How long does it take for a female bear to get pregnant?

Bears are induced ovulators, meaning that ovulation (the release of an egg from the ovary) only happens if a female mates. The female gestation period varies by species, but it is typically around six to eight weeks.

Here are the gestation periods for different bear species:

* American black bear (Ursus americanus): 63 to 70 days

* Brown bear (Ursus arctos): 180 to 250 days (varies with subspecies)

* Polar bear (Ursus maritimus): 150 to 250 days

* Asian black bear (Ursus thibetanus): 180 to 210 days

* Sun bear (Helarctos malayanus): 95 to 120 days

* Giant panda (Ailuropoda melanoleuca): 95 to 160 days

* Spectacled bear (Tremarctos ornatus): 210 to 240 days
