Winter
Polar Bears migrate with their young every year. When temperatures warm up Polar Bears migrate to land to find food.
* 17 polar bears die every year acording to average
Polar bears are mammals, so they bear live young. What is different about polar bears is that the implantation of the fertilized egg is delayed until the time of year is right for cubs to be born. It takes 65 days from that time and cubs are usually born between November and January in the den.
The struggle that polar bears face is starvation due to global warming. They can only hunt when there is sea ice covering the Arctic Ocean during the winter. As the warm part of the year gets longer and the cold part gets shorter, polar bears have less time to hunt for food and more time to wait without it. Therefor, as the climate gets warmer, the more polar bears starve.
Not really. They don't travel far distances like whales and most birds do, they stay in the same area year after year. Sows "migrate" inland during the winter to hibernate and give birth to her cubs, but then travel out to the sea to begin hunting. During the short summer months polar bears are found on the mainland close to the ocean living off of lichens and lemmings and probably some berries, not venturing out to the ocean.Polar bears will move inland during the winter to build their dens, which could be considered migrating. However, they don't do it cross-country like birds do, and don't move too far.
Polar bears do not have a routine like humans do. What a polar bear does in a day is never the same. There are numerous days where a polar bear is just travelling, not eating, or waiting out a snow storm. It all depends on the bear and the time of year, among many other things.
because sun bears are so use to being warm all year and polar bears can adapt better ( i reALLY DONT NO ?)
zero, penguins and polar bears live at opposite end of the earth.
For black bears and grizzly bears, from spring to fall, with heightened periods when bears come out of hibernation and when they're fattening up for hibernation. For polar bears, it can be any time of the year.

Polar bears predominantly eat seals and rarely prey on penguins. Penguins are not found in the same regions as polar bears, so it is unlikely that polar bears eat any penguins per year.
Yes, they are very dangerous. In fact, polar bears kill on average 263 people each year in Canada alone.
