“Very well, then" said Lucien, agreeing to the request.
“I shall tell you all I know of the swans; and, indeed, that is not
much, as the natural history of these birds in their wild state is but
little understood. On account of their shy habits, there is not much
opportunity of observing them; and as they annually migrate and breed in
those desolate regions within the Arctic circle, where civilized men do
not live, but little information has been collected about them. Some of
the species, however, breed in the temperate zones, and the habits of
these are better known.
“For a long time it was fancied there was but one species
of swan. It is now known that there are several, distinguished from each
other in form, colour, voice, and habits. "White as a swan" is a simile
as old, perhaps; as language itself. This, I fancy, would sound
strangely to the ears of a native Australian, who is accustomed to look
upon swans as being of the very opposite colour, for the black swan is a
native of that country.
According to the naturalist Brehm, who has given much
attention to this subject, there are four distinct species of swans in
Europe. They are all white, though some of the species have a reddish
orange tinge about the head and neck. Two of them are £ gibbous/ that
is, with a knob or protuberance upon the upper part of the bill. One of
these Brelun terms the 'white-headed gibbous swan’ (Cygnus gibbus). The
other is the 'yellowheaded' and this last also is known as
the mute or tame swan, because it is that species most commonly seen in
a tame state upon the ornamental lakes and ponds of England. The other
two European species Brehm has designated 'singing swans' as both of
them utter a note that may be heard to a considerable distance.
"The black swan of Australia (C. niger) has been
naturalized in Europe, and breeds freely in England, where, from its
great size and peculiar markings, it is one of the most ornamental of
water-fowls. It is, moreover, a great tyrant, and will not permit other
birds to approach its haunt, but drives them off, striking them
furiously with its strong broad wings.
“Until a late period the swans of America were supposed
to be all of one kind. This is not the case. There are now known to be
three distinct species inhabiting the fur countries, and migrating
annually to the South. That which is best known is the ‘whistler,’ or
‘hooper’ (C. Americaniis), because it is the species that abounds in the
old States upon the Atlantic, and was therefore more observed by
naturalists. It is believed to be identical with one of the European
‘singing’ swans (C. ferus), but this is not certain; and for my part, I
believe they are different, as the eggs of the American swan are
greenish, while those of its European congener are brownish, with white
blotches.
“The 'hooper’ is four and a half feet in length, though
there are males still larger, some of them measuring five feet. Its
colour is white, except upon the head and back part of the neck, where
there is a coppery tinge. The bill and feet are black. From the angle of
the mouth to the eye there is a small naked 6 cere/ of a bright yellow
colour. These swans, like others of the genus, do not care much for the
salt water. They are rarely seen upon the sea, except near its shores,
where they may find the aquatic plants upon which they feed. Nor do they
go out upon the large lakes. When found upon these, it is generally
close in to the land. This is accounted for by the fact that the swans
do not dive for their food, but stretch down for it with their long
necks, which Nature has peculiarly adapted to this very purpose. Their
favourite food consists of the roots of aquatic plants,, which are often
farinaceous. As these grow best in the shallow small lakes and along the
margins of rivers, such places are the usual resort of the swans.
Although their diet is a vegetable one, it is not exclusively so, as
they will eat frogs, worms, and small fish. Unlike the ducks and geese,
they rarely feed upon land, but while floating upon the surface of the
water. They walk but awkwardly on land, and are at home only on water or
in the air. In the air they are quite at home, and fly so swiftly that
it is no easy matter to shoot them, especially when going before the
wind. At such times they are supposed to fly at the rate of one hundred
miles an hour. When moulting, and unable to rise into the air, it is no
easy matter to follow them even with a canoe. By means of their broad
feet and strong wings, they can flutter so quickly over the water, now
and then diving, that the hunter cannot overtake them in his boat, but
is obliged to use his gun in the pursuit.
“The hoopers are migratory,—that is, they pass to the
north every spring, and southward again in the autumn. Why they make
these annual migrations, remains one of the mysteries of nature. Some
believe they migrate to the north, because they there find those
desolate uninhabited regions where they can bring forth their young in
security. But this explanation cannot be the true one, as there are also
uninhabited regions in the south, even under the equator, where they may
be equally free from the presence of man. Another explanation might be
offered. In hot and tropical countries most of the small lakes and
swamps, where these birds love to dwell, dry up during the summer
months: hence the necessity of a migration to colder and moister
regions. But this would only hold good of the wading and water birds; it
would not account for the migration of the many other birds of passage.
“A better explanation may be this: The north and the cold
zones are the natural habitat of most migratory birds. It is there that
they bring forth their young, and there they are at home. In tropical
regions they are only sojourners for a season, forced thither, some of
them, by a cold which they do not relish; but others, such as the water
fowl, by the frost, which, binding up the lakes, rivers, and swamps,
hinders them from procuring their food. They are thus compelled to make
an annual migration to the open waters of the South, but as soon as the
ice has given way before the genial breath of spring, they all return
rejoicing to their favourite home in the North, when their season of
love commences.
“The 'hoopers' follow this general law, and migrate to
the northward every spring. They breed upon islets in the numerous lakes
that stud the whole northern part of the American continent. Eminences
in swamps are also chosen for breeding places, and the ends of
promontories that jut out into the water. The spot selected is always
such that the swan, when seated upon her nest, can have a view of the
surrounding country, and detect any enemy long before it can approach
her. The top of the dome-shaped dwellings of the musk-rat, or musquash
(Fiber zibetkicus), is often selected by the swan for her nest. These
curious little houses are usually in the midst of impenetrable swamps:
they are only occupied by their builders during the winter; and as they
are deserted by them in early spidng, they are therefore quite at the
service of the swan for the balance of the season. The bird makes a
large cavity in the top, and lines it with such reeds and grass as may
be found near the spot.
“The hooper lays from six to eight eggs, and sits upon
them for a period of six weeks, when the cygnets come forth covered with
a thick down of a bluish-grey colour. While sitting upon her eggs, the
swan is exceedingly watchful and shy. She ‘faces’ towards the point
whence she most apprehends danger. When the weather is severe, and the
wind cold and keen, she changes into that position which is most
comfortable. If her nest be upon a promontory instead of an island, she
usually sits with her head to the land, as she feels secure that no
enemy will reach her from the waterside. From the land she has not only
man to ‘look out’ for, but the wolverene (Gulo luscus), the lynx (Felis
Canadensis), foxes, and wolves.
“The Indians often snare the swan upon her nest. Of
course the snare — a running noose made from the intestines of the
deer—is set in her absence. It is placed upon the side by which she
enters, as these birds enter and leave the nest upon opposite sides. The
snare must be arranged with great care, and with clean hands; and the
Indians always take the precaution to wash their hands before setting
it, else the swans, whose sense of smell is very acute, will perceive
the presence of danger, and will not only keep away for a time, but
sometimes desert the eggs altogether. There are many other birds that
have a similar habit.
“So much for the ‘hooper,’” continued Lucien; “now for
the ‘trumpeter.' This is the largest of the American swans, being found
to measure seventy inches in length. Its specific name ‘trumpeter’ (C.
buccinator) is given to it on account of its note, which resembles the
sound of a French horn, or trumpet, played at a distance. The bird is
white, with black bill and feet, and has also a reddish orange or copper
tinge upon the1 crown and neck; but it wants the yellow spot between the
split of the mandibles and the eye. It is easily distinguished from the
hooper, both by its louder note and larger body. Its habits, however,
are very similar, except that it seems to be more gregarious,—small
flocks of six or eight often appearing together, while the hooper is
seen only in pairs, and sometimes solitary. Another distinction is, that
the trumpeter arrives much earlier in its migrations to the North, being
the earliest bird that appears except the eagles. It breeds as far South
as latitude 61°, but most generally within the Arctic circle. Its nest
is constructed similarly to those of the hooper, but its. eggs are much
larger, one of them being a meal for a moderate eater, without bread or
any other addition. The trumpeter frequently arrives in the North before
the lakes or rivers are thawed. It is then obliged to find sustenance at
the rapids and waterfalls, where the Indians can approach under cover,
and many are shot at such times by these people. At all other times, as
you, Francis, have observed, it is a bird most difficult of approach;
and the Indian hunters only attempt it when they have a long-range gun
loaded with ball.
"The third species of American swans is that known as
Bewick’s swan (C. Bewickii) called after the naturalist of that name. It
is the smallest of the three, rarely measuring over fifty-two inches in
length,' and weighing only fourteen pounds, while the hooper is over
twenty pounds in weight, and the trumpeter is often obtained of the
enormous weight of thirty:
“Bewick’s swan is also said to be identical with one of
Brehm’s singing swans. Its colour is almost similar to that of the
hooper, and the two are often mistaken for each other. The size and the
tail-feathers of all three of the American swans form a sufficiently
specific distinction. In the trumpeter these are twenty-four in number,
in the hooper twenty, while the small species has only eighteen.
“Of the three, the last-mentioned is the latest on its
annual journey, but it breeds farther North than either of the others.
Its nest is found upon the islands of the Arctic Sea; it is usually
built of peatmoss, and is of gigantic dimensions, being six feet long by
five in width, and nearly two feet high. In the top of this pile is the
nest itself, forming a large round cavity nearly two feet in diameter.
The eggs are of a brownish white, with clouds of darker tint.
“I have remarked,” continued Lucien, “a singularity in
the geographical distribution of these three species. Upon the Pacific
coast the smallest kind and the hooper only are met with, and the small
ones outnumber the others in the ratio of five to one. In the interior
parts of the continent only the hoopers and trumpeters appear; and the
trumpeters are by far the most numerous, while upon the eastern coasts
of America the hoopers are the sort best known.
“The swans are eagerly hunted both by the Indians and
white hunters. Their skins, with the quills and down, form a source of
profit to the natives of the fur countries, who dispose of them to the
Hudson’s Bay Company. In some years as many as ten thousand skins have
been exported, and sold at the rate of six or seven shillings each. Most
of the skins thus sold were those of the trumpeter swans, which are the
most numerous.
“Now,” said Lucien, in conclusion, “you know as much
about the swans as I do; so I shall drop the subject, and recommend to
all of you a piece of roast swan, which is now just done to a turn, and
which I doubt not will be found less dry than my lecture.” |
