Mating and cubs : • • • • • Mating depends on the bears health and weight Males are quite rough, they can kill the female for food Bears mate in spring but it take a while for the male to seduce the female Once they’ve mated, male will leave and never see the cubs Bears in warm climate don’t hibernate and can mate at any time • It takes 3 to 9 months depending, on the species, to give birth • Some species have a delayed implantation so they can hold off fertilization until hibernation so cubs will be born in a warm and safe place • Bear cubs are born helpless, neither can’t they see nor hear or have teeth • Cubs weight around 1 pound when born (450g)
  4. 4. Hibernation : • Bears hibernate 4 to 7 months since food is scarse in winter • While hibernating a bear’s heartbeat goes from 40 to 8 beats/minute • Bears can give birth and and go back to sleep immediatly after during hibernation • Cub nurse themselves while their mother is sleeping • Bears can go for more than 100 days without eating or drinking • Bears don’t poop while hibernating • This time of lethargy is a great opportunity for scientist (gathering data, replace batteries in collar, studying…)
