Part 13

Mellisuga humilis.—+Mihi.+

Ornismya minima, +Less.+ Ois. M. 79. (nec auct.)

Male. Length 2⁷⁄₁₀ inches, expanse 3¹⁄₂, flexure 1¹⁄₂, rictus ⁵⁄₁₀, (nearly,) tail ⁸⁄₁₀, tarsus rather above ¹⁄₁₀, middle toe ¹⁄₁₀, claw ¹⁄₁₀.

Irides, beak, and feet black. Whole upper parts metallic-green; wings purplish-black; tail deep-black; chin and throat, white speckled with black; breast white; sides metallic-green; belly whitish, each feather tipped with green; vent white; under tail-coverts white, tipped faintly with green.

Female. Rather less; of a yellower green above, which descends half-way down upon the tail. Whole under parts pure white, unspotted, untinged with green; tail-feathers, except the uropygials, tipped with white.

Intestine 1⁹⁄₁₀ inch: no cæca.

That this is the species of which M. Lesson has figured the female in his Oiseaux Mouches, pl. 79, there can be no doubt. His figure is a very fair representation; though it is too slender, and the white mark behind the eye I cannot find: this, however, I do not wonder at, if, as is most probable, his figure was taken from a dried specimen. He says, “it is beyond contradiction the smallest of all those yet known, and without doubt is the ‘very little Humming-bird’ of voyagers. Its length is 2 inches and 4 lines.” But that it is the Trochilus minimus of Linnæus, Buffon, Edwards, and Latham, who can imagine, that puts any faith in testimony? Edwards’ figure, which is said to be “of its natural bigness,” measures 1⁴⁄₁₀ inch; that in the Pl. Enl. 276. fig. 1, is about 1³⁄₁₀; and Latham, who says expressly, “I have received this from Jamaica,” gives its total length 1¹⁄₄ inch, and that of its beak, 3¹⁄₂ lines. It is true the description as to colouring, &c., bears a very close resemblance to mine, but no one accustomed to the precision of science could mistake 2¹⁄₂ inches for 1¹⁄₄! Neither is it possible that these minute specimens can be the young of the present species; for nestling Humming-birds, even when not half-fledged, are very little less in size than the adult, and, when able to leave the nest, are scarcely to be distinguished as to dimensions. Moreover, having reared this species I can speak positively. But Mr. Bullock records having obtained in Jamaica a species whose body was but half an inch in length; this specimen is understood to have become the possession of the late George Loddiges, Esq., and I have been assured by an ornithological friend, who has seen it, that it is no larger than the species of the old naturalists. Under these considerations, Lesson’s name being manifestly misapplied, I have ventured to give to the present species, a new appellation, derived from its habit of buzzing over the low herbaceous plants of pastures, which our other species do not. The West Indian vervain (Stachytarpheta) is one of the most common weeds in neglected pastures, shooting up everywhere its slender columns, set round with blue flowers, to the height of a foot. About these our little Humming-bird is abundant during the summer months, probing the azure blossoms a few inches from the ground. It visits the spikes in succession, flitting from one to another, exactly in the manner of the honey-bee, and with the same business-like industry and application. In the winter, the abundance of other flowers and the paucity of vervain-blossoms, induce its attentions to the hedgerows and woods.

Yet Sloane describes his “Least Humming-bird,” (Jam. 308) as “about 1¹⁄₄ inch long, from the end of the bill to that of the tail,” while of his figure the bill alone measures ³⁄₄ inch, and the whole bird 2⁵⁄₈. As the worthy Doctor, however, is said to have taken his admeasurements with his thumb-nail, this slight variation is the less surprising.

I have sometimes watched, with much delight, the evolutions of this little species at the moringa tree already spoken of. When only one is present, he pursues the round of the blossoms soberly enough, sucking as he goes, and now and anon sitting quietly on a twig. But if two are about the tree, one will fly off, and, suspending himself in the air a few yards distant, the other presently shoots off to him, and then, without touching each other, they mount upward with a strong rushing of wings, perhaps for five hundred feet. Then they separate, and each shoots diagonally towards the ground, like a ball from a rifle, and wheeling round, comes up to the blossoms again, and sucks, and sucks, as if it had not moved away at all. Frequently one alone will mount in this manner, or dart on invisible wing diagonally upward, looking exactly like a humble-bee. Indeed, the figure of the smaller Humming-birds on the wing, their rapidity, their arrowy course, and their whole manner of flight, are entirely those of an insect; and one who has watched the flight of a large beetle or bee, will have a very good idea of the form of one of these tropic gems, painted against the sky. I have observed all our three species at one time engaged in sucking the blossoms of the moringa at Content; and have noticed that whereas Polytmus and Mango expand and depress the tail, when hovering before flowers, Humilis, on the contrary, for the most part, erects the tail; but not invariably.

The present is the only Humming-bird that I am acquainted with, that has a real song. Soon after sunrise in the spring months, it is fond of sitting on the topmost twig of some mango or orange tree, where it warbles, in a very weak but very sweet tone, a continuous melody, for ten minutes at a time: it has little variety. The others have only a pertinacious chirping.

The season of nidification seems to be as protracted in this, as in the former species; nor does the structure itself differ, except in being of about half the size. The small bushes of Lantana, so common by roadsides, and always covered with orange and yellow blossom, are favourite situations for the domestic economy of this minim bird. The smooth twigs of the bamboo also are not unfrequently chosen. It is not an uncommon thing in Jamaica, for a road up a mountain to be cut in zig-zag terraces to diminish the steepness; and, to prevent the lower side of such a road from crumbling away, stems of green bamboo are cut and laid in a shallow trench along the edge. Shoots spring from every joint, and presently a close row of living palisades are growing along the margin of the road, whose roots, as they spread, effectually bind together the mountain-side, and make the terrace perpetual; while, as they increase in height and thickness, they throw their gracefully-waving tufts over the way, like gigantic ostrich plumes, affording most refreshing shadow from the heat. Such a bamboo-walk, as it is called, winds up the steep side of Grand Vale mountain in St. Elizabeth’s, and here the nests of the Vervain Humming-bird are frequently met with.

One day in June, being up this road, I found two nests attached to twigs of bamboo, and one just commenced. Two parallel twigs were connected together by spiders’ webs, profusely but irregularly stretched across, and these held a layer of silk-cotton, which just filled up the space (about an inch square) between them. This was the base. The others were complete cups of silk-cotton exceedingly compact and neat, ornamented outside with bits of grey lichen, stuck about. Usually the nest is placed on a joint of a bamboo branch, and the diverging twigs are embraced by the base. The nest is about the size of half a walnut-shell, if divided not lengthwise, but transversely. To see the bird sitting in this tiny structure is amusing. The head and tail are both excluded, the latter erect like a wren’s: and the bright eyes glance in every direction. One of these contained two eggs, the other a single young nearly fledged, which, with the nest, I carried to Content to rear.

It is interesting to observe the cleanliness of animals; the dung of young birds would greatly inconvenience them in the nest, and probably cause disease; it is therefore wisely ordained that there should be some mode of getting rid of it. Swallows carry out the excrement of their young in their beaks; and this they are able to do, as at that early season it is enclosed in a tenacious jelly. I observed with admiration, and with adoration, of the tender mercy of God in directing such minutiæ as these, for the comfort of His creatures, that this little Humming-bird, while I was carrying it, elevating its body above the edge of the nest, in the bottom of which it ordinarily lay, ejected the alvine discharge in a forcible jet, to the distance of several feet.

This little nestling I attempted to rear, and had every prospect of succeeding, for it eagerly received the juice of sugar-cane, which I administered to it in a small quill, many times in the day, sometimes adding small insects, as in a former case. But on the third day I was necessitated to return to Bluefields, and rode fifteen miles with the bird in my hand, enclosed in an open box. I took every care of it; but whether from too long fasting, or from the shaking, or exposure to the sun, I know not, but it was dying when I arrived, and a few minutes put an end to its sufferings and my expectations.

Several times I have enclosed a nest of eggs in a gauzed cage, with the dam, taken in the act of sitting; but in no case did she survive twenty-four hours’ confinement, or take the slightest notice of her nest. When engaged in the attempt to domesticate a colony of Polytmus, an opportunity offered to add this minute species to my aviary. For at that time two large tamarind-trees very near the house were in full blossom, and round them the Vervain Humming-bird was swarming. I never saw so many of this tribe at once; they flocked together, as Sam truly observed, “like bees,” and the air resounded with their humming, as if in the neighbourhood of a hive. We caught several with the net, but could make nothing of them; they were indomitably timid. When turned into the room, they shot away into the loftiest angle of the ceiling, and there hovered motionless, or sometimes slowly turning as if on a pivot, their wings all the time vibrating with such extraordinary velocity as to be visible only as a semicircular film on each side. The fact that the extent of the vibration reached 180°, (or so nearly that it seemed to me such,) shews the immense power of the small muscles by which the wings are put in motion. Neither of our other species approaches either the rapidity or extent of this oscillation; and hence with this bird alone does the sound produced by the vibration of the wings acquire the sharpness of an insect’s hum. The noise produced by the hovering of Polytmus is a whirring exactly like that of a wheel put into rapid revolution by machinery; that of Humilis is a hum, like that of a large bee.

The spirit of curiosity is manifested by this little bird as well as by the larger species. When struck at, it will return in a moment, and peep into the net, or hover just in front of one’s face. The stories told of Humming-birds attacking men, and striking at the eyes with their needle-like bills, originated, I have no doubt, in the exaggeration of fear, misinterpreting this innocent curiosity.

Mniotilta varia.

Motacilla varia, +Linn.+ Sylvia varia, +Lath.+ Certhia maculata, +Wils.+ Mniotilta varia, +Vieill.+ Certhia varia, Aud. pl. 90.

Length 5 inches, expanse 8¹⁄₂, flexure 2⁸⁄₁₀, tail 2, rictus ⁶⁄₁₀, tarsus ⁸⁄₁₀, middle toe ⁶⁄₁₀.

This pretty bird, whose lot has been to oscillate in the systems of naturalists from the Warblers to the Creepers and from the Creepers to the Warblers, appears to have as much ambiguity in its manners as in its structure. One day I noticed it, and watched its proceedings, in one of the spreading Black-withes, that form large tangled masses of long slender branches over a clear space of mud in the morasses, the topmost stratum of which alone is furnished with leaves, but that dense enough, not only with its own foliage, but also with the drapery of convolvulus that is usually hung in profusion over it. The little bird was mounting from the bottom hopping from twig to twig, searching and picking as it went up; when it reached the bushy top, it suddenly descended, apparently by dropping perpendicularly to the bottom, where it picked a little about the mud, then mounted gradually, and dropped as before. After proceeding thus two or three times, I secured it.

At other times it affects the trunks of trees, even large ones, like a true Creeper, hopping diagonally up the perpendicular bole, and when at a good height, dropping down upon the wing, to alight again near the root, and proceed upward in another line. Now and then it stops to pick small insects from the crevices of the bark: and this sort of food I have always found in its stomach.

It is rather common in Jamaica during the winter months: we first saw it on the 26th of September, and last on the 30th of April.

The following interesting note accompanies a very correct drawing of this species by Robinson (Birds: large Folio):—“Motacilla alba et nigra varia.—It was pursued by a Hawk, and took sanctuary in Chateau-morant House. Mr. Holladay, overseer at Chateau in Clarendon, made me a present of the live bird, December 24th, 1760. It was very tame, and so hungry that it picked some feathers out of a dead bird, and ate them. It weighed somewhat less than two drachms.”
