For what reason Linnæus applied the trivial name of Mango to this

Humming-bird I have no knowledge; that it could have no connexion with

the mango tree is evident, since that tree was not introduced into the

western world till long after his time. It was perhaps a native name.

It is not confined to Jamaica, but seems more widely spread than most

of these tiny birds. Lesson says, “The Mango inhabits Jamaica, and, as

it appears, not only the greater Antilles, but also Terra Firma, and

even, it is said, Brazil and Guiana.” Hence it has long been familiar

to naturalists. It is the Largest or Blackest Humming-bird of Sloane.

Lesson, in “Les Colibris,” has given no less than four figures of this

species in different ages, pl. xiii. to xv., but I cannot say much in

their praise.

The _Polythmus Mexicanus_ and _Polythmus Jamaicensis_ of Brisson,

both refer, without doubt, to the present bird. It is _le plastron

noir_ of Buffon. Whether _Trochilus gramineus_ of St. Domingo, which

has been supposed to represent this species in that sister island, is

really any thing more than a variety, I have no means of determining.

My valued friend Mr. Hill, in writing to me observes, “Buffon makes

his ‘_plastron noir_’ of Jamaica, common to Brazil and St. Domingo.

The compensatory bird in St. Domingo is much more green than Jamaica

specimens; i. e., with a less disposition to assume the violet and

purple in the changes of light, and with decidedly a less prevalence of

what Buffon designates the ‘beau noir velouté.’”

I may add that both the birds alluded to have been familiar to my

friend, from personal observation in both islands.

The appellation by which the Mango Humming-bird is familiarly known to

the negroes in the colony, is that of “Doctor bird,” which, however,

is sometimes applied also to Polytmus. It is thus explained by Mr.

Hill:—“In the old time, when costume was more observed than now,—the

black livery among the gayer and more brilliant Trochilidæ represented

the Doctor. It might with equal propriety have been the parson; but

parsons were less known than doctors, in the old times of the colony.”

Though occurring at all seasons, I have not found the Mango abundant

at any; it is, indeed, far less common than either _Polytmus_ or

_Humilis_. It affects the lowlands in preference to the mountains, and

open places rather than the deep woods; yet it is rarely seen to suck

the blossoms of herbs or shrubs, as Humilis does, but like Polytmus

hovers around blossoming trees. The bunch of blossom at the summit of

the pole-like papaw-tree (_Carica papaya_) is a favourite resort of

this species, particularly at sunset. This habit I observed and took

advantage of very soon after my arrival, for there was a fine male

papaw tree in profuse bloom close to the door at Bluefields, which the

Mango frequented. Wishing to keep these birds in captivity, I watched

at the tree one evening with a gauze ring-net in my hand, with which I

dashed at one, and though I missed my aim, the attempt so astonished

it, that it appeared to have lost its presence of mind, so to speak,

flitting hurriedly hither and thither for several seconds before it

flew away. The next evening, however, I was more successful. I took

my station, and remained quite still, the net being held up close to

an inviting bunch of blossom: the Humming-birds came near in their

course round the tree, sipped the surrounding blossoms, eyeing the net;

hung in the air for a moment in front of the fatal cluster without

touching it, and then, arrow-like, darted away. At length one, after

surveying the net, passed again round the tree; on approaching it the

second time, perceiving the strange object to be still unmoved, he took

courage, and began to suck. I quite trembled with hope: in an instant

the net was struck, and before I could see anything, the rustling of

his confined wings within the gauze told that the little beauty was

a captive. I brought him in triumph to the house and caged him; but

he was very restless, clinging to the sides and wires, and fluttering

violently about. The next morning, having gone out on an excursion for

a few hours, I found the poor bird on my return, dying, having beaten

himself to death. I never again took this species alive.

The sustenance of the Humming-birds is, I feel assured, derived

almost exclusively from insects. That they seek the nectar of flowers

I readily admit, and that they will eagerly take dissolved sugar or

diluted honey in captivity I also know; but that this would maintain

life, or at least vigour, I have great reasons for doubting, which I

shall mention in the history of the following species. I have dissected

numbers of each of our species, and have invariably found the little

stomach distended with a soft black substance, exactly like what we

see in the stomachs of the Warblers, which being put into clear water,

and examined with a lens, proves to be entirely composed of minute

insects. The interior of flowers is almost always inhabited by very

small insects, and it is I believe principally to pick out these that

the Humming-birds probe the tubular nectaries of blossoms. Wilson

has mentioned his having observed the Ruby-throat (_T. Colubris_)

pursuing flies on the wing. I also have witnessed the same thing in our

species, many times. I have seen the Mango, just before night fall,

fluttering round the top of a tree on which were no blossoms, and from

the manner in which it turned hither and thither, while hovering in a

perpendicular position, it was manifest that it was catching minute

insects. This species when flying often flirts and flutters the tail in

a peculiar manner, throwing it in as he hangs perpendicularly in mid

air, when the appearance of the broad lustrous feathers, expanded like

a fan, is particularly beautiful.

The pugnacity of the Humming-birds has been often spoken of; two of

the same species can rarely suck flowers from the same bush without a

rencontre. Mango, however, will even drive away another species, which

I have never observed the others to do. I once witnessed a combat

between two of the present species, which was prosecuted with much

pertinacity, and protracted to an unusual length. It was in the month

of April, when I was spending a few days at Phœnix Park, near Savanna

le Mar, the residence of my kind friend, Aaron Deleon, Esq. In the

garden were two trees, of the kind called the Malay apple (_Eugenia

Malaccensis_), one of which was but a yard or two from my window. The

genial influence of the spring rains had covered them with a profusion

of beautiful blossoms, each consisting of a multitude of crimson

stamens, with very minute petals; like bunches of crimson tassels; but

the leaf-buds were but just beginning to open. A Mango Humming-bird

had, every day, and all day long, been paying his devoirs to these

charming blossoms. 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

the beak 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 on 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-coloured light,—added

much to their beauty. A little Banana Quit, 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

neighbouring 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. I have alluded to the preference which different species

appear to manifest, for different blossoms; I may add that I have

observed _Mellisuga humilis_ come and suck the flowers of a Cashew tree

(_Anacardium_), without noticing those of the Malay apple close by,

while Mango seems to despise the former for the latter.

The lustrous glow reflected from the sides of the neck of the

adult male, may be unperceived on a careless examination. In such

Humming-birds as I have examined, (perhaps in all,) the iridescence of

those portions of the plumage that are changeable, is splendid in the

ratio of the acuteness of the angle formed by the incident ray and the

reflected one. Thus the plumes of the neck of Mango appear to advantage

in a room with a single light, only when the beholder stands with his

back to the window, and has the bird before him and facing him. Then

the perpendicular band down the throat and breast, which seems composed

of the richest black velvet, is bounded on each side by a broad band

of glowing crimson, mingled with violet. It must be borne in mind,

that _some_ of the brilliant hues of Humming-birds are permanent, not

changeable colours.

I have never met with the nest of this species; but Sam informed me in

June that he had observed one near Morgan’s Bridge, in Westmoreland.

It was on a dead tree, and was placed _upon_ a twig, but being full

fifteen feet from the ground he could not examine it. He, however, saw

the Mango Humming-bird fly out of it, and presently return. A nest,

presented to me by my friend Mr. Hill, ticketed as that of Mango,

is now before me. It has evidently been constructed to stand upon a

horizontal twig, which the bottom has embraced. It is cylindrical

externally, the bottom being nearly flat. Its height is 1¹⁄₂ inch; its

external diameter a little more; its internal diameter about 1 inch;

the hollow, which is a little overhung by the margin, is cup-shaped,

about ⁷⁄₈ inch deep. It is composed almost entirely of the down of the

gigantic silk-cotton tree, (_Eriodendron anfractuosum_) intermixed at

the bottom with a little true cotton. The sides are tightly banded

round with the threads of spiders’ webs, very neatly put on, and the

whole exterior is studded with a minute whitish lichen, so profusely

as almost entirely to conceal the down, without at all injuring the

symmetry of the form. It is a most compact and beautiful little

structure.

The down of the cotton-tree is the material ordinarily chosen by

all our Humming-birds for the construction of their nests. The tree

attains a giant size and diameter, and throws out to a vast distance

its horizontal limbs, each equalling in its dimensions an ordinary

forest tree. It is one of the few in those tropical islands, which are

deciduous: the fierce blasts called “norths,” which prevail in January

and February, pouring down from the mountains, quickly lay it bare.

I have seen an enormous tree in full foliage, almost leafless in an

hour; the leaves filling the air, like flakes of snow in a driving

storm. While it is yet denuded, the pods appear at the ends of the

branches, resembling green walnuts: these ripen before the leaves bud,

and opening, give freedom to a mass of fine silky filamentous down,

which is borne away upon the wind. The filaments are so fine, that at

this season, April and May, they are imbibed with the air we breathe,

being almost impalpable, and are considered to aggravate pulmonary

affections. The tufts so scattered, the Humming-birds and others of the

feathered tribes, diligently collect, and that not only on the ground.

I have been amused to observe a Mango Humming-bird suspending himself

in the air, over against a puff of down, which was slowly borne along

upon a gentle breeze, picking at it and drawing filaments from it,

doubtless with a view to nest-building.
