Can a Hybernated bear give birth ?

Question

Friend of mine is asking if a bear hybernate during the winter, would it be possible for them to give birth ?

Answer 1

That's precisely when the cubs are born. While the mother is in the winter den to hibernate, the cubs are born. They spend their first few months of life tucked in there with her. She snoozes, they nurse, and everybody comes out in the spring.

Answer 2

I just found the following in a website devoted to bears. This is specifically about black bears. Fascinating!!

Breeding season is in late June to early July. The fertilized egg matures to the blastocyst stage and goes dormant. Blastocyst will not implant in the uterus until late November. In early December, embryo development proceeds normally (delayed implantation: a process shared with badgers, mink, weasels, otters, and wolverines). Birth occurs in late January. Gestation is approximately 7 months. The delay in gestation is approximately 5 months and true gestation is approximately 8 weeks. A black bear usually has between 1 to 5 cubs.

Answer 3

As other answers have pointed out, bears normally
give birth in their winter dens. As I recall, however,
(I don't have references at hand at the moment to
check) the winter sleep of bears is not a true
hibernation. They are more active, and not as
deeply torpid as a genuine hibernator.

Answer 4

actually, the only time i saw a polar bear giving birth (on animal channel) was in the same place where it hibernates.
