Wildlife Highlights from the Canyon

Vulture

Life and Death in the Canyon Despite the canyon being only 93 acres, hemmed in by homes and roads, it’s a complete eco-system where plants and animals are interdependent. The death of one organism means many others will live. The lesson hit home a couple of weeks ago when a small deer was killed by […]

September Videos and Pictures

Mountain lion

There seems to be less wildlife in the canyon this month. It could be a natural cycle or it might be caused by destruction that is occurring in part of the habitat. Mountain lion This large male puma is a regular visitor to the canyon–he shows up about every two to three months. This time […]

Life Stories of Two Canyon 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 […]

The Bobcat Kittens Grow Up

It’s hard to describe the anticipation I felt last summer as we waited for the wildlife cameras to finally catch glimpses of adorable bobcat kittens trailing closely behind their mum. We knew that we would soon see them because a couple of months before the cameras had recorded a resident bobcat going through stages of […]

City Coyote Moves to the Suburbs

Coyotes 09M and mate

I used to have mixed feelings about coyotes. When I was a child late at night, I loved drifting off to the howls, barks and yips from coyotes—their vocalizations added depth to my sleep. While I felt in awe of coyotes, at the same time I was afraid of them. I grew up hearing stories […]

Rat Poisons Aren’t Selective

San Mateo, California is an affluent, suburban community where residents enjoy mild weather and amenities such as up-scale restaurants and specialty shops. In addition to people, common rats also enjoy living the good life here. They’ve adapted well to the near-perfect climate all year round and the gourmet food that is just a short scurry […]

Bobcats and Feral Cats on Patrol

“Cats are cats” was the response from my zoologist friend as we compared how bobcats and feral cats select, patrol and live in their ranges. Thanks to our trail cameras we have hundreds of 20 second videos to watch—superb vignettes of the resident bobcats on patrol in the canyon. Like all felids, bobcats and feral […]

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 […]
