| Authors: | John M. Goodrich San J. Stiver |
| Abstract: | An adult male and an adult female black bear ( Ursus americanus ) were found in the same den in the Carson Range of the Sierra Nevada in Nevada. Co-occupancy of dens is very rare, and such behavior has never been previously reported for adult bears of opposite sex. |
