BLACK-HEADED., OR LAUGHING GULL. [Laughing Gull.] |
Genus | LARUS ATRICILLA, Linn. [Larus atricilla.] |
Much confusion appears to exist among authors regarding our Laughing Gull,
and this, in my humble opinion, simply because not one of them has studied it,
in its native haunts, and at all seasons, since the period when it was briefly
characterized by our great master LINNAEUS, who, after all that has been said
against him, has not yet had his equal. ALEXANDER WILSON, who, it seems, knew
something of the habits of this bird, thought it however identical with the
Larus ridibundus of Europe, as is shewn by the synonymes which he has given.
Others, who only examined some dried skins, without knowing so much as the day
or even the year in which they had been shot, or their sex, or whether the
feathers before them had once belonged to a bird that was breeding, or barren,
when it was procured, described its remains perhaps well enough for their own
purpose, but certainly not with all the accuracy which is necessary to establish
once and for ever a distinct species of bird. Others, not at all aware that
most Gulls, and the present species in particular, assume, in the season of
pairing, and in a portion of the breeding time, beautiful rosy tints in certain
parts of their plumage, which at other periods are pure white, have thought that
differences of this sort, joined to those of the differently-sized white spots
observable in particular specimens, and not corresponding with the like markings
in other birds of the same size and form, more or less observable at different
periods on the tips of the quills, were quite sufficient to prove that the young
bird, and the breeding bird, and the barren bird, of one and the same species,
differed specifically from the old bird, or the winter-plumage bird. But,
reader, let us come to the point at once.
At the approach of the breeding season, or, as I like best to term it, the
love season, this species becomes first hooded, and the white feathers of its
breast, and those of the lower surface of its wings, assume a rich blush of
roseate tint. If the birds procured at that time are several years old and
perfect in their powers of reproduction, which is easily ascertained on the
spot, their primary quills shew little or no white at their extremities, and
their hood descends about three quarters of an inch lower on the throat than on
the hind part of the head, provided the bird be a male. But should they be
barren birds, the hood will be wanting, that portion of their plumage remaining
as during winter, and although the primaries will be black, or nearly so, each
of them will be broadly tipped, or marked at the end, with a white spot, which
in some instances will be found to be fully half an inch in size; yet the tail
of these birds, as if to prove that they are adults, is as purely white to its
extreme tip, as in those that are breeding; but neither the breast, nor the
under wing-coverts, will exhibit the rosy tint of one in the full perfection of
its powers.
The males of all the Gulls with which I am acquainted, are larger than the
females; and this difference of size is observable in the young birds even
before they are fully fledged. In all of these, however, putting aside their
sex, I have found great differences of size to exist, sometimes as much as two
inches in length, with proportional differences in the bills, tarsi, and toes;
and this, in specimens procured from one flock of these Gulls at a single
discharge of the gun, and at different seasons of the year. The colour of their
bills too is far from being always alike, being brownish-red in some, purplish
or of a rich and deep carmine in others. As to the white spots on the
extremities of the primary quills of birds of this family, I would have you,
reader, never to consider them as affording essential characters. Nay, if you
neglect them altogether, you will save yourself much trouble, as they will only
mislead you by their interminable changes, and you may see that the spots on one
wing are sometimes different in size and number from those on the other wing of
the same specimen. If all this be correct, as I assure you it must be, being
the result of numberless observations made in the course of many years, in the
very places of resort of our different Gulls, will you not agree with me,
reader, that the difficulty of distinguishing two very nearly allied species
must be almost insuperable when one has nothing better than a few dried skins
for objects of observation and comparison?
The Black-headed Gull may be said to be a constant resident along the
southern coast of the United States, from South Carolina to the Sabine river;
and I have found it abundant over all that extent both in winter and in summer,
but more especially on the shores and keys of the Floridas, where I found it
breeding, as well as on some islands in the Bay of Galveston in Texas. A very
great number of these birds however remove, at the approach of spring, towards
the Middle and Eastern Districts, along the shores of which they breed in
considerable numbers, particularly on those of New Jersey and Long Island, as
well as on several islands in the Sound. They constantly evince a dislike to
rocky shores, and therefore are seldom seen beyond Massachusetts, in which State
indeed they are exceedingly rare.
None were observed by any members of my party on the Magdalene Islands, or
on the coasts of Labrador or Newfoundland. I never met with any of them on the
Mississippi above New Orleans, although they are plentiful in that neighbourhood
during winter, and until the breeding season commences; and I think that this
species never travels beyond the influence of the tide-waters of any stream.
WILSON, in speaking of it, says that it is seen on the newly ploughed fields,
and around the houses of the farmers of New Jersey; but the habit of visiting
ploughed grounds I have not observed in any one of the American Gulls, although
I have frequently noticed it in some of the European species, particularly Larus
canus, L. ridibundus, and L. argentatus.
At all periods of the year, the Black-headed Gulls keep in flocks formed of
many families; and in the breeding season, or even as soon as their courtships
have commenced, they assemble by hundreds of pairs, or even by thousands. At
this time they are so clamorous as to stun your ear with their laughing-like
cries, though at other seasons they are generally silent, unless when suddenly
alarmed, or when chased by the Jager. Their loves are conducted with extreme
pomposity: they strut and bow to the females, throwing their head backwards,
like all other Gulls, although in a less degree and with a less curious motion
than Cormorants. You see them first stretching their heads forwards; then, with
open bill, vibrating tongue, and eyes all glowing, they emit their loud laughing
notes, which, in a general sense, resemble those of many other species, though
they are not precisely similar to those of any. But before I proceed with my
account of their manners, I will give you the result of some curious
observations which I made on them in Florida.
Previously to my visit to that interesting peninsula, I had not
unfrequently noticed indications of strong amatory propensities in several
species of Gulls, but never to the extent exhibited by the present species, many
of which I saw copulating in the latter part of autumn and in winter, fully
three months before the usual time of depositing their eggs in that country.
Similar observations were made on Larus argentatus, on the coast of Maine, and
on Larus marinus, in the Bay of Fundy. Nay, even in Europe I have seen this
extraordinary tendency to reproduce out of season, as it were. On some such
occasions, when I was at St. Augustine, in the month of December, I have
observed four or five males of the present species paying their addresses to one
female, who received their courtesies with evident welcome. Yet the females in
that country did not deposit eggs until the 20th day of April. The most
surprising fact of all was, that, although these birds were paired, and
copulated regularly, by the 1st of February, not one had acquired the spring or
summer plumage, or the dark coloured hood, or the rosy tint of the breast, nor
lost the white spots on the tips of their primary quills. This change, however,
was apparent by the 5th of March, became daily stronger, and was perfected by
the 15th of that month. A few exceptions occurred among the numbers procured at
these periods, but the generality of the birds were as above described.
Whilst at Great Egg Harbour, in May 1829, shortly after my return from
England, I found this species breeding in great numbers on the margins of a vast
salt marsh, bordering the sea-shore, though separated from the Atlantic by a
long and narrow island. About sunrise every morning, an immense number of these
birds would rise in the air, as if by common consent, and wing their way across
the land, probably intent on reaching the lower shores of the Delaware river, or
indeed farther towards the head waters of Chesapeake Bay. They formed
themselves into long straggling lines, following each other singly, at the
distance of a few yards. About an hour before sunset, the same birds were seen
returning in an extended front, now all silent, although in the morning their
cries were incessant, and lasted until they were out of sight. On arriving at
the breeding-ground, they immediately settled upon their nests. On a few
occasions, when it rained and blew hard, the numbers that left the nests were
comparatively few, and those, as I thought, mostly males. Instead of travelling
high, as they were wont to do in fair and calm weather, they skimmed closely
over the land, contending with the wind with surprising pertinacity, and
successfully too. At such times they were also quite silent. I now and then
observed some of them whilst on wing, and at a considerable height, suddenly
check their course, as if to examine some object below; but on none of these
occasions did I see one attempt to alight, for it soon resumed its wonted
course, and rejoined its companions.
Now, reader, though I am growing old, I yet feel desirous of acquiring
knowledge regarding the habits of our birds, and should much like to learn from
you the reasons why these Gulls went off in lines from their breeding-grounds,
and returned in an extended front? Was it, in the latter case, because they
were afraid of passing their nests unknowingly; or, in the former, under the
necessity of following an experienced leader, who, under the stimulus of an
empty maw, readily undertook the office, but who, like many other bon-vivants,
became in the evening too dull to be of use to his companions?
This species breeds, according to the latitude, from the 1st of March to
the middle of June; and I have thought that on the Tortuga Keys, it produced two
broods each season. In New Jersey, and farther to the eastward, the nest
resembles that of the Ring-billed Gull, or Common American Gull, Larus
zonorhynchus, being formed of dried sea-weeds and land plants, two and sometimes
three inches high, with a regular rounded cavity, from four and a half to five
inches in diameter, and an inch and a half in depth. This cavity is formed of
finer grasses, placed in a pretty regular circular form. I once found a nest
formed as it were of two; that is to say, two pairs had formed a nest of nearly
double the ordinary size, and the two birds sat close to each other during rainy
weather, but separately, each on its own three eggs. I observed that the males,
as well as the females, thus concerned in this new sort of partnership, evinced
as much mutual fondness as if they were brothers. On the Tortugas, where these
Gulls also breed in abundance, I found their eggs deposited in slight hollows
scooped in the sand. Whilst at Galveston, in Texas, I found their nests
somewhat less bulky than in the Jerseys, which proved to me how much birds are
guided in these matters by differences in atmospheric temperature and locality.
I never found more than three eggs in a nest. Their average length is two
inches and half an eighth, their greatest breadth a trifle more than an inch and
a half. They vary somewhat in their general tint, but are usually of a light
earthy olive, blotched and spotted with dull reddish-brown and some black, the
markings rather more abundant towards the larger end. As an article of food,
they are excellent. These Gulls are extremely anxious about their eggs, as well
as their young, which are apt to wander away from the nest while yet quite
small. They are able to fly at the end of six weeks, and soon after this are
abandoned by their parents, when the old and young birds keep apart in flocks
until the following spring, when, I think, the latter nearly attain the plumage
of their parents, though they are still smaller, and have the terminal band on
the tail.
The Black-headed Gull frequently associates with the Razor-billed
Shearwater, Rhynchops nigra, in winter; and I can safely say that I have seen
more than a thousand of each kind alight on the same points of estuaries and
mouths of rivers; the Gulls standing or sitting by themselves, at no great
distance from the Razor-bills. Now and then they would all suddenly rise on
wing as if frightened, perform a few evolutions in the air, and again settle on
the very same spot, still, however, keeping separate. While thus in the company
of the Razor-bills, the Gulls are with great difficulty approached, the former
being exceedingly wary, and almost always rising when a person draws near, the
Gulls immediately following them, and the two great flocks making off to some
distant point, generally not very accessible. If taken up on being wounded,
these Gulls are apt to bite severely. If, on being shot at, they fall on the
water, they swim fast and lightly, their companions all the while soaring above,
and plunging towards them, as if intent on rescuing them. This great sympathy
often proves fatal to them, for, if the gunner is inclined, he may shoot them
down without any difficulty, and the more he kills the more his chances are
increased.
On the 10th of May, 1832, it was my good fortune to be snugly on board the
"Lady of the Green Mantle," or, in other words, the fine revenue cutter Marion.
The Gulls that laughed whilst our anchors were swiftly descending towards the
marvellous productions of the deep, soon had occasion to be sorrowful enough.
As they were in great numbers, officers and men, as well as the American
woodsman, gazing upon them from the high decks of the gallant bark, had ample
opportunities of observing their motions. They were all busily engaged on wing,
hovering here and there around the Brown Pelicans, intent on watching their
plunges into the water, and all clamorously teasing their best benefactors. As
with broadly extended pouch and lower mandible, the Pelican went down headlong,
so gracefully followed the gay rosy-breasted Gull, which, on the brown bird's
emerging, alighted nimbly on its very head, and with a gentle stoop instantly
snatched from the mouth of its purveyor the glittering fry that moment
entrapped!
Is this not quite strange, reader? Aye, truly it is. The sight of these
manoeuvres rendered me almost frantic with delight. At times, several Gulls
would attempt to alight on the head of the same Pelican, but finding this
impossible, they would at once sustain themselves around it, and snatch every
morsel that escaped from the pouch of the great bird. So very dexterous were
some of the Gulls at this sport, that I have seen them actually catch a little
fish as it leaped from the yet partially open bill of the Pelican. And now,
reader, I will conclude this long article with some fragments from my journals.
Tortugas, May 1832.--Whilst here, I often saw the Black-headed Gull of
WILSON, sucking the eggs of Sterna fuliginosa, and Sterna stolida. Our sailors
assured me that these Gulls also eat the young of these two species of Terns
when newly hatched.
Great Egg Harbour, May 1829.--Like all other Gulls, the Larus Atricilla
disgorges its food when attacked by a Lestris, or when wounded, or suddenly
surprised; but on all occasions of respite this Gull is apt to return to it, and
vulture-like to swallow it anew. It differs however from the larger species of
Gulls, by never, as far as I have observed, picking up bivalve shells, for the
purpose of letting them fall to break them, and afterwards feed on their
contents. On the ground they walk with considerable alertness, and not without
a certain degree of elegance, especially during the love season. Whilst
floating or swimming on the water, they are graceful in a high degree, and when
seen, as they oftentimes are, in groups of many pairs, rising with, or sinking
amidst the billows, which ever and anon break on the sandy shores of the coast,
their alternate appearance brings to the mind of the bystander ideas connected
with objects altogether different from the simple yet beautiful Laughing Gull.
April 1, 1837.--South-west pass of the Mississippi. L. Atricilla abundant
here at this season, as well as at New Orleans. Saw some floating on logs
during a heavy breeze. Not noisy yet, though they and L. zonorhynchus are in
full spring dress (the old birds).
Barataria Bay, April 1837.--This species is abundant, following the
porpoises, whilst the latter are fishing, and attending on them, as they do on
the Brown Pelicans, which I saw here tormented by these birds, as in the
Floridas. These Gulls follow the Brown Pelicans to their roosts, and along with
them sit on grounded logs, at some distance from the shores, to avoid the
attacks of racoons and other carnivorous animals.
Galveston Bay, April 26, 1837.--Black-headed Gulls are not unfrequently
seen hovering over the inner ponds of these islands, as if in search of food.
They are now all paired, and very noisy.
May 4.--I observed to-day that at the single cry of a Black-headed Gull,
all others within hearing at once came towards the caller, and this never failed
when any of them had found floating garbage on which to feed. These, as well as
all other Gulls, pat the water with their feet, their legs being partially
extended, whilst assisting themselves with the bill to pick up any floating
food. At this time the whole group emit a more plaintive single note than
usual. They come not unfrequently within a few yards of our vessel at anchor,
and when the food thrown to them is exhausted, they separate, and at once renew
their repeated cries. I observed that the few immature birds among the old
ones, were quite silent even when in the company of the adults. When the young
are nearly able to fly, they are by no means bad eating.

beautiful light rosy tint. The back and wings are greyish-blue, with a very
slight tinge of purple, excepting a large terminal portion of the secondaries,
and the tips of the primaries, which are white. The first primary is black,
with a tinge of grey on the inner web at the base; the second and third similar,
with the grey more extended; on the fourth it extends over two-thirds; the fifth
is black only for an inch and a half; and on the sixth the black is reduced to
two spots near the end; the other parts and the remaining primaries of the same
general colour as the back.

The female is precisely similar to the male, but considerably smaller.
In winter the head is white, the feathers on its upper part and on the nape
more or less brownish-grey in their concealed part, that colour appearing in
slight patches here and there, and especially along the posterior margin of the
part that is coloured in summer, as well as on a small space before the eye.
The rosy tint of the breast disappears after the breeding season. In other
respects the plumage is as in summer.

patch before the eye, two slight bands on the eyelids, and the throat,
greyish-white; the lower part of the neck brownish-grey, the rest of the lower
parts greyish-white, the sides darker, the axillars ash-grey, the lower surface
of the wing dusky-grey.
In an adult male the tongue is 1 1/4 inches long, slender, tapering,
emarginate at the base, with minute papillae, the tip horny along the back. The

in all birds. In the stomach remains of fishes. Intestines 1 foot 9 1/2 inches
long, its general diameter 1/4 inch. Rectum 1 1/2 inches; coeca extremely
small, 2 1/2 twelfths long, 1/2 twelfth in diameter.
