The Polar Bear Life Cycle By: SanjanaRamchandran
Birth • Cubs are born from Nov.–Jan. in a den. They stay there with their mother until spring. • Weight: About 1 lb. • Polar bear cubs are so tiny at birth that they can fit in the palm of your hand!!! • They’re very helpless and are born with their eyes closed.
Polar Bear Cubs: • There are usually 2 cubs per litter • Mother polar bears are VERY protective of their young • Open their eyes within a month • Start walking at two mos. • Start eating solid food at 3-4 mos. • Learn to hunt from watching their mom • I was very sad to find out that: when cubs are about 30 mos. old, an adult male may start following the mom. At this time, the mom or the male will chase away the cubs.
Adult Polar Bears: • Polar bears start mating every other year in mid-summer. • After that, they’re on their own in the wild. • They mostly eat seals, although they can also eat fish, seabirds, even reindeer! • If they’re desperate in the summer for food, they may eat berries and plants! • After that, they mate, reproduce, and the cycle starts all over again!
