Kevin Brennan, California Department of Fish and Game wildlife biologist, knows this mountain and its wildlife. Black bears are relatively rare in the San Jacinto range after the construction of Interstate 10.

But now there is not just one, but two — the Rite Aid male bear who migrated to Idyllwild from Banning and the Indio female who was relocated to the Santa Rosa Mountains.

Some residents, perhaps also recently relocated here, are concerned there is a bear about. What is the proper bear etiquette — what should one do and not do? And more importantly, is the bear dangerous and should we be afraid?

Brennan will talk about the black-bear history in these mountains, where they ranged for many years, their socialization, their habits and proper bear etiquette should you encounter one in your vicinity.

Since adopting Idyllwild as his home, the Rite Aid bear has recently favored Fern Valley, Cedar Glen, the Nature Center area and as far as the James Reserve, where he searched for and secured some sugar supplies. He has been photographed and videoed in his local travels.

Brennan will speak at the Idyllwild Library from 4 to 6 p.m. Thursday, July 27. His talk, “Living with Bears,” previews his position as a wildlife biologist. They and we — the bears, the mountain lions, the bobcats, the foxes, the deer and the coyotes — are here together and need to find ways to comfortably, respectfully and safely live together.

There is no charge to attend Brennan’s talk and Q&A at the Idyllwild Library Community Room, and gives residents, especially new residents, information that may be helpful.
