Do all bears hibernate?

As we have done in the EGB when we ask about bears right away we would have said that some bears are omnivores ... ie eat everything , salmon, fruits ... and hibernate during the cold winter months in sleep-like state , lowering your metabolism can all spend the winter months without feeding or move.

But if we speak properly and we could not assert such a lie , because now depends on other factors ...

If the winter is mild , some females do not hibernate , but spend the winter feeding on their young and also known by recent studies that some species of Ursus some specific areas have not made that hibernate during the winter.

Similarly, in 2011 , it was noted that some regions had different bears come out of their slumber several months before her due date because of high temperatures.
