Polar Bears eating polar bears:
============
ANCHORAGE, Alaska (AP)?Polar bears in the southern Beaufort Sea may be turning
to cannibalism because longer seasons without ice keep them from getting to
their natural food, a new study by American and Canadian scientists has found.

The study reviewed three examples of polar bears preying on each other from
January to April 2004 north of Alaska and western Canada, including the
first-ever reported killing of a female in a den shortly after it gave birth.

No, this is believed to be related to lack of food sources.

Rather than force you to use the brain god gave you, I'll give you some other

Polar Bears May Be Turning to Cannibalism Longer seasons without ice may force
polar bears to turn to cannibalism, scientists say

ANCHORAGE, Alaska, Jun. 13, 2006

Are Polar Bears Victims of the New Cold War?

Climate change may be affecting the bears? habitat. By Emily V. Driscoll,
posted February 5th, 2007.

A male polar bear is stalking his prey. Suddenly, he makes a beeline for his
target. Punching a massive paw through the victims? snowy den, he gives his
prey, a mother and two offspring, little chance. The bear bites down on her
neck. The ensuing struggle collapses the den, suffocating the cubs.

But the victims are not ringed or bearded seals, typical polar bear food. They
are also polar bears, victims of a perplexing act of cannibalism that
researchers fear may become increasingly common as global warming puts more
pressure on the Arctic?s largest predator.

Oh bother, said Pooh.

Take care,
Janis
