THE RAVEN.

The RAVEN (_Corax nobilis_), as the principal member of this group is

called _par excellence_, is recognisable by its lengthy body, broad,

long, and pointed wings, the third quill of which considerably exceeds

the rest in length; the tail is of moderate dimensions, and graduated.

Its plumage is short, glossy, and uniformly black; the eyes of the old

birds are brown, those of the young blueish black, and those of the

nestlings pale grey. The length of this species is about two feet, its

breadth four and a quarter; the wing measures seventeen inches, and the

tail nine and three-quarters.

This Raven is spread over a much larger portion of the world than

any of its congeners; it inhabits the whole of Europe, as well as a

great part of Asia, and is met with in the countries extending from

the Altai Mountains to Japan. It is at present uncertain whether the

very large Raven met with in North America is the same or only a

similar species. Throughout some parts of Europe these birds dwell

comparatively apart from man, preferring to inhabit such localities as

mountains, dense forests, or rocky coasts, while others, that frequent

the northern, southern, or eastern coasts of our continent, live on

comparatively friendly terms with the lord of the soil, from whom their

many objectionable habits do not meet with the same retribution as in

the more central or western lands. Ravens usually live in pairs, and

remain constantly together throughout their lives, passing their time

principally in flying in company with each other over the surrounding

country. When on the wing, their movements are extremely beautiful, they

alternate between a rapid and direct flight, produced by a powerful

stroke of the wings, these, like the tail, being kept outspread, and a

hovering motion, that takes the form of a series of gracefully described

circles, seeming to be produced without the slightest effort on the part

of the birds, who occasionally amuse themselves by dropping suddenly to

a distance of some feet, and then continuing their way as before. Upon

the ground their gait is distinguished by a most absurd assumption of

dignity, the upper portion of the body being held considerably raised,

whilst they gesticulate with the head in a most laughable attempt to

keep time with the movements of the feet. While perched the feathers are

generally kept quite close, those only upon the head or neck being spread

or ruffled when the creature is under the influence of strong emotion:

the wings are always kept slightly raised from the body.

By the rest of its congeners the Raven would seem to be regarded with

abhorrence, for they will fall upon and attack it with the utmost

animosity: and should it attempt to join a party of other species of its

family, they greet it with as noisy demonstrations of terror, as if the

intruder were a Hawk or a Buzzard, and compel it at once to retire from

amongst them. In its relations with man nothing can exceed the prudence

and wariness of the Raven, its fear of molestation being so strong as to

compel it even to desert its nestlings should an enemy approach, although

its attachment to its offspring is usually both warm and constant. The

voice of this bird is varied, and its manner of chattering to its mate

during the period of incubation even more peculiar and incessant than

that of the Magpie.

In voracity the Raven has but few equals, for not only will it eat

almost all kinds of food, including fruit, corn, and every description

of insect, but it will seize upon and devour creatures exceeding itself

in size, and attack not only almost any quadruped from a hare to a

mouse, but boldly engage the Seagulls in combat, when those birds seem

inclined to dispute its right to invade their nests and despoil them

of their young. Boldness and cunning, strength and dexterity, all seem

to be united in the character of this daring marauder; it will attack

domestic fowls, ducks, or young geese, and chase and destroy not only

partridges, but hares and pheasants. In some parts of Ireland the Raven

may be seen picking up its food in the vicinity of houses in company with

dogs and cats, or prowling about on the sea-shore in search of fish.

During the spring it destroys numbers of young lambs, or amuses itself

by driving Eider Ducks from their nests to devour their eggs, and when

it has satiated itself will conceal those that remain beneath the sand;

even horses are not free from the attacks of these birds, which will

settle upon the back of any wounded or suffering animal, and can only

be dislodged after long and violent efforts. Eagles they do not venture

to contend with, but follow in their wake in the hope of obtaining the

remnants of their prey; in short, nothing that can be overcome by their

strength, craft, or audacity is spared; they will even, it is said,

devour the aged or nestlings belonging to their own species. We are

assured that mussels form a part of the Raven's diet, the bird having

first carried them into the air, and let them fall from a considerable

height, to break their shells upon the rocks or stones beneath; they

will also eat the hermit crab, which is obtained by rapping its shell

until the unsuspecting creature creeps out to ascertain the cause of

the disturbance. Despite the cruel and rapacious disposition of these

birds, their deeds are not always deeds of evil; on the contrary, great

and valuable are some of the services they often render to man, insomuch

that by some nations they are regarded with the utmost favour--the Arabs,

indeed, look upon them with such superstitious reverence as to imagine

them to be immortal, and in Greenland and Iceland they are allowed to

run tame about the houses. On the other hand, in the Canary Islands they

are held in the utmost detestation by the shepherds, who maintain that

they constantly peck out the eyes of young goats and lambs, and on this

account wage an exterminating war against them.

The eyrie of the Raven is generally situated in the hole of a rock, or

the summit of a high and inaccessible tree; it is usually about one

foot deep, and from two to three feet wide; the exterior is formed of

small branches, lined with a layer of twigs, and the interior, which is

about nine inches in diameter, and four or five inches in depth, bedded

with wool, fine grass, and similar materials, the utmost caution being

employed by these birds, both when seeking materials and when building

the large and strong cradle which year after year is resorted to for the

purposes of incubation. The eggs, usually four or five in number, are

large, and of a green colour, marked with brown and grey spots. Ravens

are by no means deficient in care for their young, and labour incessantly

to satisfy their ever-craving beaks with all kinds of animal food; should

fear compel them to quit their charge, they perch as near the little

family as safety will permit, and testify by plaintive cries and anxious

flutterings their desire to return to their brood. When fully fledged,

the young do not entirely leave the nest, but return every evening for

some weeks, in order to pass the night in the snug warmth that it affords

them, and perhaps to receive instruction during the day, as to the means

to be employed in obtaining food; they probably leave their protectors

only when the autumn approaches. When tamed the Raven may be taught to

speak with facility. It will likewise imitate a great variety of sounds,

and those who can overlook its thievish propensities and tiresome habits

will often derive considerable pleasure from watching its amusing tricks,

and cultivating its really high capacities.

The VULTURE RAVENS (_Corvultur_), as two African members of this group

have been called, are birds exceeding the Common Raven in rapacity

as well as in size. Both these species have unusually thick beaks,

compressed at their sides, the upper mandible being so decidedly bent as

closely to resemble that of a Vulture; the third and forth quills are

longer than the rest; the tail is rather large, and slightly graduated.

The WHITE-NECKED VULTURE RAVEN (_Corvultur albicollis_) and the

THICK-BILLED VULTURE RAVEN (_Corvultur crassirostris_), the former

a native of the Cape of Good Hope, and the latter an inhabitant of

Abyssinia, are much alike in their general appearance; both are of

a glossy coal black, except upon the nape, which is white. In the

Abyssinian species the sides of the neck gleam with a rich purple, and

the rest of the coat is lighted up with a blue refulgence; the small

feathers upon the wing-covers near the shoulder are a mixture of chestnut

and black; and the white marks upon the nape extend upwards till they

reach the top of the head; the eye is reddish brown, the feet and beak

black, the latter being tipped with white. The length of this species is

about three feet two inches, the length of wing one foot five inches, and

of the tail nine inches. According to Rüppell, this bird inhabits the

Abyssinian highlands, and is often found at an altitude of 5,000 feet

above the level of the sea. Le Vaillant tells us that the Vulture Raven

is voracious, daring, extremely noisy, and very filthy in its habits,

subsists principally upon carrion, and destroys large numbers of sheep

and gazelles, tearing out their eyes and tongue and then devouring them.

Were it possible, it would readily contend with buffaloes, elephants,

cattle, or horses, but is compelled to rest content with following them

and relieving such as are tormented with various parasites to which

they are liable, the poor creatures often allowing the Vulture Raven to

peck their hides till the blood flows rather than endure the perpetual

irritation from which they suffer so severely. The nest of the Vulture

Raven is built in October, and placed upon the branches of a tree; it

is formed of twigs, lined with some soft material. The four eggs of

which a brood is composed are green, spotted with brown. This species

never migrates, but remains from one year's end to another near the

same locality; occasionally it associates with its congeners, but never

partakes of the food on which they subsist.
