; the upper one very convex, blunt, and broad at the tip, where it is also somewhat decurved. There is a long nasal groove, the posterior portion occupied by a cartilaginous scale, covered by a soft cere-like skin. The nostrils constitute an elongated slit in the lower border of the scale. The culmen is always depressed and convex. The bill is never notched in the true Doves, though Didunculus shows well-defined serrations. The tongue is small, soft, and somewhat fleshy.

The wing has ten primaries, and eleven or twelve, rarely fifteen, secondaries; the latter broad, truncate, and of nearly equal length. The tail is rounded or cuneate, never forked.

The tarsus is usually short, rarely longer than the middle toe, scutellate anteriorly, and with hexagonal plates laterally and behind; sometimes naked. An inter-digital membrane is either wanting entirely, or else is very slightly indicated between the middle and outer toes.

The valuable monograph of Bonaparte in the second part of Conspectus Avium renders the task of arranging the American Columbidæ in proper sequence and of determining their synonomy comparatively easy. He divides the family into Lopholæminæ, Columbinæ, Turturinæ, Zenaidinæ, and Phapinæ, the second and fourth alone occurring in North America. They may be briefly distinguished as follows:—

Columbinæ. Tarsus shorter than the lateral toe; feathered above.

Zenaidinæ. Tarsus longer than the lateral toes; entirely bare of feathers.

Subfamily COLUMBINÆ

Char. Tarsi stout, short, with transverse scutellæ anteriorly; feathered for the basal third above, but not at all behind. Toes lengthened, the lateral decidedly longer than the tarsus. Wings lengthened and pointed. Size large. Tail-feathers twelve.

This section of doves embraces the largest North American species, and among them the more arboreal ones. The genera are as follows:—

Columba. Head large; tail short, broad, and rounded.

Outer toe much longer than the inner; bill rather short, stout … Columba.

Outer toe scarcely longer than the inner; bill lengthened, compressed … Patagiœnas.

Ectopistes. Head very small; tail much lengthened, cuneate.

Genus COLUMBA, Linnæus

Columba, Linnæus, Syst. Nat. 1735. (Type, Columba livia, L.)

Gen. Char. Bill stout and rather short; culmen from the base of the feathers about two fifths the head. Lateral toes and claws about equal, reaching nearly to the base of the middle claw; the claws rather long, and not much curved. Tail rather short, rounded, or nearly even; as long as from the carpal joint to the end of secondaries in the closed wing. Second and third quills longest.

Columba fasciata.

The genus Columba, as characterized above, includes the C. livia, or domestic Pigeon, the differences between it and the American forms being very slight. Reichenbach and Bonaparte separate the North American birds from Columba, under the name of Chlorœnas, while C. leucocephala and a near ally of the West Indies (C. corensis) have been placed in the subgenus Patagiœnas, Reichenbach.

The variations of form among the numerous American members of Columba are more with the species, however, than with groups, and withal are so exceedingly slight that an attempt at subdividing the genus is scarcely justifiable. They may be arranged by the style of coloration as follows. None of the American species have the forepart of the neck metallic, as in the European species, or Columba proper, as restricted, and in which these metallic feathers have the fibres loose and blended, instead of being compact; the feathers also have a well-defined squamate arrangement in nearly or quite all the American Columbæ.

Sp. Char. Above ash, inclining to olivaceous on the back, and with a fine bluish cast on the rump, under surface of wings, and sides. The primaries and basal portion of the tail dusky. Larger wing-coverts and secondaries, with primaries, distinctly edged with white; terminal third of tail of nearly the same tint as the wing-coverts, but the basal portion much darker, with a rather indistinct, narrow dusky band between the two shades, a little beyond the tips of the upper coverts. Whole head, lateral and front part of neck, and lower parts to the anal region, ashy vinaceous-purple, lighter, and more pinkish on the abdomen; chin considerably lighter; anal region and crissum white. A narrow half-collar of white across the upper portion of the nape; feathers beneath this dull metallic golden-green, with an occasional bronzy reflection, the feathers somewhat squamate. Bill and feet yellow, the former black at the end; iris red. Length, about 15.00; wing, 8.80; tail, 6.10. Female smaller, and less deeply colored, the purplish tint more ashy; sometimes with the nuchal white band obsolete or wanting; the abdomen whitish, etc.

Hab. Pacific Province of United States, and table-lands of Mexico, to Guatemala. Oaxaca (Scl. 1858, 304); Xalapa, 1859, 369 (Cordova, 1856, 359); Guatemala (Salvin, Ibis, II, 276); Fort Whipple, Arizona (Coues, P. A. N. S. 1866, 93); Vera Cruz, alpine region (Sum. M. Bost. Soc. I, 562).

Columba fasciata.

Specimens—even those from the same locality—vary a great deal in size, particularly as to the bill, and there is also considerable variation in the shade and depth as well as the extent of the purplish tint; this varies from a purplish-chocolate tint to nearly violaceous, and sometimes tinges the ends of the lower tail-coverts; sometimes the back has faint bronzy reflections. Guatemalan skins have the white edgings to the wing-coverts less conspicuous than in northern ones, showing an approximation to the features of var. albilinea of Costa Rica; they also have a shorter bill than California specimens. Oregon birds, on the other hand, have longer bills than the California, and are considerably darker in color.

Habits. The Band-tailed Pigeon was first met with in Long’s expedition to the Rocky Mountains, and described by Say in 1823. It is found from the northern Rocky Mountains westward to the Pacific, and from Central America northward along the whole of the Pacific Coast as far to the north as Washington Territory, and probably portions of British Columbia.

Mr. Townsend, quoted by Audubon, noticed this Pigeon from the eastern spurs of the Rocky Mountains across to the Columbia River, where it was very abundant. He noticed their arrival in very great numbers on the 17th of April, and they continued in large flocks even while breeding. Their breeding-places were on the banks of the river, the eggs were placed on the ground, under small bushes without any nest, where numbers congregated together. The eggs were two in number, and are described as of a yellowish-white color, some inclining to a bluish-white with minute white dots at the larger end.

These birds feed on the berries of the black-elder and the buds of the balsam poplar. When sitting on the trees, they huddle close together in the manner of the Carolina Parrot, and many may be killed at a single discharge. Their flesh is said to be tender, juicy, and fine eating.
