Part 31

Crotophaga Ani.—+Linn.+

Pl. Enl. 102.

Length 14³⁄₄ inches, expanse 17³⁄₄, flexure 6¹⁄₄, tail 7³⁄₄, rictus 1³⁄₁₀, height of beak ⁹⁄₁₀, tarsus 1⁸⁄₁₀, middle toe 1⁹⁄₁₀.

Irides deep hazel, feet black; beak black, the ridge semitransparent, furrowed perpendicularly. Plumage black, with rich purple reflections, most conspicuous on the wing-quills; the clothing feathers have the disk of an intense black, with a lighter border, brilliantly iridescent; the borders on the neck are larger in proportion, and are sometimes brassy.

Intestine 12 inches; two cæca, 1¹⁄₂ inch long, 2 inches from the cloaca.

The young have not the scaly character of the plumage, nor any ridge upon the beak.

In all open places, but particularly savannas and pastures which are occupied by cattle or horses, these birds are seen all day long, and all the year round. They are perhaps the most common of the birds of Jamaica. Familiar and impudent, though very wary, they permit a considerable acquaintance with their manners, while an approach within a limited distance, in a moment sets the whole flock upon the wing, with a singular cry, which the negroes please to express by the words, going-awa-a-ay, but which may be as well described, according to the fancy of the hearer, as How-d’ye? or Anī. The appearance of the bird in its gliding flights is unusual; the body is slender, the head large, and the beak enormous; and as in flying it assumes a perfectly straight form, with the long tail in the same line, without flapping the wings, it takes the aspect, on a side view, rather of a fish than of a bird. The centre of the upper mandible is hollow, and the surrounding part is composed of cells of very thin bone, as is the lower mandible. It thus bears a great resemblance to the beaks of the Toucans and Hornbills. The belly is thin and lank, and the bird, even though fat, has always the appearance of meagreness: the shabbiness of the downy feathers that clothe the belly and the long tibiæ, adds to this effect. In these particulars, as well as in general aspect and manners, the Blackbird displays a strong affinity to the Cuckoos and Toucans; indeed, if I may judge from a living Rhamphastos carinatus which was some time in my possession, it seems nearer to the latter than to the former.

The food of our Blackbird, though consisting mainly of insects, is not confined to them. We usually find the stomach distended with caterpillars, moths, grasshoppers, beetles, and other insects, to such a degree that we wonder how the mass could have been forced in. But I have found these contents mixed up with, and stained by the berries of the snake-withe; and in July I have found the stomach crammed with the berries of the fiddle-wood, (Cytharaxylon,) which had stained the whole inner surface of a bright crimson. Flocks of these birds were at that time feeding on the glowing clusters profusely ripe upon the trees. Stationary insects are the staple food; to obtain which, they hop about grassy places, and are often seen to jump, or to run eagerly at their prey; on which occasions the long tail, continuing the given motion after the body has stopped, is thrown forward in an odd manner, sometimes nearly turning the bird head over heels. It is probably to protect the eyes from the stalks of weeds and blades of grass in these headlong leaps, that the projecting brows are furnished with a row of short but very stiff overhanging bristles; but what purpose was served by the high and thin knife-blade of a beak, I was ignorant, till informed by Mr. Hill, who observes that it “enables the bird to open out the soft earth, and seek for its insect food; it also facilitates its access to the vermin imbedded in the long close hair of animals. I am assured,” he adds, “that if a patch of cows’ dung be examined after Crotophagas have been searching for the larvæ of insects, it will be found furrowed as if a miniature plough had passed through it.”

The form of this organ has given occasion, in Hayti, where also it is common, to the appellation of “bout de tabac,” that is “bowl of tobacco pipe;” it is also called there Judeo.

The name Crotophaga, (tick-eater,) is no misnomer, as has been, without foundation, asserted by some who never saw the living bird. Almost every one in Jamaica is aware that the Savanna Blackbird, as well as the Grakle, feeds on the parasites of cattle. I made particular inquiries about this soon after my arrival, and was assured of the fact by persons who had witnessed it multitudes of times, and who could not “mistake” the Blackbird for the Grakle, their whole form, voice, and motions, being different.

Afterwards, however, I had repeated opportunities of personal observation on this point. One day I noticed a cow lying down, around which were four or five Blackbirds, hopping on and off her back, and eagerly picking the insects from her body; which service seemed in no wise unpleasing to her. I have also seen them leaping up on cows when grazing; and, on another occasion, jumping to and from a horse’s back; and my lad Sam has repeatedly observed them clinging to a cow’s tail, and picking insects from it, as far down as the terminal tuft. Had cattle been pastured near where I resided, I should doubtless have had many more ocular demonstrations: but the evidence is amply sufficient. In some of these cases, the occurrence was close to me, so that there was no possibility of deception, especially as, being aware of the conflicting statement, I looked with the more interest to satisfy myself.

But stationary insects are not the only prey of the Crotophaga; in December, I have seen little groups of them engaged in the evenings, leaping up from the pasture about a yard into the air, doubtless after flying insects, which they seemed to catch. One day in March as I sat at dinner, my attention was arrested by what seemed to be a green bird chased by several Crotophagas, near the top of a lofty tree at some distance, I presently saw that it was a very large lepidopterous insect; it flew over the woods about a quarter of a mile before I lost sight of it, when it appeared to alight on the top of a tree. The birds did not pursue the chase far. I have seen one with a dragon-fly in its beak, which it had just caught, but it may have been while resting. At another time I saw that a Blackbird had actually made prey of one of our little nimble lizards (Anolis). These circumstances show, that like the Toucans, the Ani is to some extent omnivorous.

Though its usual mode of progression on the ground is by hopping, or rather bounding, the feet being lifted together, the Blackbird is seen occasionally to run in a headlong manner for a short distance, moving the feet alternately. He is fond of sitting in the morning sun on a low tree with the wings expanded; remaining there perfectly still for a considerable time. In the heat of the day, in July and August, many may be seen in the lowland plains, sitting on the fences and logwood hedges with the beaks wide open, as if gasping for air; they then forget their usual loquacity and wariness. Often two or three will sit in the centre of a thick bush, overhung with a matted drapery of convolvolus, whence they utter their singular cry in a calling tone, as if they were playing at hide-and-seek, and requiring their fellows to come and find them.

The statement that the Blackbird builds in company, forming an immense nest of basket-work by the united labours of the flock, is universally maintained by the inhabitants of the colony. It is said to be usually on a high tree, where many parents bring forth and educate a common family. Mr. Hill, whose statements in Jamaican Ornithology are worthy of unlimited confidence, observes: “Some half-a-dozen of them together build but one nest, which is large and capacious enough for them to resort to in common, and to rear their young ones together. They are extremely attentive to the business of incubation, and never quit the nest, while sitting, without covering the eggs with leaves, to preserve them at an equal temperature.” The only instance in which I ever met with a nest, while it is not conclusive, is rather in favour of this opinion than the opposite. In July I found a Blackbirds’ nest in a Bastard Cedar (Guazuma); it was a rather large mass of interwoven twigs lined with leaves. Eight eggs were in the nest, and the shells of many more were also in it, and scattered beneath the tree. The eggs were about as large as a pullet’s, very regularly oval, of a greenish blue, but covered with a coating of white chalky substance, which was much scratched and eroded on them all, and which was displaced with little force. On being broken, the interior was peculiar; the glaire was less tenacious than usual, but more jelly-like, yet at the same time thinner in consistence; but what surprised me was, that in each egg this glaire filled at least three-fourths of the whole space, while the yolk, flattened in form, not larger in diameter than a coat-button-mould, and about twice as thick, was adhering to one side and end. It was pale, and resembled in appearance that of a hen’s egg, when just turned by boiling. I examined several, and found all alike.

I close this account with some pleasing notes of the species by Mr. Hill. “Though the Savanna Blackbird is classed among the scansorial or climbing tribe of birds, and has the yoke-formed foot,—like another class of the Cuckoo tribe among us, of which we have four or five different kinds,—it is generally a downward, not an upward climber. It enters a tree by alighting on the extremity of some main branch, and gains the centre of the foliage by creeping along the stem, and searching for its insect food. Unlike, however, our Cuckoos, which are solitary-feeding birds, it does not range from stem to stem, and search the tree through. The Blackbirds, moving in flocks of half-dozens, tens, and twelves, seldom penetrate far among the leaves. They glance along the branches rapidly, and silently quit the tree they have visited, by dropping one by one on some inviting spot on the green sward under them, or start away suddenly, the whole possé together, to some near-by thicket, to which one among them generally leads with that peculiar shrill and screaming cry that distinguishes them from every other bird of the field.

“These Savanna Blackbirds are favourites with me. Other winged wanderers have their season, but these are the tenants of the field all the year round. Their life is in the sunshine. Wherever there are open lands in tillage or pasture, with intermingled trees and shrubs, there these social birds frequent:—always familiar and seemingly fearless, but never omitting to set their sentinel watchmen to sound their cry when any one obtrudes nearer upon them than to a certain space within their social haunts.

“After a passing fall of rain, one of our sudden mid-day thunder showers for instance, when the full burst of sunshine, bright and fierce, breaks again on the freshened landscape;—the first bird seen creeping out from the thicket to dry his wings, and regain the fields, is the Savanna Blackbird. The Mocking-bird, ready as he is with his song, to gladden the landscape once more, is seldom before the shrill Blackbird, in breaking the hush that succeeds the overpast shower. Que-yuch, que-yuch, que-yuch is heard from some embowered clump not far off, and a little stream of Blackbirds, with their long tails and short gliding wings outstretched in flight, are seen straggling away to some spot, where insect-life is stirring, in the fresh, damp, and exuberant earth. The sun is levelling its slant beam along the plains, and the sea-breeze is breathing fresh and fragrant with a sense of reviving moisture from the afternoon showers, que-yuch, que-yuch, que-yuch is heard again, hastily and anxiously repeated; and the little birds are seen scrambling into the hedge-rows, and the Blackbirds are pushing from the outer limbs of the solitary thicket, from whence they sounded their cry of alarm, to gain the inward covert of the leaves. A hawk with silent stealth is skimming along the bordering woodland, gliding occasionally downward to the lesser bushes in the Savanna. The tocsin of the Blackbird, however, has warned the whole field, and not a voice is heard, and not a wing is stirring.

“In the hot and sultry days when the dews have ceased to fall, and all vegetation is parched and languid, the Blackbirds are seen wending their way at an early hour of the afternoon to the riverside, trooping in little parties. They have found some spot where an uprooted tree has grounded in the shallow stream. Here they are perched, some tail upward, drinking from the gliding waters below, some silent and drooping, some pluming themselves, and some in the sands that have shoaled about the embedded trunk of the tree, washing in the little half-inch depths of water. They will continue here till sunset, when they will start off laggingly, the signal being first given by some one of the flock, who has announced, that it is time to seek their coverts for the night, with the still peculiar cry of que-yuch.”

I am inclined to attach very little importance to the wrinkles on the beak as indicating specific difference: these, as well as the form and size of the organ, varying considerably in individuals from the same locality; the result, I have no doubt, of age.

Of all our Doves, none is so exclusively arboreal as this. The Bald-pate, the Blue Pigeon, and the Ring-tail are essentially tree-doves, but I have seen the first feeding on the ground, and the second is often seen running; but all who are acquainted with this bird’s haunts and habits concur in affirming that he is never seen to put his feet upon the earth. Though it is probable that he must occasionally procure gravel, to aid in the comminution of his hard food, and that, when the resources of the wild-pines are exhausted in the long droughts, he must descend to drink at the mountain ponds, or gully springs, it seems that he cautiously selects his occasion, when unwitnessed by human eyes. And yet it is said not to be a shy bird, nor, at certain times, difficult to obtain by those who have made themselves acquainted with its habits. It inhabits the most recluse and dense mountain forests, where few are able to follow it, but the negro fowlers. The penetration of steep mountain-woods, abounding in prickly bushes, and tangled, beyond all description, by twining and pendent lianes, many of which are formidably spinous, where there is nothing like a pathway, and the ground is strewn with enormous masses of honey-combed limestone, over whose sharp points the hunter must often climb at the risk of his neck,—or with a loose rubble that slips from beneath the feet, and causes continual falls, is an enterprise that demands no small degree of courage, temper, and perseverance. The naked feet of the negroes catch hold of the rocky projections, almost like the hind hands of the monkey, and they can proceed with rapid and noiseless step; while the shoes of the white man, in his slow and painful progress, betray, by the displacing of stones, and the crackling of twigs, his approach to the wary bird, while yet far away. The musquitoes also, that, thirsting for blood, and swarming in such situations, dance around his face with their maddening hum, and soon inflame head, hand, and foot with their pungent stings, make a tyro long to be out again, almost before he has lost sight of the open sky of the clearing. But it is the presence of these most annoying insects, which affords an opportunity of obtaining the highly prized Ring-tail. This bird appears to suffer more from their stings than others; or else its superior sagacity has taught it a resource of which others are ignorant, or unwilling to avail themselves. It is aware that these little insect-pests cannot abide smoke, and wherever the blue clouds curl gracefully through the tall trees from the woodman’s fire, the Ring-tail is said to resort thither, if within the neighbourhood, and solace itself with a temporary suspension of insect assaults. But, alas! it is only to expose itself to a more fatal peril, for the negro sportsmen have marked the habit, and fail not to take advantage of it. Whenever they have noticed the birds feeding on the berries of any particular tree, they take an early opportunity of kindling a fire beneath it, near which they conceal themselves, so as to watch the tree. The birds begin to arrive, and are shot down by the fowler one after another; the repeated flashes and reports, and the falls of their companions, driving the survivors away for a few moments only from the attractive spot, to which they again and again return till the gunner’s ambition is satisfied. They are frequently brought to Kingston, Savanna-le-Mar, and the other towns, and are eagerly purchased for the table; though, as the distance which they are carried usually prevents their arrival on the day they are killed, they are almost invariably deplumed and drawn, and the inside strongly peppered before they are sent to market. Hence specimens for the naturalist, are to be obtained only by a special expedition. Of the three superlative delicacies of which the natives of Jamaica boast, the Ringtail holds the undisputed pre-eminence. The others are the Fresh-water Mullet, and the Black Land-crab. Dr. Chamberlaine (Comp. to Jam. Alm. 1840) mentions this bird as “the most luscious dainty of his class, or of any other. I am acquainted,” he further observes, “with no bird that the sportsman pursues, that can be compared to the Ring-tail Pigeon, for the richness, the delicacy, and the tenderness of his flesh. He is, during the months of September, October, and November, a mass of luscious fat, and his plump and well-enveloped flesh acquires for him a superiority over that of all his tribe.” It is a common thing, at the period of their high condition, for birds shot from a tall tree to burst asunder with the fall.

The Ring-tail is stated invariably to perch near the middle of a tree, usually in the fork of the principal limbs; where, when seated, it will remain quietly looking down at the fowler, perhaps within a few yards of his head. The centre of those trees which are clothed with a dense tangled mass of withes or creepers, is preferred; and it is asserted that on no occasion is this bird to be seen perched on an exterior twig or branch. The Blue Pigeon sometimes manifests the same predilection; but with him it is only when the gusty “norths,” rocking the flexible branches, would make his seat on them uncomfortable if not insecure.

The Ring-tail will sometimes leave his solitudes, and come down to eat the berries of missletoe, growing on sour-sop and other trees. A friend has seen four thus engaged on a tree in the house-yard. It eats the seed of the yam also in the provision ground.
