Though shy enough before, the birds now become wonderfully tame and

fearless; they not only unhesitatingly take possession of the platforms,

boxes, ledges, and other contrivances prepared for them, but allow

themselves to be driven to the most suitable places, without being at

all alarmed or disturbed at the presence of their conductors. They come

into the immediate neighbourhood of the solitary huts of their keepers,

and will enter them in search of a snug corner in which to build;

indeed, it not unfrequently happens that adventurous females will take

possession of bedrooms, stables, and other similar localities, to the

great inconvenience and discomfort of the keeper's wife. At first the male

bird always accompanies his mate in these pedestrian excursions in search

of lodgings, which generally occupy them during the morning; about noon

they fly away towards the fiords or swim about upon the open sea; but

towards evening they come on shore to pass the night. While the female is

employed in laying her eggs, the male watches over the nest with great

perseverance and devotion; but no sooner is the number of eggs complete,

and the female begins in earnest the work of incubation, than the male

flies off, leaving both nest and wife, and hastens to join the society

of other males who may be disporting themselves far out at sea. Upon the

rocks and "scaars" upon the coast of Norway these forlorn widowers may be

seen playing together by hundreds. The nest of the Eider Duck is a very

simple affair, consisting merely of a few twigs, stalks of seaweed, blades

of grass, straw, and similar materials, such as can be picked up in the

immediate neighbourhood, heaped together in the most slovenly manner; the

rougher the framework, however, so much thicker and more valuable is the

rich lining of down--the costly toll which the breeding birds have to

pay to the masters of the soil for their temporary residence. After the

lapse of a few days, the female sits most assiduously; in places where

she is accustomed to the sight of men she will not stir even should they

approach her nest; she simply bows her head to the ground, and slightly

spreads her wings so as to make herself as inconspicuous as possible. The

colour of her plumage generally coincides so exactly with that of the

surrounding rocks, that to an unpractised eye the bird is with difficulty

distinguishable from the ground on which it sits. We have more than once

had convincing proof of the efficacy of this mode of concealment, in the

shape of a sharp bite on the leg, inflicted by the beak of a brooding

female, of whose presence we were quite unaware before--at the last

moment--she flew away. Those females who happen to have taken up their

abode in the vicinity of men will allow themselves to be taken up from the

nest while their eggs are examined, after which they immediately settle

down again to brood, without showing the slightest desire to escape.

Frequently we have sat close to their nests for hours together, have

stroked their feathers, put our hands between their bodies and their eggs

to note the temperature, and yet few of them have stirred from the spot.

Some of them would occasionally bite our fingers as if in play, but the

majority testified neither timidity nor annoyance. Some we purposely took

to a little distance from their nesting-place and placed upon the ground,

but they would immediately waddle back to their domicile, arrange the down

around the eggs, and quietly resume their position, as if nothing had

happened. When left quite to themselves the brooding females quit their

nests regularly every morning, taking care, however, to cover their eggs

warmly with down, so that they may not be chilled during their absence;

having done this, away they fly out to sea, and dive assiduously for half

an hour in search of food, and in this short period manage to fill their

crops almost to bursting with various kinds of shell-fish, after which

they return at once to their charge. The males are much more timid than

the females, even when with them at the breeding season or whilst keeping

watch over their nests. Should any one approach, they immediately get

into a terrible flurry, toss their heads, call loudly to their wives, and

after blustering for a little time, fly off to sea, whence they anxiously

watch the proceedings of the disturber of their quietude. After the lapse

of twenty-five or twenty-six days, the young ones break their shells and

make their appearance; they are beautiful little creatures, clad in rich

parti-coloured down. From the first moment of their birth they are well

able both to swim and to dive; they also walk with considerable facility,

even better than their mother, who takes them, before their downy coat

has had time to dry, down to the sea. Should the breeding-place be far

from the sea, and the departure of the little flock be unusually delayed,

the keepers frequently come to their assistance, and, putting the entire

brood into a basket, walk with them to the shore, followed by the waddling

parents, who seem quite satisfied with the arrangement.

[Illustration: EIDER DUCKS AT HOME.]

The sea, indeed, is the safest place for these helpless nestlings, as

there they can most readily escape from their natural enemies the Falcons,

Ravens, and Skuas. Very frequently several mothers, accompanied by their

little families, consort together, and then they present to the observer

a very attractive spectacle. Should the parent birds perceive that they

are followed by a boat, they at once begin to paddle away with all their

strength, hoping to escape from their pursuers, and it is not till the

boat has come close upon them that they decide upon taking wing; by

so doing they are of course compelled to desert the young birds, who,

however, seem very well to understand how to provide for their own safety,

as they immediately make for the land, and scrambling on to the shore, may

be seen running nimbly in search of some convenient hiding-place, dropping

down between stones, or concealing themselves behind slight inequalities

of the ground, from which they are scarcely distinguishable. Should the

threatened danger pass away, they will be found after a little time

hastening back to the sea, into which they immediately plunge, and paddle

away directly from the shore, until they are joined either by their own

mother or by some other elderly female belonging to their flock. Should

their mother be killed, the young, if unable to do without assistance,

at once join some other family, into which they are received without

the slightest reluctance, and tended and cared for by the old birds

precisely as if they were their own offspring. The instinct for brooding

in the Eider Ducks is indeed very remarkable; they will even steal each

other's eggs in order to brood upon them. The nestlings grow rapidly, and

often within a week from their birth are well able to procure their own

food; they remain, nevertheless, in company with their parents till the

early part of the following year. In their earliest infancy they are fed

with small crustaceans and other soft-bodied animals; at a later period

they live for the most part upon bivalve shell-fish, but likewise feed

willingly on fishes, or indeed on any small marine animals that they may

meet with. Although the Eider Ducks constitute a considerable portion of

the wealth of the countries they inhabit, they are by no means cared for

and protected as they might be. Intelligent landholders, whose property

the breeding-places are, take the opportunity while the birds are laying

to remove some of their eggs, and thus succeed in making them lay a

greater number than they otherwise would do. Moreover, they are content to

wait patiently until the breeding-time is over before they gather the down

from their nests. More generally, however, neither birds nor eggs are

taken the least care of. Notwithstanding that their flesh is not by any

means palatable, these Ducks are continually persecuted and slaughtered,

and the consequence is, that in Spitzbergen and other localities where the

sale of the Eider-down used to be reckoned by the hundredweight, it is

now reckoned only by pounds. Malmgren assures us that it is a rare thing

to see young birds in the autumn; and the bird-catchers are loud in their

complaints of a scarcity, for which they have only their own improvidence

to blame. In Greenland the diminution, although not quite so conspicuous,

is still very great, not more than a thousand pounds being now collected

there annually. "Formerly," says Holboell, "the gross quantity of down

procured in South Greenland in the course of a year was 5,007 lbs., and

North Greenland produced about half that quantity." According to the usual

reckoning a dozen nests yield a pound weight of the raw material, so that

every year 104,520 birds were not only despoiled of their down but also

robbed of their eggs.

THE TRUE EIDER DUCK, OR ST. CUTHBERT'S DUCK.

The TRUE EIDER DUCK, or ST. CUTHBERT'S DUCK (_Somateria mollissima_),

has the cheeks, chin, back, and breast white, the latter with a reddish

tinge. Front and sides of the head black; nape, to the throat, pea-green;

quills and tail brown, marked on the wings with velvet-black. The eye is

reddish brown, the beak greenish yellow, the foot olive-green. The length

of this bird is twenty-four inches, the breadth forty; the length of wing

eleven inches, and length of tail three inches and a half. The female is

smaller than the male, and her plumage rust-red, marked on the head and

neck with longitudinal brown streaks, elsewhere with crescent-shaped black

spots; her under side with deep brown, slightly lined with black. After

the breeding season the plumage of the male loses much of its beautiful

glistening appearance, both head and neck become blackish grey, more

darkly clouded, the shoulders greyish black, and the region of the crop

yellowish white, marked with black and rust-brown upon the borders of the

individual feathers. It seems probable that this change of plumage is

not produced by moulting, but by a gradual change in the colour of the

feathers.

This valuable Duck is met with throughout the northern regions of the

globe, its range extending from Jutland to Spitzbergen, and from the west

coast of Europe along its northern shores to Greenland and Iceland. It is

a constant resident in some of the northern parts of England and Scotland,

and has the name of St. Cuthbert's Duck from the numbers that nest in that

island. Its most southern breeding-places are upon the Island of Sylt and

other small Danish islands in the same latitude, and from thence north it

is met with in continually increasing numbers. In Iceland, Greenland, and

Norway, it is very abundant, and is preserved with the utmost strictness.

Their nests along the coast of Norway, we are told, produce, from the down

they yield, on an average, a profit of five pounds a-piece in the year;

so that a small barren rock, frequented by these birds, becomes a very

valuable property, and has often been the subject of litigation between

Norwegian landholders. Some years ago the Eider Fowl were killed in such

numbers that their extinction in that country seemed imminent, but in 1847

the Norwegian Parliament passed a law for their relief, and since that

time their pursuers have been obliged to confine themselves to robbing

the nests; the consequence is that these Ducks are now very plentiful,

and from the perfect security in which they live have attained a degree

of impudent assurance unsurpassed by the London Sparrows, or their own

distant connections on the ornamental waters in our parks. In the town

of Tromsöe they come to the house doors to be fed, and walk about as if

strongly impressed with the consciousness of their own importance. In

the northern parts of Great Britain these birds are seen assembling in

groups along the shores of the mainland about April, from whence they

cross to the adjacent islands early in May. The nest of this species,

which contains from four to ten (generally six or eight) well-shaped,

smooth-shelled eggs, usually of a dusky greyish green, is formed of fine

seaweed, and is lined, after the eggs are deposited, with down from the

mother's breast, placed so thickly that the eggs are completely hidden

from view. The down from a single nest, when cleansed, although sufficient

in bulk to fill a man's hat, seldom weighs more than one ounce. In

northern countries the business of robbing the nests of this valuable

material begins soon after the eggs are laid, the female replacing it by a

fresh supply from her breast, until it is quite bare, when the male bird

in turn strips himself to provide a warm covering for his young. "In a

month's time," says Mr. Selby, "the little family are led or carried in

their parent's bill to the water, where they swim and dive with facility;

the mother meanwhile carefully watching over them to defend them from

their biped foes, and feigning lameness to lure their pursuers from the

spot."

[Illustration: THE EIDER DUCK (_Somateria mollissima_).]

"The care which the mother takes of her young," says Audubon, "cannot

be exceeded. She leads them gently in a close flock in shallow waters,

where, by diving, they procure food, and at times, when the young are

fatigued and at some distance from the shore, she sinks her body in the

water and receives them on her back, where they remain several minutes.

At the approach of their merciless enemy, the Black-backed Gull, the

mother beats the water with her wings, as if intending to raise the spray

around her, and, on her uttering a peculiar sound, the young dive in all

directions, while she endeavours to entice the marauder to follow her, by

feigning lameness, or she leaps out of the water and attacks her enemy,

often so vigorously that, exhausted and disappointed, he is glad to fly

off, on which she alights near the rocks, among which she expects to find

her brood, and calls them to her side. Now and then I saw two females

which had formed an attachment for each other, as if for the purpose of

more effectually contributing to the safety of their young, and it was

very seldom that I saw these prudent mothers assailed by the Gulls."

We must not omit to mention that the eagerness of these birds for brooding

is so great, that, when robbed of their eggs, they have frequently been

known to steal the eggs or even the young of others of their species.

In its natural state the Eider Duck subsists upon small fish, molluscs,

crustaceans, and fish spawn, but when kept confined will eat grain. The

flight of this species, which is steady and rapid, is usually carried on

near the surface of the water; it dives with facility, and is capable of

remaining submerged for a considerable time.

THE KING EIDER.

The KING EIDER (_Somateria spectabilis_) has the bill, the sides of

which are elevated, arched and ridged, surrounded by a fine black band;

a similar band runs from the base of the under mandible down each side

of the neck. The upper head is grey, the cheeks are sea-green, the neck,

back, and sides of the rump white, the front of the breast is light

flesh-red; the scapulars, lower part of back, wings, tail, and belly, are

white, and the rest of the feathers black; tertials, as in the preceding

species, deflected. The eye is brown, beak red, and foot reddish. The

female is distinguishable from that of the True Eider by her light reddish

brown plumage, and by the structure of the base of the bill.

General Sabine states (in the Appendix to Sir E. Parry's first Voyage)

that these birds were abundant in the North Georgian Islands, their nests

being placed on the ground in the neighbourhood of fresh-water ponds, and

their food consisting of the aquatic vegetation. Sir J. C. Ross says,

"Vast numbers of this beautiful Duck resort annually to the shores and

islands of the Arctic Regions in the breeding season, and have on many

occasions afforded a valuable and salutary supply of fresh provision to

the crews of the vessels employed on those seas. On our late voyages

comparatively few were obtained, although seen in very great numbers.

They do not retire far to the south in the winter, but assemble in large

flocks, the males by themselves, and the females with their young brood

are often met with in the Atlantic Ocean, far distant from any land, where

the numerous crustaceans and other marine animals afford them abundance of

food."

This species, which very rarely occurs in Great Britain, was found, on one

occasion, according to Dr. Latham, about June, at Papa Westra, one of the

Orkney Islands. The eggs, six in number, rather smaller than those of the

True Eider Duck, were embedded in down, and placed on a rock overhanging

the sea. Nuttall states that the eggs of this bird are whitish, while

Yarrell describes them as pale green, and Audubon as of a uniform dull

greenish hue. Latham tells us that in Greenland, where the King Ducks are

common, the natives assemble in canoes, and by their shouts terrify the

birds, which dive to avoid them; but as the place where they are about to

emerge is betrayed by the bubbling of the water, their pursuers follow

them, and the same game being several times repeated, the birds are at

length tired out and easily secured.

* * * * *

The WESTERN or STELLER'S EIDER DUCK (_Somateria_ or _Heniconetta

Stelleri_) is a smaller species, still more beautifully coloured and

marked. In the male the head, nape, and sides of neck are white, a spot on

the forehead, and a transverse band at the back of the head are green, a

circle round the eye, the fore and hinder neck, the rump, tail, and points

of the quills are black. The upper wing-covers and shoulders are white,

striped with dark blue. The under side, as far as the blackish brown

centre of the belly, is yellowish brown. In the plumage of the female

reddish brown predominates. The eye is brown, the beak grey, and the foot

greenish grey. The Western Eider Duck was first described by Steller, from

specimens which he obtained in Kamschatka, where it builds on inaccessible

rocks. But few specimens of this rare Duck have been shot in England. This

species is exclusively a sea bird, is never seen entering the estuaries of

rivers, and breeds among rocks and precipices. It flies in large flocks.

* * * * *

The SCOTERS (_Oidemia_) are birds of considerable size, with remarkably

dark plumage. Their beak is moderately long, broad, irregularly swollen

at its junction with the forehead, and bright coloured. The tarsi are

short, the toes long and large, and the wings of medium length; the tail,

which is wedge-shaped, consists of fourteen feathers; the soft and velvety

plumage only exhibits colour on the head and wings. All the species

belonging to this group are inhabitants of high latitudes, and breed

within the Arctic Circle.

THE VELVET SCOTER.

The VELVET SCOTER (_Oidemia fusca_), one of the species most common

in Great Britain, is coal-black, with the exception of a spot beneath

the eye, and another on the wing, which are white; the beak is bright

yellowish red, marked with black at the edges and at its base; the

feet are pale flesh-red, varied with black at the joints; the eye is

pearl-white. The female is dark brown, with the exception of a white

spot in the region of the ear, a white patch upon the wing, a yellowish

bridle-streak, and a grey place upon the centre of the breast. Her eye

is brown, her beak black, and her foot greenish yellow. The length of

this species is twenty-four inches; the breadth forty inches; the length

of the wing twelve inches, and that of the tail three inches and a

half. The range of the Velvet Scoter extends from the northern parts of

Scandinavia eastward as far as America. In the north of Russia and Siberia

it is common. During its excursions it not only visits our shores, but

goes still further southwards, and has occasionally been seen even upon

the coasts of Spain and in Greece, but rarely shows itself inland. It

makes its appearance in our latitudes late in the year, generally about

the middle of November or the beginning of December, and returns to its

northern home early in the spring. In the neighbourhood of the Gulf

Stream, where the sea remains open, it may be met with throughout the

winter, frequenting the fjords and bays, sometimes in numerous flocks, at

others only in small parties, and seldom visits the shores.

The Velvet Scoter walks and flies badly, but swims well and dives

admirably. Naumann states that it is less shy than the generality of its

race, a statement which we cannot subscribe to; in Norway, at least, we

have always observed it to be one of the most timid and circumspect of

diving birds. The food of these Ducks consists principally of bivalve

shell-fish; in their breeding-places they may likewise procure insects,

worms, and probably small fishes; but it is upon the bivalve molluscs

that they chiefly feed, and to obtain these they will even leave their

brooding-ground and fly out to sea. They have also been observed to feed

upon vegetable substances.

Upon the mountain lakes of Southern Norway the Velvet Scoters breed

with tolerable regularity; and further to the north there is hardly a

sheet of water of this description, if not too remote from the sea, upon

which their young are not to be found. About the middle of June their

rudely-constructed nests may be met with hidden in bushes or high grass,

or amid tufts of rushes. The nest itself is constructed of coarse sticks,

stalks, and leaves, loosely heaped together, and lined with down plucked

from the body of the female. The eight or ten eggs constituting a brood

are elongated, smooth, and shining, and of a reddish yellow colour. The

young remain in their native lakes until fully able to fly, and do not

betake themselves to the sea till the end of October.

* * * * *

The FEN DUCKS (_Aythya_) are handsome, strongly-built birds, with

moderately long beaks, which are not dilated at the base; short,

broad-soled feet; moderately long, pointed wings, and smooth plumage.

The range of the members of this group extends from the Arctic Circle

to the tropics. They do not inhabit very high latitudes, and only visit

the south during their migrations. They may, therefore, be considered as

properly belonging to the temperate zone. During the winter months they

are to be met with in Southern Russia and the low countries bordering on

the Danube, also in Greece, South Italy, Spain, and throughout the north

of Africa. These birds make their migrations by night, great numbers of

them flying together in large flocks, generally without any regular order,

but sometimes arranged in converging oblique lines. In the spring they are

usually seen in pairs or in small parties. During the summer they visit

lakes of fresh water, large ponds, morasses, or fens having a considerable

surface of water of sufficient depth, sometimes resorting to smaller ponds

which may happen to be in the neighbourhood. As regards their locomotive

powers, these Ducks are decidedly the best endowed of their family--they

can walk tolerably well, but, being very unwieldy, they do not willingly

come upon dry land, and then only to repose upon some sandbank, or beat

up any masses of reeds that may be lying on the margin of the pond. When

swimming their body is not so deeply immersed as is that of some of their

congeners; they cut through the waves, however, with the same rapidity,

and dive as quickly as any of their neighbours. Their flight is hasty and

performed by frequent strokes of their wings, that make a perceptible

rushing sound, but do not propel them very quickly through the air;

nevertheless, they do not seem to become fatigued so quickly as might be

expected.

During the summer time the Fen Ducks live almost entirely on vegetable

substances; bulbous roots, buds, and tender shoots of trees, succulent

leaves, blossoms and seeds of water-plants, constitute the staple of their

diet; they will, however, likewise catch aquatic insects, fishes, and pond

mollusca; in fact, they seem to like variety. During their migrations they

appear more partial to animal food, and when they indulge in this to any

extent, their flesh, at other times excellent food, acquires a somewhat

disagreeable flavour.
