[quote:Bluebird:MV85MzI5NDBfMTQ2MDM3MTVfREE3OTYwNTk=] [quote:PACNWguy] ALL male bears eat cubs. This is just the way it is. Next they will say global warming is responsible for fish to eat their babies too. What a bunch of morons. Call the zoo and ask them why they dont let the male bears play with their cubs. :lol: [/quote] Same with the pandas and the very young cubs. No daddy allowed. As long as the female is nursing, she is not likely to go into estrus and mate with him. Happens in a lot of species. And since polar bear numbers are on the increase, it's doubtful food is the issue. [/quote]
Original Message
Scientists say shrinking Arctic sea ice may be forcing some hungry polar bears to cannibalize bear cubs.
At least seven cases of mature male polar bears eating bear cubs have been spotted this year among the animals around Churchill, Man.
Ian Stirling, a retired Environment Canada biologist who specializes in the Churchill bears, calls it the highest incidence of cannibalization he has ever seen.
Stirling says evidence suggests the cubs are being killed for food, not just so the male can mate with the sow.
He says the Hudson Bay sea ice, which the bears use to get at the seals they need to fatten up for winter, isn't appearing until weeks later than it used to.
