Obs. This bird resembles no other in any considerable degree; and is,

therefore, to be easily distinguished. It seems to belong to some one of

the subdivisions of the old genus _Icterus_, or of _Xanthornus_, which

are so variously and confusedly given by professed systematists, that we

have no faith in any of them; which declaration, by the way, we have no

objection to embrace the present opportunity of extending to late

_opinionative_ classifications, in a manner rather general and

comprehensive. It is about full time for a true zoologist to appear, who

shall be capable of systematizing—of reducing to order and symmetry the

vast fund of facts and detached knowledge in natural history, which the

present age has accumulated. In our happier day-dreams, we have deemed

it inevitable that such a one must shortly appear. The great Anglo-Saxon

zoologist is yet to come.

PLATE XXII.—Adult Males.

The Humming Birds are peculiar to America. Until within a comparatively

recent period, about one hundred species were known to naturalists,—that

being the then considered large number enumerated in works published as

lately as within about twenty years. Discoveries of previously unknown

species in this family of birds have been numerous beyond precedent or

comparison with any other, notwithstanding the zeal and ability which

ornithology has commanded within the period mentioned. At present, there

are nearly three hundred ascertained species of Humming Birds. The large

and recent additions have resulted, in a great measure, from the

exploration of regions previously little visited or inaccessible,

principally in the northern part of South America, but also in Central

America and Mexico.

That portion of the continent of America between the Amazon as a

southern boundary, and the Rio Grande and Gila as a northern, embracing

New Grenada and Guiana, the whole of Central America and Mexico, to

which may be added the West India Islands, appears to be the most

productive of Humming Birds. Within that range, but especially in the

Republic of New Grenada, these splendid little birds are much the most

abundant, and it embraces nearly all of the most remarkable in form and

most beautiful in plumage. Southward into Brazil and Peru, and other

countries of South America, a considerable variety of species are also

found; but, in the north, that is to say, north of the line between

Mexico and the United States, we have few species of Humming Birds, and

even those give us but an imperfect idea of the gorgeous tints of their

relatives of the tropical regions of this continent.

Of the natural productions of America, these birds have attracted the

most universal admiration. Nor has it been, by any means, without

foundation. Nature appears to have exhausted herself in the lavish

profusion of colors of every tint and shade with which she has adorned

these gems of the animal world. They are the most splendidly colored and

at the same time the most diminutive of birds. Almost every color known

in art is to be met with in the plumage of some one or other of the

Humming Birds, and usually with a lustre more resembling that of the

most highly finished workmanship in metal, or of the most exquisite

precious stones, than the transient or easily destroyed appendages of a

delicate animal organization.

There are, however, some species which are quite plain in their

appearance, and present little or no trace of metallic or other

brilliant colors. Of these, one large species is perfectly black; others

are reddish-brown, or fulvous and plain dark green.

In size, the Humming Birds vary much. The Giant Humming Bird of Brazil,

which is the largest, though one of the plainest, is about the size of

the Chimney Bird of the United States, and several fine species of the

later discoveries in this group are but little smaller. Several species

are quite as large as the House Wren. On the other hand, there are

Humming Birds little larger than the Humble Bee of our meadows; and

there are many species of Beetles and other coleopterous insects, that

are much larger. The common ruby-throated Humming Bird of the United

States, is a medium-sized species, and of respectable dimensions when

compared with some of his pigmy brethren of the far South.

In form, too, they vary exceedingly. Some are very slender, and

apparently feebly constituted; others are comparatively quite robust.

There are species which have bills excessively long, the _Sword-bearer_

(_Trochilus ensiferus_), which is about the size of the House Wren, has

a bill longer than its body. So entirely disproportionate does the bill

of this species appear to be, that few persons, on seeing specimens for

the first time, can avoid a suspicion that it has been artificially

lengthened; and we have more than once heard it suggested on such an

occasion that this remarkable appendage could readily have been drawn

out by processes used by comb-makers. This exceedingly long bill is,

however, no inconvenience whatever to the gay little individual who is

responsible for it, luckily for him;—in fact, it assists him admirably

in procuring an entirely honest subsistence amongst the large

trumpet-flowers, and others with long tubular corollas, abundant in

tropical countries. No other known species has this organ of a length so

disproportionate, though there are several in which it is unusually long

for birds of such size. The bill is, however, scarcely of the same form

and shape in any two species. In some, it is perfectly straight and very

short; in others, as we have already observed, it is very long. Numerous

others have the bill curved downwards, or scythe-shaped, and a few

species have it turned upwards, presenting a very singular appearance.

Other curious appendages are to be met with in species of this family.

One group has exceedingly long tails, three or four times the length of

the body. Several Humming Birds have the outer feathers of the tail

long, and though narrow for the greater part of their length, suddenly

expanded at the end like a paddle or a spoon. These seem to form a group

or sub-genus of their own, and are also remarkable for having the upper

part of the leg (the _tibia_, and sometimes part of the _tarsus_)

covered with a thick mass of white downy feathers, presenting one of the

many instances of phenomena to which it appears almost impossible in the

present state of our knowledge, to assign a use in the economy of the

species. The wings in all Humming Birds are large, when compared with

those of many other birds, and are formed for long-continued and rapid

flight.

The food of the Humming Birds is now well ascertained to be principally

insects. We regard the conclusion, also, as unavoidable, that the

moisture contained in flowers is their drink only, and not capable alone

of supporting life. The tongue appears to be the principal organ used

both in capturing insects and in procuring the fluid portion of their

subsistence, and is constructed in a manner peculiarly adapted to these

purposes. It is long, and composed of two parallel tubes (like a

double-barrelled gun), furnished with the necessary apparatus of muscles

for sucking, and thus enabling the bird to reach the drops of moisture

or the fluid secretions contained very frequently in the corollas of

flowers, more abundant in some species than others. The tongue is

flattened, and sometimes barbed towards the end, or margined with

fringe-like appendages, evidently designed to be of material service in

feeding on minute flies or other small and soft insects. It admits, too,

of being darted outwards, like that of the woodpeckers, and in the

manner thus indicated it is very probable that their food is secured.

A large space on the throat is generally the most beautiful part of the

plumage of the birds of this family. Frequently, however, the top of the

head and the entire under parts of the body are clothed in colors of the

most surpassing brilliancy. The upper parts are usually plainer.

In the countries where these birds are most abundant, and even in others

of South America, some species of Humming Birds are spread over a vast

extent of territory;—other species are well known to be peculiar to

quite restricted localities. Many inhabit only the warmest

districts;—others are found only in mountain-valleys, thousands of feet

above the level of the sea. One of the most beautiful Humming Birds, the

Polytmus (_Trochilus polytmus_), a large species, having the plumage

mainly of a most exquisite green, with the top of the head jet black,

and with the tail excessively long, inhabits only the island of Jamaica,

and it is quite probable that every island of the West Indies produces

species which are to be found in no other. In some sections, they are

exceedingly numerous. Mr. Gosse, in his valuable volume on the Birds of

Jamaica, mentions having seen “no less than a hundred come successively

to rifle the blossoms within the space of half as many yards in the

course of a forenoon.” We have been informed of instances of the

ruby-topaz Humming Bird (_T. moschitus_) having occurred in the island

of Trinidad in even greater abundance.

In allusion to the general abundance of these birds in the countries

where they abound, and as a sketch of their habits, we transcribe the

following from “A Voyage up the Amazon,” from an excellent observer and

agreeable writer, our friend, Mr William H. Edwards, of New York:

“Wherever a creeping vine opens its fragrant clusters, or wherever a

tree-flower blooms, may these little birds be seen. In the garden, or in

the woods, over the water, everywhere, they are darting about;—of all

sizes, from one that might easily be mistaken for a different variety of

bird, to the tiny Hermit (_Trochilus rufigaster_), whose body is not

half the size of the bees buzzing about the same sweets. Sometimes they

are seen chasing each other in sport with a rapidity of flight and

intricacy of path the eye is puzzled to follow. Again circling round and

round, they rise high in mid-air, then dart off like light to some

distant attraction. Perched upon a little limb, they smooth their plumes

and seem to delight in their dazzling hues; then starting off leisurely,

they skim along, stopping capriciously to kiss the coquetting flowerets.

Often, two meet in mid-air and fight furiously, their crests and the

feathers on their throats all erected and blazing, and altogether

pictures of the most violent rage. Several times we saw them battling

with large black bees, who frequent the same flowers, and may be

supposed to interfere often provokingly. Like lightning, our little

heroes would come down, but the coat of shining mail would ward of their

furious strokes. Again and again would they renew the attack, until

their anger had expended itself by its own fury, or until the apathetic

bee, once roused, had put forth powers that drove the invader from the

field.”

The Mexican Humming Birds have been, until recently, but little attended

to, and even at this time are by no means well known. In an interesting

volume by Mr. William Bullock, a Fellow of the Linnean Society of

London, “Six Months Residence and Travels in Mexico” (London, 1824), a

work that contains much information on the natural history, and

especially the ornithology, of that country, there is a chapter

exclusively devoted to the Humming Birds. From it, we make the following

extract, which may be regarded as the more interesting, as some of the

species alluded to may be found hereafter in those parts of the United

States contiguous to Mexico:

“In Mexico, the species of Humming Birds are numerous. Near the capital,

on my arrival, scarcely one was to be seen; but in the month of May and

June, numbers were found in the Botanic Garden, in the centre of the

city; and, by offering a reward to the Indians, many were brought to me

alive. I had nearly seventy in cages, which, with attention and care, I

kept living for some weeks; and could I have devoted my whole attention

to them, I have no doubt of the possibility of bringing them alive to

Europe.

“It is probable the whole of them feed on insects; numbers I am certain

do so, having watched them attentively in the Botanic Garden at Mexico,

in pursuit of their minute prey; and in the yard of the house in which I

resided at Themascaltepec, where one of them took entire possession of a

pomegranate tree in blossom, on which he sat the whole day, catching the

small flies that came to the flowers.

“Although, like the Robin and other birds of Europe, in a state of

nature, they are extremely tenacious of any intrusion of their own

species on their dominions, yet, in captivity, when several kinds have

been confined together, I never observed the least inclination to

quarrel, but have seen the smaller take what appeared to be

unwarrantable liberties with those of five times their size and

strength;—thus, when the perch has been occupied by the great

blue-throated one, the diminutive Mexican Star has settled on the long

beak of the former, and remained perched on it some minutes, without its

offering to resist the insult.

“Europeans who have seen only the stuffed remains of these little

feathered gems in museums, have been charmed with their beautiful

appearance; but those who have examined them whilst living, displaying

their moving crests, throats, and tails, like the peacock in the sun,

can never look with pleasure on their mutilated forms. I have carefully

preserved about two hundred specimens, in the best possible manner, yet

they are still but the shadow of what they were in life. The reason is

obvious; for the sides of the laminæ, or fibres of each feather, being

of a different color from the surface, will change when seen in a front

or oblique direction; and as each lamina or fibre turns upon the axis of

the quill, the least motion, when living, causes the feathers to change

suddenly to the most opposite hues. Thus the one from Nootka Sound (_T.

rufus_) changes its expanded throat from the most vivid fire color to

light green; the topaz-throated does the same, and the Mexican Star

changes from bright crimson to blue.

“The sexes vary greatly in the plumage in many species, so much so, that

it is with difficulty we recognize them. The male and female of the

Mexican Star (_Cynanthus Lucifer_) could not have been known had they

not been seen constantly together, and proved to be so by dissection.

They breed in Mexico in June and July, and the nest is a beautiful

specimen of the architectural talent of these birds; it is neatly

constructed with cotton or the down of thistles, to which is fastened on

the outside, by some glutinous substance, a white flat lichen resembling

ours. The female lays two eggs, perfectly white, and large for the size

of the bird, and the Indians informed me they were hatched in three

weeks, by the male and female sitting alternately. When attending their

young, they attack any bird indiscriminately that approaches the nest.

Their motions, when under the influence of anger or fear, are very

violent, and their flight rapid as an arrow; the eye cannot follow them,

but the shrill, piercing shriek which they utter on the wing, may be

heard when the bird is invisible, and often led to their destruction by

preparing me for their approach. They attack the eyes of the larger

birds, and their sharp needle-like bill is a truly formidable weapon in

this kind of warfare.

“Nothing can exceed their fierceness when one of their own species

invades their territory during the breeding season. Under the influence

of jealousy, they become perfect furies; their throats swell, their

crests, tails, and wings, expand; they fight in the air (uttering a

shrill noise), till one falls exhausted to the ground. I witnessed a

combat of this kind near Otumba, during a heavy fall of rain, every

separate drop of which I supposed sufficient to have beaten the puny

warriors to the earth.

“In sleeping, they frequently suspend themselves by the feet, with their

heads downwards, in the manner of some parrots.

“These birds were great favorites with the ancient Mexicans. They used

the feathers as ornaments for their superb mantles in the time of

Montezuma, and in embroidering the pictures so much extolled by Cortez.

Their name signifies, in the Indian language, beams or locks of the sun.

The feathers are still worn by the Indian ladies as ornaments for the

ears.”

It may be properly remarked here that the statement made by Mr. Bullock,

of the habit of these birds sleeping with their heads downwards, has

attracted considerable attention, and it has been thought probable that

he may have been mistaken, or misinformed, not having been confirmed by

subsequent naturalists. It may, however, apply only to some species.

The pugnacity of these little birds is almost universally alluded to by

writers who have enjoyed opportunities of observing them in the

countries where they abound. A Humming Bird of any size, even the

smallest, is not on that account less a fighting character, and jealous

of whatever rights and privileges he considers himself entitled to. But

as both of the authors above quoted, have alluded to this point, we beg

the indulgence of the reader to lay before him another extract

especially relating to this hostility of disposition, and happily

illustrative of the fights and feuds of the Humming Birds. It is from

the very pleasant and valuable little work, previously mentioned, on the

Birds of Jamaica, by Mr. Philip Henry Gosse; and the species alluded to,

the Mango Humming Bird (_T. mango_), is one which is considerably larger

than the common ruby-throated species of the United States. It is

abundant in the West Indies, and in some parts of South America, and it

occasionally visits the shores of Florida. It is figured by Mr.

Audubon:—

“A Mango Humming Bird had, every day, and all day long, been paying his

_devoirs_ to these charming blossoms” (the Malay apple, _Eugenia

malaccensis_). “On the morning to which I allude, another came, and the

manœuvres of these two tiny creatures became highly interesting. They

chased each other through the labyrinth of twigs and flowers, till, an

opportunity occurring, the one would dart with seeming fury upon the

other, and then with a loud rustling of their wings, they would twirl

together, round and round, until they nearly came to the earth. It was

some time before I could see, with any distinctness, what took place in

these tussles; their twirlings were so rapid as to baffle all attempts

at discrimination. At length, an encounter took place pretty close to

me, and I perceived that the beak of the one grasped that of the other,

and thus fastened, both whirled round and round in their perpendicular

descent, the point of contact being the centre of the gyrations, till,

when another second would have brought them both to the ground, they

separated, and the one chased the other for about a hundred yards, and

then returned in triumph to the tree, where, perched on a lofty twig, he

chirped monotonously and pertinaciously for some time;—I could not help

thinking, in defiance. In a few minutes, however, the banished one

returned, and began chirping no less provokingly, which soon brought on

another chase and another tussle. I am persuaded that these were hostile

encounters, for one seemed evidently afraid of the other, fleeing when

the other pursued, though his indomitable spirit would prompt the chirp

of defiance; and, when resting after a battle, I noticed that this one

held his beak open, as if panting. Sometimes they would suspend

hostilities to suck a few blossoms, but mutual proximity was sure to

bring them on again with the same result. In their tortuous and rapid

evolutions, the light from their ruby necks would now and then flash in

the sun with gem-like radiance; and as they now and then hovered

motionless, the broadly-expanded tail,—whose outer feathers are

crimson-purple, but when intercepting the sun’s rays, transmit

orange-colored light—added much to their beauty. A little _Banana Quit_

(_Certhiola flaveola_), that was peeping among the blossoms in his own

quiet way, seemed now and then to look with surprise on the combatants;

but when the one had driven his rival to a longer distance than usual,

the victor set upon the unoffending Quit, who soon yielded the point,

and retired, humbly enough, to a neighboring tree. The war, for it was a

thorough campaign, a regular succession of battles, lasted fully an

hour, and then I was called away from the post of observation. Both of

the Humming Birds appeared to be adult males.”

In the United States, there have been discovered as yet not more than

five species of Humming Birds, including that which is presented to the

reader in our present plate. They are the ruby-throated Humming bird

(_Trochilus colubris_), which is the much-admired little species

everywhere common in the summer-time, in the States on the Atlantic; the

Mango Humming Bird (_T. mango_), an abundant South American and West

Indian species that occasionally visits Florida, as above stated; the

Anna Humming Bird (_T. Anna_), a species of California and Mexico, the

most beautiful of the northern species, and which derives additional

interest from the fact that it was named by an eminent French

naturalist, in honor of Anna, Duchess of Rivoli, whose husband, General

Massena, Duke of Rivoli, the distinguished officer of the armies of the

Emperor Napoleon I., founded the ornithological collection which now

belongs to the Academy of Natural Sciences of Philadelphia. In addition

to these, are the rufous-throated or Northern Humming Bird (_T. rufus_),

a western species, which extends its range on the Pacific coast to a

high northern latitude, and the bird now before us. Another species or

two have been named as inhabiting California, without it being stated

whether the upper or lower divisions of that country was intended. They

are not known to inhabit that portion which is one of the States of this

Union, though it is quite probable that others of the numerous Mexican

species will be found extending their range into the western and

southwestern territories.

Within the limits of the United States, the Humming Bird now before the

reader, has been noticed only by Dr. Heermann, whose fine collection

made in California contained numerous specimens. He detected it in one

locality only, which was the burying-ground at Sacramento city. There

several pairs remained during the season of incubation, and reared their

young, finding suitable food and protection amongst the flowering

plants, with which, with great feeling and propriety, that last

resting-place of the emigrant and stranger has been adorned.

Dr. Heermann represents the nest as composed of fine mosses, lined with

the feathery down of various seeds, and containing two white eggs. He

saw this bird also at Guaymas, in Mexico.

The figures in our plate are of the size of life, and represent adult

males. The plant represented is _Odontoglossum Cervantesii_, a native of

Mexico.
