THE GREAT BLACK-BACKED GULL. [Great Black-backed Gull.] |
Genus | LARUS MARINUS, Linn. [Larus marinus.] |
High in the thin keen air, far above the rugged crags of the desolate
shores of Labrador, proudly sails the tyrant Gull, floating along on almost
motionless wing, like an Eagle in his calm and majestic flight. On widely
extended pinions, he moves in large circles, constantly eyeing the objects
below. Harsh and loud are his cries, and with no pleasant feeling do they come
on the winged multitudes below. Now onward he sweeps, passes over each rocky
bay, visits the little islands, and shoots off towards the mossy heaths,
attracted perhaps by the notes of the Grouse or some other birds. As he flies
over each estuary, lake, or pool, the breeding birds prepare to defend their
unfledged broods, or ensure their escape from the powerful beak of their
remorseless spoiler. Even the shoals of the finny tribes sink deeper into the
waters as he approaches; the young birds become silent in their nests or seek
for safety in the clefts of the rocks; the Guillemots and Gannets dread to look
up, and the other Gulls, unable to cope with the destroyer, give way as he
advances. Far off among the rolling billows, he spies the carcass of some
monster of the deep, and, on steady wing, glides off towards it. Alighting on
the huge whale, he throws upwards his head, opens his bill, and, louder and
fiercer than ever, sends his cries through the air. Leisurely he walks over the
putrid mass, and now, assured that all is safe, he tears, tugs, and swallows
piece after piece, until he is crammed to the throat, when he lays himself down
surfeited and exhausted, to rest for awhile in the feeble sheen of the northern
sun. Great, however, are the powers of his stomach, and ere long the
half-putrid food which, vulture-like, he has devoured, is digested. Like all
gluttons, he loves variety, and away he flies to some well-known isle, where
thousands of young birds or eggs are to be found. There, without remorse, he
breaks the shells, swallows their contents, and begins leisurely to devour the
helpless young. Neither the cries of the parents, nor all their attempts to
drive the plunderer away, can induce him to desist until he has again satisfied
his ever-craving appetite. But although tyrannical, the Great Gull is a coward,
and meanly does he sneak off when he sees the Skua fly up, which, smaller as it
is, yet evinces a thoughtless intrepidity, that strikes the ravenous and
merciless bird with terror.
If we compare this species with some other of its tribe, and mark its great
size, its powerful flight, and its robust constitution, we cannot but wonder to
find its range so limited during the breeding season. Few individuals are to be
found northward of the entrance into Baffin's Bay, and rarely are they met with
beyond this, as no mention is made of them by Dr. RICHARDSON in the Fauna
Boreali-Americana. Along our coast, none breed farther south than the eastern
extremity of Maine. The western shores of Labrador, along an extent of about
three hundred miles, afford the stations to which this species resorts during
spring and summer; there it is abundant, and there it was that I studied its
habits.
The farthest limits of the winter migrations of the young, so far as I have
observed, are the middle portions of the eastern coast of the Floridas. While
at St. Augustine, in the winter of 1831, I saw several pairs keeping, company
with the young Brown Pelican, more as a matter of interest than of friendship,
as they frequently chased them as if to force them to disgorge a portion of
their earnings, acting much in the same manner as the Lestris does toward the
smaller Gulls, but without any effect. They were extremely shy, alighted only
on the outer edges of the outer sand-bars, and could not be approached, as they
regularly walked off before my party the moment any of us moved towards them,
until reaching the last projecting point, they flew off, and never stopped while
in sight. At what period they left that coast I am unable to say. Some are
seen scattered along our sea-shores, from the Floridas to the Middle States,
there being but few old birds among them; but the species does not become
abundant until beyond the eastern extremities of the Connecticut and Long
Island, when their number greatly increases the farther you proceed. On the
whole of that extensive range, these birds are very shy and wary, and those
which are procured are merely "chance shots." They seldom advance far up the
bays, unless forced to do so by severe weather or heavy gales; and although I
have seen this bird on our great lakes, I do not remember having ever observed
an individual on any of our eastern rivers, at a distance from the sea, whereas
the Larus argentatus is frequently found in such places.
Towards the commencement of summer, these wandering birds are seen
abandoning the waters of the ocean to tarry for awhile on the wild shores of
Labrador, dreary and desolate to man, but to them delightful as affording all
that they can desire. One by one they arrive, the older individuals first. As
they view from afar the land of their birth, that moment they emit their loud
cries, with all the joy a traveller feels when approaching his loved home. The
males sooner or later fall in with the females of their choice, and together
they proceed to some secluded sand-bar, where they fill the air with their
furious laughs until the rocks echo again. Should the student of nature happen
to be a distant spectator of these meetings, he too must have much enjoyment.
Each male bows, moves around his mate, and no doubt discloses to her the ardour
of his love. Matters are managed to the satisfaction of all parties, yet day
after day for awhile, at the retreat of the waters, they meet as if by mutual
agreement. Now you see them dressing their plumage, DOW partially expanding
their wings to the sun; some lay themselves comfortably down on the sand, while
others, supported by one foot, stand side by side. The waters again advance,
and the Gulls all move off in search of food. At length the time has arrived;
small parties of a few pairs fly towards the desert isles. Some remain in the
nearest to prepare their nests, the rest proceed, until each pair has found a
suitable retreat, and before a fortnight has elapsed, incubation has commenced.
The nest of this species is usually placed on the bare rock of some low
island, sometimes beneath a projecting shelf, sometimes in a wide fissure. In
Labrador it is formed of moss and sea-weeds carefully arranged, and has a
diameter of about two feet, being raised on the edges to the height of five or
six inches, but seldom more than two inches thick in the centre, where feathers,
dry grass, and other materials are added. The eggs are three, and in no
instance have I found more. They are two inches and seven-eighths in length, by
two inches and one-eighth in breadth, broadly ovate, rough but not granulated,
of a pale earthy greenish-grey colour, irregularly blotched and spotted with
brownish-black, dark umber, and dull purple. Like those of most other Gulls,
they afford good eating. This species lays from the middle of May to that of
June, and raises only one brood in the season. The birds never leave their eggs
for any length of time, until the young make their appearance. Both sexes
incubate, the sitting bird being supplied with food by the other. During the
first week, the young are fed by having their supplies disgorged into their
bill, but when they have attained some size, the food is dropped beside or
before them. When they are approached by man, they walk with considerable speed
towards some hiding place, or to the nearest projecting ledge, beneath which
they squat. When five or six weeks old, they take to the water, to ensure their
escape, and swim with great buoyancy. If caught, they cry in the manner of
their parents. On the 18th of June, several small ones were procured and placed
on the deck of the Ripley, where they walked with ease and picked up the food
thrown to them. As soon as one was about to swallow its portion, another would
run up, seize it, tug at it, and if stronger, carry it off and devour it. On
the 23d of that month, two individuals, several weeks old, and partly fledged,
were also brought on board. Their notes, although feeble, perfectly resembled
those of their parents. They ate greedily of every thing that was offered to
them. When fatigued they sat with their tarsi placed on the ground and extended
forward, in the manner of all the Herons, which gave them a very ludicrous
appearance. Ere a month had elapsed, they appeared to have formed a complete
acquaintance with the cook and several of the sailors, had become quite fat, and
conducted themselves much like Vultures, for if a dead Duck, or even a Gull of
their own species, were thrown to them, they would tear it in pieces, drink the
blood, and swallow the flesh in large morsels, each trying to rob the others of
what they had torn from the carcass. They never drank water, but not
unfrequently washed the blood and filth from their bills, by immersing them and
then shaking the head violently. These birds were fed until they were nearly
able to fly. Now and then, the sailors would throw them overboard while we were
in harbour. This seemed to gratify the birds as well as the sailors, for they
would swim about, wash themselves, and dress their plumage, after which they
would make for the sides, and would be taken on board. During a violent gale,
one night, while we were at anchor in the harbour of Bras d'Or, our bark rolled
heavily, and one of our pets went over the side and swam to the shore, where,
after considerable search next day, it was found shivering by the lee of a rock.
On being brought to its brothers, it was pleasant to see their mutual
congratulations, which were extremely animated. Before we left the coast, they
would sometimes fly of their own accord into the water to bathe, but could not
return to the deck without assistance, although they endeavoured to do so. I
had become much attached to them, and now and then thought they looked highly
interesting, as they lay panting on their sides on the deck, although the
thermometer did not rise above 55 degrees. Their enmity to my son's pointer was
quite remarkable, and as that animal was of a gentle and kindly disposition,
they would tease him, bite him, and drive him fairly from the deck into the
cabin. A few days after leaving St. George's Bay in Newfoundland, we were
assailed by a violent gale, and obliged to lie-to. Next day one of the Gulls
was washed overboard. It tried to reach the vessel again, but in vain; the gale
continued; the sailors told me the bird was swimming towards the shore, which
was not so far off as we could have wished, and which it probably reached in
safety. The other was given to my friend Lieutenant GREEN of the United States
army, at Eastport in Maine. In one of his letters to me the following winter,
he said that the young Larus marinus was quite a pet in the garrison, and doing
very well, but that no perceptible change had taken place in its plumage.
On referring to my journal again, I find that while we were at anchor at
the head of St. George's Bay, the sailors caught many codlings, of which each of
our young Gulls swallowed daily two, measuring from eight to ten inches in
length. It was curious to see them after such a meal: the form of the fish
could be traced along the neck, which for awhile they were obliged to keep
stretched out; they gaped and were evidently suffering; yet they would not throw
tip the fish. About the time the young of this species are nearly able to fly,
they are killed in considerable numbers on their breeding-grounds, skinned and
salted for the settlers and resident fishermen of Labrador and Newfoundland, at
which latter place I saw piles of them. When they are able to shift for
themselves, their parents completely abandon them, and old and young go
separately in search of food.
The flight of the Great Black-backed Gull is firm, steady, at times
elegant, rather swift, and long protracted. While travelling, it usually flies
at the height of fifty or sixty yards, and proceeds in a direct course, with
easy, regulated flappings. Should the weather prove tempestuous, this Gull,
like most others, skims over the surface of the waters or the land within a few
yards or even feet, meeting the gale, but not yielding to it, and forcing its
way against the strongest wind. In calm weather and sunshine, at all seasons of
the year, it is fond of soaring to a great height, where it flies about
leisurely and with considerable elegance for half an hour or so, in the manner
of Eagles, Vultures, and Ravens. Now and then, while pursuing a bird of its own
species, or trying to escape from an enemy, it passes through the air with rapid
boundings, which, however, do not continue long, and as soon as they are over it
rises and slowly sails in circles. When man encroaches on its domains, it keeps
over him at a safe distance, not sailing so much as moving to either side with
continued flappings. To secure the fishes on which it more usually preys, it
sweeps downwards with velocity, and as it glides over the spot, picks up its
prey with its bill. If the fish be small, the Gull swallows it on wing, but if
large, it either alights on the water, or flies to the nearest shore to devour
it.
Although a comparatively silent bird for three-fourths of the year, the
Great Black-backed Gull becomes very noisy at the approach of the breeding
season, and continues so until the young are well fledged, after which it
resumes its silence. Its common notes, when it is interrupted or surprised,
sound like cack, cack, cack. While courting, they are softer and more
lengthened, and resemble the syllables cawah, which are often repeated as it
sails in circles or otherwise, within view of its mate or its place of abode.
This species walks well, moving firmly and with an air of importance. On
the water it swims lightly but slowly, and may soon be overtaken by a boat. It
has no power of diving although at times, when searching for food along the
shores, it will enter the water on seeing a crab or a lobster, to seize it, in
which it at times succeeds. I saw one at Labrador plunge after a large crab in
about two feet of water, when, after a tug, it hauled it ashore, where it
devoured it in my sight. I watched its movements with a glass, and could easily
observe how it tore the crab to pieces, swallowed its body, leaving the shell
and the claws, after which it flew off to its young and disgorged before them.
It is extremely voracious, and devours all sorts of food excepting
vegetables, even the most putrid carrion, but prefers fresh fish, young birds,
or small quadrupeds, whenever they can be procured. It sucks the eggs of every
bird it can find, thus destroying great numbers of them, as well as the parents,
if weak or helpless. I have frequently seen these Gulls attack a flock of young
Ducks while swimming beside their mother, when the latter, if small, would have
to take to wing, and the former would all dive, but were often caught on rising
to the surface, unless they happened to be among rushes. The Eider Duck is the
only one of the tribe that risks her life, on such occasions, to save that of
her young. She will frequently rise from the water, as her brood disappear
beneath, and keep the Gull at bay, or harass it until her little ones are safe
under some shelving rocks, when she flies off in another direction, leaving the
enemy to digest his disappointment. But while the poor Duck is sitting on her
eggs in any open situation, the marauder assails her, and forces her off, when
he sucks the eggs in her very sight. Young Grouse are also the prey of this
Gull, which chases them over the moss-covered rocks, and devours them before
their parents. It follows the shoals of fishes for hours at a time, and usually
with great success. On the coast of Labrador, I frequently saw these birds
seize flounders on the edges of the shallows; they often attempted to swallow
them whole, but, finding this impracticable, removed to some rock, beat them,
and tore them to pieces. They appear to digest feathers, bones, and other hard
substances with ease, seldom disgorging their food, unless for the purpose of
feeding their young or mates, or when wounded and approached by man, or when
pursued by some bird of greater power. While at Boston in Massachusetts, one
cold winter morning, I saw one of these Gulls take up an eel, about fifteen or
eighteen inches in length, from a mud bank. The Gull rose with difficulty, and
after some trouble managed to gulp the head of the fish, and flew towards the
shore with it, when a White-headed Eagle made its appearance, and soon overtook
the Gull, which reluctantly gave up the eel, on which the Eagle glided towards
it, and, seizing it with its talons, before it reached the water, carried it
off.
This Gull is excessively shy and vigilant, so that even at Labrador we
found it difficult to procure it, nor did we succeed in obtaining more than
about a dozen old birds, and that only by stratagem. They watched our movements
with so much care as never to fly past a rock behind which one of the party
might be likely to lie concealed. None were shot near the nests when they were
sitting on their eggs, and only one female attempted to rescue her young, and
was shot as she accidentally flew within distance. The time to surprise them
was during violent gales, for then they flew close to the tops of the highest
rocks, where we took care to conceal ourselves for the purpose. When we
approached the rocky islets on which they bred, they left the place as soon as
they became aware of our intentions, cackled and barked loudly, and when we
returned, followed us at a distance more than a mile.
They begin to moult early in July. In the beginning of August the young
were seen searching for food by themselves, and even far apart. By the 12th of
that month they had all left Labrador. We saw them afterwards along the coast
of Newfoundland, and while crossing the Gulf of St. Lawrence, and found them
over the bays of Nova Scotia, as we proceeded southward. When old, their flesh
is tough and unfit for food. Their feathers are elastic, and good for pillows
and such purposes, but can rarely be procured in sufficient quantity.
The most remarkable circumstance relative to these birds is, that they
either associate with another species, giving rise to a hybrid brood, or that
when very old they lose the dark colour of the back, which is then of the same
tint as that of the Larus argentatus, or even lighter. This curious fact was
also remarked by the young gentlemen who accompanied me to Labrador; and
although it is impossible for me to clear up the doubts that may be naturally
entertained on this subject, whichever of the two suppositions is adopted, the
fact may yet be established and accounted for by persons who may have better
opportunities of watching them and studying their habits. No individuals of
Larus argentatus were, to my knowledge, seen on that coast during the three
months which I passed there, and the fishermen told us that the "saddle-backs
were the only large Gulls that ever breed there."
This bird must be of extraordinary longevity, as I have seen one that was
kept in a state of captivity more than thirty years. The following very
interesting account of the habits of a partially domesticated individual I owe
to my esteemed and learned friend Dr. NEILL of Edinburgh.
"In the course of the summer of 1818, a "big scoria" was brought to me by a
Newhaven fisher-boy, who mentioned that it had been picked up at sea, about the
mouth of the Frith of Forth. The bird was not then fully fledged: it was quite
uninjured: it quickly learned to feed on potatoes and kitchen refuse, along
with some Ducks; and it soon became more familiar than they, often peeping in at
the kitchen window in hopes of getting a bit of fat meat, which it relished
highly. It used to follow my servant PEGGY OLIVER about the doors, expanding
its wings and vociferating for food. After two moults I was agreeably surprised
to find it assuming the dark plumage of the back, and the shape and colour of
the bill of the Larus marinus, or Great Black-backed Gull; for I had hitherto
regarded it as merely a large specimen of the Lesser Black-backed (L. fuscus),
a pair of which I then possessed, but which had never allowed the new comer to
associate with them. The bird being perfectly tame, we did not take the
precaution of keeping the quills of one wing cut short, so as to prevent flight;
indeed, as it was often praised as a remarkably large and noble looking Sea-maw,
we did not like to disfigure it. In the winter of 1821-2, it got a companion in
a cock-heron, which had been wounded in Coldinghame Muir, brought to Edinburgh
alive, and kept for some weeks in a cellar in the old college, and then
presented to me by the late Mr. JOHN WILSON, the janitor,--a person remarkably
distinguished for his attachment to natural history pursuits. This Heron we
succeeded in taming completely, and it still (1835) remains with me, having the
whole garden to range in, the trees to roost upon, and access to the loch at
pleasure, the loch being the boundary of my garden. Some time in the spring of
1822, the large Gull was missing; and we ascertained (in some way that has now
escaped my memory) that it had not been stolen, nor killed, as we at first
supposed, but had taken flight, passing northwards over the village, and had
probably therefore gone to sea. Of course I gave up all expectation of ever
hearing more of it. It was not without surprise, therefore, that on going home
one day in the end of October of that year, I heard my servant calling out with
great exultation, "Sir, Big Gull is come back!" I accordingly found him walking
about in his old haunts in the garden, in company with, and recognising (as I am
firmly persuaded) his old friend the Heron. He disappeared in the evening, and
returned in the morning, for several days; when PEGGY OLIVER thought it best to
secure him. He evidently did not like confinement, and it was concerted that he
should be allowed his liberty, although he ran much risk of being shot on the
mill-pond by youthful sportsmen from Edinburgh. After this temporary captivity,
he was more cautious and shy than formerly; but still he made almost daily
visits to the garden, and picked up herrings or other food laid down for him.
In the beginning of March 1823 his visits ceased; and we saw no more of him till
late in the autumn of that year. These winter visits to Canonmills, and summer
excursions to the unknown breeding-place, were continued for years with great
uniformity: only I remarked that after the Gull lost his protectress, who died
in 1826 , he became more distant in his manners. In my note-book, under date
of 26th October, 1829, I find this entry: 'Old PEGGY's Great Black-backed Gull
arrived at the pond this morning, the seventh (or eighth) winter he has
regularly returned. He had a scorie with him, which was soon shot on the loch,
by some cockney sportsman.' The young bird, doubtless one of his offspring, had
its wing shattered, and continued alive in the middle of the pond, occasionally
screaming piteously, for two or three days, till relieved by death. The old
Gull immediately abandoned the place for that winter, as if reproaching us for
cruelty. By next autumn, however, he seemed to have forgotten the injury; for,
according to my record, '30th October, 1830. The Great Black-backed Gull once
more arrived at Canonmills garden.' The periods of arrival, residence, and
departure were nearly similar in the following year. But in 1832, not only
October, but the months of November and December passed away without Gull's
making his appearance, and I of course despaired of again seeing him. He did,
however, at length arrive. The following is the entry in my common-place book:
'Sunday, 6th January, 1833. This day the Great Black-back returned to the
mill-pond, for (I think) the eleventh season. He used to re-appear in October
in former years, and I concluded him dead or shot. He recognised my voice, and
hovered over my head.' He disappeared early in March as usual, and reappeared
at Canonmills on 23d December, 1833, being a fortnight earlier than the date of
his arrival in the preceding season, but six weeks later than the original
period of reappearance. He left in the beginning of March as usual, and I find
from my notes that he 'reappeared on 30th December, 1834, for the season, first
hovering around and then alighting on the pond as in former years.' The latest
entry is, '11th March, 1835. The Black-backed Gull was here yesterday, but has
not been seen to-day; nor do I expect to see him till November.'
"This Gull has often attracted the attention of persons passing the village
of Canonmills, by reason of its sweeping along so low or near the ground, and on
account of the wide expanse of wing which it thus displays. It is well known to
the boys of the village as "NEILL's Gull," and has, I am aware, owed its safety
more than once to their interference, in informing passing sportsmen of its
history. When it first arrives in the autumn, it is in the regular habit of
making many circular sweeps around the pond and garden, at a considerable
elevation, as if reconnoitring; it then gradually lowers its flight, and gently
alights about the centre of the pond. Upon the gardener's mounting the
garden-wall with a fish in his hand, the Gull moves towards the overhanging
spray of some large willow-trees, so as to catch what may be thrown to him,
before it sinks in the water. There can be no doubt whatever of the identity of
the bird. Indeed, he unequivocally shews that he recognises my voice when I
call aloud 'Gull, Gull;' for whether he be on wing or afloat, he immediately
approaches me.
"A few pairs of the Great Black-backed Gull breed at the Bass Rock yearly,
and it seems highly probable that my specimen had originally been hatched there.
If I may be allowed a conjecture, I would suppose that, after attaining
maturity, he for some years resorted to the same spot for the purpose of
breeding; but that of late years, having lost his mate or encountered some other
disaster, he has extended his migration for that purpose to some very distant
locality, which has rendered his return to winter quarters six weeks later than
formerly."

globular dilatation 1 1/2 inches in diameter.
The trachea is 12 inches long; at the top 7 1/2 twelfths wide gradually
contracting to 4 1/2 twelfths, considerably flattened, its rings slightly
ossified, 148 in number, of moderate breadth, very thin, contracted in the
middle line before and behind; the last half ring is large, moderately arched.
In this, as in all the other Gulls, there is a pair of slender muscles arising
from the sides of the thyroid bone in front, separating from the trachea,
attaching themselves to the subcutaneous cellular tissue, and inserted into the
furcula. Another pair arise from the same bone in front, spreading over the
whole anterior surface of the trachea, then become collected on the sides, send
off a slip to the costal process of the sternum, and continue narrow, to be
inserted into the last arched half-ring of the trachea; thus forming what is
called a single pair of inferior laryngeal muscles. Bronchi wide, each with 28
half rings. "PEGGY OLIVER was remarkable for the zeal and taste she displayed in the domesticating of uncommon animals, as well as in the culture of plants: her expertness in the latter department is noticed and praised by Mr. LOUDON in his Gardener's Magazine. Her funeral was attended by some of the most distinguished naturalists here, and, among others, by your friend Dr. MACCULLOCH of Pictou, who happened to be in Edinburgh at the time, and whose friendship I have also the happiness to enjoy."
