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!!!
• Theyre 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, theyre on their own in the wild. ?
• They mostly eat seals, although they can also eat
  fish, seabirds, even reindeer!
• If theyre desperate in the summer for food, they
  may eat berries and plants!
• After that, they mate, reproduce, and the cycle
  starts all over again!
