Polar Bear! |
Part of my initial series of shots |
"Bear!"
"Bear!”
Did I hear that right?
It is funny how many things can go through your head in a split second.
First, this isn’t where we are supposed to see bears. Polar Bears should be on the
pack ice way up north behind us. We already missed our chance.
Second, Kim’s probably mistaken. That's easy to do when you really want to see something. Kim is probably just seeing one of the shaggy
white Svalbard Reindeer, which we had just noticed moving up the cliff behind where the Puffins and Murres were
nesting.
Third, there’s an armed guard up on the cliff who would have alerted us
if there were a Polar Bear and we had heard nothing.
But, Kim was right.
I had my camera up and focused on the cliff, so I just shifted my eyes a fraction of an inch up.
Whoa!
A Polar Bear about 20 feet above us, looking at us.
Right above us!
Looking at us!
Right there!
Fortunately, I never missed a beat. I started taking photos without even thinking about it. I fired off a series of shots as the bear contemplated us and then turned and slowly sauntered out of sight. I was in the perfect position with the perfect camera at the perfect time.

Then, in the midst of all this excitement, Gerard swings around and
announces, “I am sorry folks, but we have to go.”
What?
He then went on to explain that he needed to take us back to the ship and get us off the Zodiac so that he could rush back to the shore to evacuate all the people who were walking around the
beach, dangerously close to a Polar Bear.
But, that wasn’t quite right.
There wasn't just a Polar Bear. There were two Polar Bears. As we sped away, we saw “our” Bear coming around the top of the cliff with his
mother.
That was the first view many got of the Bears.
As it turns out, no one else got the shots I got of that Bear. No one. Later Tom, our onboard Polar Bear expert asked to see my shots to see if the Bears were tagged.
I didn't get any close shots of the mother, but I did of the cub.

This is one of Scott's first shots of the Bears, |
Look at the tags in its ears |
Tom said that, if the cub were tagged, it was almost certain the mother was, too.
Otherwise, the people who tagged the Bear would not still be among the living. Makes sense.
The tags were quite small, looking more like earbuds than the big wildlife tags or collars we are used to seeing on Moose and Elk. The tags were most likely placed by the Norwegian Polar Institute, which has been conducting Polar Bear research since the 1960s, when animals were tagged and samples were taken from many Bears killed by hunters.
Today, research is done exclusively on live animals. Much of the field work is performed using helicopters, enabling researchers to access large numbers of animals over broad geographic areas. In an average year, approximately 100 bears are captured and measured.
More than 1,000 Bears have been marked since 1990, including 100 females fitted with satellite radio telemetry transmitters. When the Bears are first captured, they are tranquilized and blood and tissue samples are taken, along with a rudimentary tooth from any animal over one year old that is used to estimate age. Most of the tags do not contain telemetry equipment and are used just to ID bears upon subsequent captures.
The evacuation was amazingly fast and well-managed. And, it was a good
thing they did it, it didn’t take long for those two Bears to walk right across
the area where people had been standing before.
The G Adventures team was flabbergasted that the bears materialized out of seemingly nowhere.

Doesn't this ice bergie that we saw while watching the Polar Bears look like a Polar Bear? |
Later, Gerard told me that, even with all his arctic trips, that was as close as he had ever gotten to a Polar Bear.
Only 20 feet away! |

Bear photos I took in Kaktovik |
Good pictures, yes, as long as they
were only postcard size. At least, this
time I had a good camera set correctly.
What Else?
While we were photographing the bears, we floated past some Arctic Terns resting on icebergs. Our presence didn’t faze them.
Plus, I even got a picture of one carrying a tiny fish in its beak.
Plus, there were a fairly
large number of Common Eiders resting on the end of the moraine the bears
traversed, as well as some in the water.
It wasn’t until I processed the
pictures that I notice a solitary male King Eider among them. I wish I had
noticed it, I might have been able to get a better photo – although it was very
far away.
Back to Polar Bears
So, how about a little information about Polar Bears?

The Inuit call it Nanook (Nanuq in Inupiat); the Yupik call it Nanuuk in Siberian Yupik; the Chukchi use the name Umka; Russians call it Bélyj Medvédj (“White Bear”); and in Svalbard, the Polar Bear is Isbjørn ("Ice Bear").
The oldest
known Polar Bear fossil is a 130,000 to 110,000-year-old jaw bone, found in
2004 on Prince Charles Foreland, an island on Svalbard not far from where we
were floating in our Zodiacs. So, this truly is the Realm of the Polar Bear.
The Polar Bear
was previously considered its own genus, but it is now considered the same genus
as a Brown Bear. The Polar Bear has evolved to occupy a much narrower
ecological niche than its cousin, with its
body adapted for cold; for traveling across snow, ice and open water; and
for hunting seals. Although most Polar Bears are born on land, they are
considered marine mammals because they spend most of their time on sea ice.

Because neither species can survive long in the other's ecological niche, and because they have different morphology, metabolism and social and feeding behaviors, the two types of Bears are generally classified as separate species.
Because there are few humans in most Polar Bear habitat, they retain more of their original range than any other carnivore. Rare north of 88°, they can range all across the arctic as far as the boundary between the subarctic and humid continental climate zones.

They can drift widely with the sea ice, sometimes ending up much
farther south. And, even though they are marine mammals, the sometimes stray
inland.
In 2018, a sow showed up at a research station at 10,500 feet elevation in the middle of the Greenland Ice Sheet more than 200 miles from the nearest coast. I overheard one of the researchers talking about it in an airport in Fairbanks when I was on my way to Bettles last summer and later read news articles about it.

The five
nations with active Polar Bear populations – Denmark (Greenland), Russia, the United States (Alaska),
Canada and Norway (Svalbard) – are signatories of the International Agreement
on the Conservation of Polar Bears, which mandates cooperation on research and
conservation.
Biologists estimate
there are 20,000 to 31,000 Polar Bears worldwide. Because of expense, they have
been actively tracked only since the mid-1980s. The most accurate counts
require searching by helicopter (in a tricky climate) and then tranquilizing
and tagging the Bear.
On the moraine |
Polar Bears
prefer areas where sea ice meets water where seal density is high. As seals
migrate in response to changes in sea ice patterns, Polar Bears follow them.
When the ice melts, the Polar Bears go onto land wait until the next freeze-up.

Their 12-inch-wide feet distribute load on snow or thin ice and provide propulsion when the Bear swims. The pads of the paws are covered with small, soft bumps that provide traction on the ice. Their deeply scooped claws are short and stocky compared to those of the Brown Bear, to provide a tool for gripping the ice, digging in the snow and ice and for snagging slippery prey.
Polar Bears are
insulated with up to 4 inches of fat, thick hides and dense fur that consists
of underfur and an outer layer of 2-to-6-inch-long guard hairs, which appear
white to tan but are actually transparent.
Their skin is black to absorb and hold heat. Polar Bears overheat at temperatures above 50°F and, because they are so well-insulated, they are nearly invisible to infrared photography.
They molt from May to August, but, unlike other Arctic mammals, do not shed their coat for a darker shade to provide camouflage in summer conditions. After all, what do they have to fear (besides man)?

The Polar
Bear’s white coat usually yellows with age. Boars have significantly longer
hairs on their forelegs, which increase in length until the Bear reaches 14
years old. The ornamental foreleg hair is thought to attract sows, serving a
similar function as the Lion's mane.
The Polar Bear
has a well-developed sense of smell and can detect seals nearly a mile away and
buried under 3 feet of snow. Its hearing is about as acute as that of a human
and its vision is good at long distances.

The Polar Bear
is an excellent swimmer, often swimming for days. With its body fat providing
buoyancy, it swims in dog-paddle fashion at about 6 mph. When walking, the
Polar Bear has a rolling gait and maintains an average speed of around 3.5 mph.
When sprinting, it can reach up to 25 mph for short distances.

Unlike Brown Bears, Polar Bears are not territorial. Although stereotyped as being very aggressive, they are normally cautious and often choose to escape rather than fight. They lead very tough lives and don't need to make things harder for themselves. Polar Bears rarely attack humans unless severely provoked. However, due to their lack of human interaction, they don't really differentiate between humans and other potential prey. Hungry Polar Bears are unpredictable, fearless towards people and are known to kill and sometimes eat humans.
Polar Bears are stealth hunters, and the victim is often unaware of the bear's presence until attacked. Attacks are generally predatory and are almost always fatal.
Although
generally solitary, Polar Bears sometimes play together, especially cubs and young
males that play-fight to practice for serious competition during mating seasons
later in life.
Polar Bears eat
primarily Ringed and Bearded Seals, but only big males can kill an adult male
Bearded Seal. Mature Bears tend to eat only the calorie-rich skin and blubber
of the seal, which are highly digestible, whereas younger bears consume the
protein-rich red meat.

The Polar Bear stalks Seals resting on
the ice, slowly creeping to within 30 feet and suddenly pouncing.
Bears also
raid seal dens and scavenge carcasses from other bears' kills if they can.

Bears also eat plants, including berries, roots and kelp but, because they require large amounts of fat from marine mammals, they cannot derive sufficient calories from terrestrial food. In Svalbard, Polar Bears have been observed killing White-beaked Dolphins in the spring when the dolphins were trapped in the sea ice and then caching the carcasses to eat in the ice-free summer and autumn.
After feeding,
Polar Bears wash themselves with water or snow.
Unlike Brown and Black Bears, Polar Bears can fast for several months. This is important in late summer and early fall, when there is no sea ice and they cannot hunt seals.
With the
exception of pregnant females, Polar Bears are active year-round. Courtship and
mating take place on the sea ice in April and May, when Polar Bears congregate
in the best seal hunting areas. A boar may follow the tracks of a breeding sow
for 60 miles or more, and after finding her, engage in intense fighting with
other males over mating rights, fights that often result in scars and broken
teeth.

After mating,
the fertilized egg remains in a suspended state until August or September.
During these four months, the pregnant female eats prodigious amounts of food,
gaining at least 400 lbs.
When the ice
floes are at their minimum in the fall, ending the possibility of hunting, each
pregnant female digs a maternity den consisting of a narrow entrance tunnel
leading to one to three chambers. Most maternity dens are in snowdrifts, but
may also be made underground in permafrost or on sea ice. In the den, the sow
enters a dormant state similar to hibernation in which her heart rate slows
from 46 to 27 beats per minute but her body temperature does not decrease as it
would for a typical mammal in hibernation.
Between
November and February, cubs are born blind, covered with a light down fur and
weighing less than 2 lbs. Most litters comprise two cubs, although three are
possible. The family remains in the den until mid-February to mid-April, with
the mother maintaining her fast while nursing her cubs on a fat-rich milk. By
the time the mother breaks open the entrance to the den, her cubs weigh about
25 lbs. For about 12 to 15 days, the family spends time outside the den while
remaining in its vicinity, the mother grazing on vegetation while the cubs
become used to walking and playing. Then, they begin a long walk to the sea
ice, where the mother can once again catch seals. Depending on the timing of
ice-floe breakup in the fall, she may have fasted for up to eight months.

Polar Bears
rarely live beyond 25 years. The oldest wild bears on record died at 32,
whereas the oldest captive Polar Bear died at 43.
In the wild, old Polar Bears eventually become too weak to catch food and gradually starve to death. Bears injured in fights or accidents may either die from their injuries or become unable to hunt effectively, leading to starvation.

Brown Bears
tend to dominate Polar Bears in disputes over carcasses, and dead Polar Bear
cubs have been found in Brown Bear dens.

Only the liver was not used because its high concentration of vitamin A is poisonous. Hunters either throw the liver into the ocean or bury it to protect their dogs from being poisoned.
Traditional subsistence hunting by indigenous peoples was on a small enough scale to not significantly affect Polar Bear populations, mostly because of the sparseness of the human population in Polar Bear habitat.
However, as hunters took to the seas, that changed.
In Russia,
Polar Bear furs were already being commercially traded in the 14th century, although
it was of low value compared to Arctic Fox or Reindeer fur. The growth of the
human population in the Arctic in the 16th and 17th century, together with the
advent of firearms and increasing trade, dramatically increased the harvest of
Polar Bears. In the early 20th century, Norwegian hunters were harvesting 300
bears per year in Svalbard.
In the first
half of the 20th century, hunting changed: Bears were chased from snowmobiles,
icebreakers and airplanes; and guns and traps became more sophisticated. The
numbers taken grew rapidly in the 1960s, peaking in 1968 with a global total of
1,250 bears that year.
Concerns over species survival led to regulations on Polar Bear hunting beginning in the mid-1950s.
In 1973, the International Agreement on the Conservation of Polar Bears bound member countries to restrict recreational and commercial
hunting, including banning hunting from aircraft and icebreakers.
The treaty
allows hunting "by local people using traditional methods."
Norway is the only country of the five in which all harvest of Polar Bears is banned (I think they figured out that live Polar Bears are better for tourism, plus they don’t have any indigenous peoples). Now, Norway needs to get onboard with whaling!
Still, the
bears face challenges from climate change, primarily malnutrition or starvation.
Rising temperatures cause the sea ice to melt earlier, driving the bears to
shore before they have built sufficient fat reserves. Reduction in sea-ice
cover also forces bears to swim longer distances, further depleting their
energy stores and occasionally leading to drowning.
Problematic
interactions between Polar Bears and humans, such as foraging by bears in
garbage dumps, have historically been more prevalent in years when ice-floe
breakup occurred early and local Polar Bears were relatively thin. Increased
human-bear interactions, including fatal attacks on humans, are likely to
increase as the sea ice shrinks and hungry bears try to find food on land.
Polar bears are
the iconic symbol of Svalbard, and one of the main tourist attractions.
Svalbard and Franz Joseph Land share a common population of 3,000 Polar Bears.
The animals are protected and people moving outside towns are required to have
appropriate scare devices to ward off attacks and are advised to carry a
firearm for use as a last resort. Polar Bears are dangerous: There have been two Polar
Bear attacks in Svalbard in the past 10 years. In 2011, a British student was killed
and four others were injured; in 2018 a cruise ship bear guard was attacked.
