Polar Bears and where to find them
Polar bears grow bigger than any other bear in the world.
The small head and shape of the polar bear are quite different from the other bears in North America. And, what’s also different, polar bears are truly predatory, unlike black bears and grizzlies.
Churchill Manitoba, on the western shore of Hudson Bay in Canada, is known as the Polar Bear Capital of the World. Of course, this also makes Churchill the Polar Bear Tourism Capital of the world. This is no surprise; who doesn’t want to see a real Polar Bears at least once in a lifetime. There are not many places where you can do that, apart from the Zoo, and that’s not the place where I feel comfortable seeing the wild animals locked up.
Baffin Bay, Nunavut, and Tuktoyaktuk, Northwest Territories are other places in Canada to spot Polar bears. These places are extremely remote and difficult to get to. The polar bears are found in the Arctic. They are most abundant in areas with annual sea ice and productive ringed seal populations.
Polar bears can weigh more than 500 kilograms and they are strong and dangerous. They can drag seals out of the ocean with their claws, and on occasion, they will attack humans. The polar bears are top of the food chain in the Arctic, where they feed primarily on seals. The bears get these seals from a platform of sea ice. Unlike their brown bear cousins, which live on land, polar bears are well adapted for survival on the frozen seas of the Arctic.
The primary conservation concern for polar bears is habitat loss and reduced access to their prey due to climate change.
What is their food supply
Polar bears feed on ice seals, specifically seal fat. This is the highest calorie food source possible, but they will take other prey when available. They hunt on the packed ice all through the arctic winter and head inland to the Arctic coast as summer approaches.
Polar bears are right at the top of the Arctic food chain and help to balance nature by preventing an overpopulation of seals.
A polar bear first breeds at four to seven years old and has one to three cubs every three or more years. As with other bears species, male polar bears kill bear cubs and smaller bears. According to Biologists, this might be the reason for pregnant females to migrate sometimes up to forty kilometres inland from the coast. This way they keep away from the big males. The lifespan of a polar bear is between 25 and 30 years.
