Both summer and winter the great ice bear of the frozen north is
appropriately clothed in white. It is also distinguished from all other
bears by its long neck, slender pointed head, and the quantity of fur
on the soles of its feet. It is a circumpolar species, the limits of
whose range nearly everywhere coincide with the southern border of
the pack ice. The great majority live permanently on the ice, often
hundreds of miles from the nearest land.
During summer the polar bear rarely visits shore, but in winter
commonly extends its wanderings to the Arctic islands and the bordering
mainland coasts. In winter it ranges southward with the extension of
the ice pack. In spring, by an unexpectedly sudden retreat of the ice,
individual bears are often left south of their usual summer haunts,
sometimes being found swimming in the open sea far off the coast of
Labrador. Occasionally some of those which migrate southward with the
ice through Bering Straits fail to turn north early enough and are
stranded on islands in Bering Sea.
That a carnivore requiring so much food as the polar bear can maintain
itself on the frozen polar sea is one of the marvels of adaptation to
environment. The activity of these bears through the long black night
of the far north is proved by records of Arctic explorers, whose caches
have been destroyed and ships visited by them during that season. In
this period of privation they range far over land and ice in search of
food, and when in desperate need do not hesitate to attack men. I have
seen several Eskimos who had been seriously injured in such encounters,
and learned of other instances along the Arctic coast of Alaska in
which hunters had been killed on the sea ice in winter. During the
summer season of plenty, polar bears are mild and inoffensive, so far
as men are concerned. At that time they wander over the pack ice,
swimming in open leads, and, when hungry, killing a seal or young
walrus.
When spring opens, many polar bears are near the Arctic coast. At that
time the natives along the northeast coast of Siberia kill many of them
on the ice with dogs and short-hafted, long-bladed lances. The dogs
bring the bear to bay, and the hunter, watching his opportunity, runs
in and thrusts the lance through its heart.
During the cruise of the _Corwin_ we saw many of these bears on the
broken ice off Herald and Wrangel Islands. One large old male climbed
to the top of an uptilted ice-pan and, after looking about, lay down on
one side and, giving a push with one hind foot, slid down head foremost
30 or 40 feet, striking the water with a great splash. He then climbed
out and walked sedately away.
Another bear saw a seal basking on the ice by a large patch of open
water and, swimming across, suddenly raised himself half out of the
water to the edge of the ice, and by a blow of his paw crushed the
seal’s skull. He then climbed out and made a feast within 500 yards of
where the _Corwin_ was anchored to the ice pack.
Once while we were anchored in a dense fog several miles off the pack
a bear came swimming out to us, stopping every now and then to raise
its head high out of water to sniff the attractive odors from the ship.
Although strong and tireless swimmers, these bears lack the necessary
speed to capture their prey in the water.
The female retires in winter to a snug den among the hummocks on the
sea ice, where one or two naked cubs are born, which by the time the
ice begins to break up are ready to follow the mother. Until the cubs
are well grown the mother cares for and defends them with the most
reckless disregard for her own safety. On one occasion I saw a wounded
mother bear shield her cub, twice the size of a Newfoundland dog, when
bullets began to strike the water about them, by swimming straight away
with the cub safely sheltered between her forelegs.
The inaccessible character of so large a part of the home of the polar
bear will long preserve it from the extermination that is overtaking
some of the land bears.
=BLACK BEAR= (=Ursus americanus= and its subspecies)
Numerous species of black bears varying in size occur in North and
South America and in Asia. In North America a black bear, remarkably
uniform in general appearance, but representing various geographic
races and possibly species, is generally distributed throughout the
forested areas from the borders of the Arctic barrens, at the northern
limit of trees, south throughout the United States and down the wooded
Sierra Madre to Jalisco, Mexico, and from Newfoundland on the east to
Queen Charlotte Island on the west.
These bears are usually entirely black except for a brown patch
covering the muzzle and an occasional white spot on the breast. Their
weight is variable, the largest ones exceeding 500 pounds, but they
average much less.
The cinnamon bear, so common in the West and Northwest, long supposed
to be a distinct species, has proved to be merely a color phase of the
black bear--cinnamon cubs being born in the same litters with black
ones.
Since the days of primitive man and the great cave bear, the ways of
bears have had a fearsome interest to mankind. Childhood revels in the
delicious thrills of bear stories and dwells with wonder on the habit
bears have of standing upright like droll caricatures of man, on the
manlike tracks of their hind feet, and on their fondness for sweets and
other palatable food.
From the landing of the first colonists on our shores, hunters and
settlers have encountered black bears so frequently that these are
among the best-known large forest animals of the continent. During
winter they hibernate for months, seeking a hollow tree, a low cave,
the half shelter of fallen tree trunks and brush, or else digging a
den for themselves. The female chooses a specially snug den, where in
midwinter from one to four cubs are born. At birth the young, only 8 or
9 inches long, are practically naked and have their eyes closed. They
are so undeveloped at this time that it is more than a month before
their eyes open and more than two months before they can follow their
mother.
Although powerful beasts, black bears are so shy and timid that to
approach them requires the greatest skill on the part of a still
hunter. They only attack people when wounded or so cornered that they
must defend themselves or their young. To safeguard themselves from
danger they rely mainly on a fine sense of hearing and an exquisite
delicacy of smell. They have poor eyesight, and where a suspicious
object is seen, but no sound or scent can be noted, they sometimes rise
on their hind feet and look long and carefully before retreating.
To bears in the forest everything is game. They often spend the entire
day turning over stones to lick up the ants and other insects sheltered
there, and at night may visit settlers’ cabins and carry off pigs. They
raid the settlers’ cornfields for green corn and are passionately fond
of honey, robbing bee trees whenever possible. In season they delight
in wild cherries, blueberries, and other fruits, as well as beechnuts,
acorns, and pinyon nuts. They are mainly nocturnal, but in districts
where not much disturbed wander widely by day.
The success of black bears in caring for themselves is well
demonstrated by the numbers which still survive in the woods of Maine,
New York, and other long-settled States. Their harmlessness and their
exceeding interest to all render them worthy of careful protection.
They should be classed as game and thoroughly protected as such except
for certain open seasons. If this is done throughout the country, as
is now the case in certain States, the survival of one of our most
characteristic large wild animals will be assured.
