CHAPTER XVII

THE EAGLE

“If it were my purpose to give you a systematic and scientific account

of birds, instead of acquainting you with the various species useful to

agriculture, I ought to have begun with birds that hunt by day and to

have postponed my talks on those that hunt by night; in other words,

the eagle, the falcon, and the hawk should have been described first.

But should you ask me why, I should be rather at a loss for a

satisfactory answer. For want of a better let us content ourselves with

this one: the first do their work by day, the second at night. But the

eagle and the others of that group live at our expense, while the

horned owl and its kind render us a great service by holding in check

what would else be a disastrous multiplication of rodents.

Consequently, in point of usefulness, the night-bird comes first.

“But this is contrary to all usage, both scientific and popular, which

puts the eagle first in the list of birds. Do we not say of the eagle

that it is the king of birds? Why has this title been given to the

fierce bandit, the murderer of lambs? I should be puzzled to answer

this question did I not know man’s inclination to glorify brute

strength even though he himself may be its victim. You, my children,

will find that out only too soon, to your sorrow. Plunder on a grand

scale appeals, alas, to something in our faulty human nature that makes

us excuse it; nay, more, that makes us glorify it; whereas productive

toil, useful to all, leaves us cold or even disdainful. The falcon is a

ravisher of our hen-houses, a bloodthirsty marauder of our dove-cotes;

and we hold it in high esteem, calling it a noble bird. Shall we, then,

never learn to judge animals and men by their true worth, their real

usefulness? Let us hope that as so many fine minds have worked, are

working, and always will work to bring about this miracle, you, my

children, will some day follow their example. Work for this end with

all your power, and blessings be upon you if you succeed in giving some

additional strength, however little it may be, to this common effort

put forth by all men of light and leading.

“I shall discuss but briefly the birds of prey whose activities are

confined to the daylight hours. They are nearly all bandits, nothing

else, living at our cost by robbery and murder. From the fact that they

hunt by day, never at night, they are called diurnal or day birds of

prey. The brightest light does not dazzle them. It is even said of the

eagle and others of this class that they can look straight at the sun,

and this is credited to them as an added title of nobility. But there

is no great merit in this performance when once you know how they shade

their eyes in accomplishing it. They have three eyelids to each eye:

first, two like ours, an upper and a lower, which close in sleep, and

then a third, which is semi-transparent and is withdrawn completely

into the corner of the eye when the bird has no use for it, but when

needed comes out from under the other two, which remain open, and

serves as a curtain. If the light is too bright or the bird wishes to

look toward the sun, it has merely to draw over the eye this third

eyelid, this eye-shade, through the semi-transparency of which the rays

of light enter the pupil in a much subdued intensity. There you have

the whole secret of the eagle’s bold look in facing the sun.”

“I could do as much if I shaded my eyes with a curtain,” Emile

declared.

“All these birds are furnished with a very strong beak having hooked

mandibles for dismembering their prey. Their claws are composed of four

separate talons to each foot, three of these talons pointing forward

and one backward. The talons are long, recurved, and grooved on the

under side, the grooves having sharp edges that they may the better cut

into flesh. The eagle’s bearing is bold, its looks stern, and its

flight marvelously powerful. Eagles like to circle about in the air, to

soar with scarcely a movement of the wings in the upper regions of the

atmosphere beyond our view. Nevertheless, even from this immense height

they can distinguish what is taking place on the earth’s surface below.

They explore every farm with their piercing eyes and inspect every

poultry-yard. Let a suitable prey show itself, and instantly the bird

swoops down with whistling wing, faster than lead would fall. The

unwary fowl is snatched from under the farmer’s very eyes.

“Fortunately, the eagle, the chief of these bandits, is a very rare

bird. In form it is large, measuring a meter and more from the tip of

the beak to the tip of the tail, and it is covered with brown plumage.

Its extended wings measure a span of nearly three meters. Its fierce

eye, overshadowed by a very prominent eyebrow, glows with a somber

fire. The eagle’s nest is known as its aery, and is flat instead of

bowl-shaped like other birds’ nests. It is a sort of solid floor made

of interwoven twigs and covered with a bed of rushes and heather. It is

commonly placed on the face of some steep and forbidding precipice and

between two rocks, the upper one of which overhangs and forms a kind of

roof for the nest. The eggs, two in number—sometimes, though rarely,

three—are of a dingy white spotted with red. The young eaglets are so

greedy that at the time of their rearing the aery is strewn with bits

of bleeding flesh. Some neighboring ledge of rock serves the parents as

slaughter-house and cutting-up bench. It is there that the hares and

rabbits, partridges and ducks, lambs and kids, seized in the plains and

carried in rapid flight to the lofty heights where the eagle makes its

home, are torn to pieces in order to be fed to the ever-hungry

eaglets.”

“Is the eagle really strong enough,” asked Emile, “to carry off a lamb

like that? I had heard it, but couldn’t believe it.”

“Nothing is less open to doubt,” his uncle assured him. “It would carry

you off if it found you alone in the mountains.”

“I could defend myself with a stick.”

“Possibly; but let me tell you an incident, one of many to be found in

the pages of an author whose word we may believe.

“Two little girls, one five years old, the other three, were playing

together when a medium-sized eagle suddenly swooped down upon the elder

and despite her companion’s cries, and in the very face of some workmen

who came hurrying to the spot, snatched her up into the air. Two months

later a shepherd found, on a rock half a league distant, the body of

the child half devoured and dried up.

“What do you think now of the eagle, the king of birds?”

“I think it’s a brigand of the worst kind,” affirmed Jules.

“Would you like to see an eagle in the act of hunting, witness its

fierce joy when it buries its hooked talons in the quivering flesh of

its prey? Then listen to this fine passage from the pen of that ardent

lover of birds, Audubon. The scene is laid far from here, in America,

and the eagle belongs to a different species from ours; but never mind,

the ways of these bandits are the same everywhere.

“‘To give you some idea of the nature of this bird, permit me to place

you on the Mississippi, on which you may float gently along, while

approaching winter brings millions of water-fowl on whistling wings,

from the countries of the north, to seek a milder climate in which to

sojourn for a season. The Eagle is seen perched in an erect attitude,

on the highest summit of the tallest tree by the margin of the broad

stream. His glistening but stern eye looks over the vast expanse. He

listens attentively to every sound that comes to his quick ear from

afar, glancing now and then on the earth beneath, lest even the light

tread of the fawn may pass unheard. His mate is perched on the opposite

side, and should all be tranquil and silent, warns him by a cry to

continue patient. At this well known call, the male partly opens his

broad wings, inclines his body a little downwards, and answers to her

voice in tones not unlike the laugh of a maniac. The next moment, he

resumes his erect attitude, and again all around is silent. Ducks of

many species, the Teal, the Wigeon, the Mallard and others, are seen

passing with great rapidity, and following the course of the current;

but the Eagle heeds them not: they are at that time beneath his

attention. The next moment, however, the wild trumpetlike sound of a

yet distant but approaching Swan is heard. A shriek from the female

Eagle comes across the stream,—for she is as fully on the alert as her

mate. The latter suddenly shakes the whole of his body, and with a few

touches of his bill, aided by the action of his cuticular muscles,

arranges his plumage in an instant. The snow-white bird is now in

sight: her long neck is stretched forward, her eye is on the watch,

vigilant as that of her enemy; her large wings seem with difficulty to

support the weight of her body, although they flap incessantly. So

irksome do her exertions seem, that her very legs are spread beneath

her tail, to aid her in her flight. She approaches, however. The Eagle

has marked her for his prey. As the Swan is passing the dreaded pair,

the male bird, in full preparation for the chase, starts from his perch

with an awful scream, that to the Swan’s ear brings more terror than

the report of the large duck-gun.

“‘Now is the moment to witness the display of the Eagle’s powers. He

glides through the air like a falling star, and, like a flash of

lightning, comes upon the timorous quarry, which now, in agony and

despair, seeks, by various manœuvres, to elude the grasp of his cruel

talons. It mounts, doubles, and willingly would plunge into the stream,

were it not prevented by the Eagle, which, long possessed of the

knowledge that by such a stratagem the Swan might escape him, forces it

to remain in the air by attempting to strike it with his talons from

beneath. The hope of escape is soon given up by the Swan. It has

already become much weakened, and its strength fails at the sight of

the courage and swiftness of its antagonist. Its last gasp is about to

escape, when the ferocious Eagle strikes with his talons the under side

of its wings, and with unresisted power forces the bird to fall in a

slanting direction upon the nearest shore.

“‘It is then, reader, that you may see the cruel spirit of this dreaded

enemy of the feathered race, whilst, exulting over his prey, he for the

first time breathes at ease. He presses down his powerful feet, and

drives his sharp claws deeper than ever into the heart of the dying

Swan. He shrieks with delight as he feels the last convulsions of his

prey, which has now sunk under his unceasing efforts to render death as

painfully felt as it can possibly be. The female has watched every

movement of her mate, and if she did not assist him in capturing the

Swan, it was not from want of will, but merely that she felt full

assurance that the power and courage of her lord were quite sufficient

for the deed. She now sails to the spot where he eagerly awaits her,

and when she has arrived, they together turn the breast of the luckless

Swan upwards, and gorge themselves with gore.’” [5]

“Poor swan!” was Emile’s pitying comment.
