Mountain Lion Latrines and a Scent Dog

The highly-tuned nose of a talented scent dog found mountain lion latrines at the rim of the canyon. Latrines are spots where pumas, often family groups, will repeatedly defecate; they are the mountain lion equivalent of toilets, except instead of flushing, pumas cover their excrement in these locations. But, lions don’t arbitrarily choose places for […]

Why steal a research trail camera in the canyon where we are recording wildlife? That stolen trail camera was an important conservation tool and the videos it recorded helped educate the public about the impact of urbanization on our local wildlife.

The 88-acre canyon is a wildlife oasis, regularly visited by puma, coyote, deer and other animals, located in the middle of a suburban landscape.

Puma scraping

It isn’t a coincidence that there are a number of small mounds of leaves, twigs and soil grouped in a clearing surrounded by tall redwood trees and oaks.  They’re not random; the piles, called community scrapes, were intentionally made by mountain lions.

Mountain lion #2 walking the trail

Today’s a sad day. Another mountain lion died, hit by a vehicle not too far from the canyon. I’m worried that the victim may be the big male we’ve been monitoring on the canyon trail since early this year. The one who died tried to cross the freeway at 10:00 Friday night. Perhaps the lion […]

Predators Scent Mark a Popular Spot on the Trail

Predators including bobcats, mountain lions and coyotes who don’t want to share resources as well as those who do, are adept at communicating their intentions through scent marking—to their own as well as other species. And often, they scent mark on top of each other’s mark. It’s not always in the best interests for predators […]
