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 […]

Featured Videos of the Month: June, a Visual Essay

Mountain lion on the trail

June was a visually exciting month on the trail. A mountain lion visited a week ago—he stayed for a couple of days before moving on. There’s a new bobcat on the trail he sports a beautiful dark coat. And, our resident coyote, 09M, continues to make his mark. Mountain lion A male mountain lion visited […]

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 […]

Dusky-Footed Woodrats Help Save a Canyon

Woodrat homes are elaborate with multiple stories and an abundance of rooms that include resting chambers, nurseries and pantries.

I’ve never been particularly partial to rodents who resemble rats. In fact, I try to avoid them. That changed after one of my wildlife cameras filmed a number of surprisingly adorable, industrious little rodents gathering sticks and leaves late at night. This was my first introduction to the fascinating dusky-footed woodrat. (Neotoma fuscipes). These little […]

Our Wildlife Cameras Record Everything

Finally it’s the beginning of summer and the trails are alive with activity—human and animal. Our wildlife cameras are capturing it all, including those changes that are caused by natural seasonal cycles as well as adaptations in animal behavior that are likely influenced by people out on the trails day and night. Summer changes The […]

A Diversity of Animals Share a Popular Trail

Bobcats use the trail on a regular basis.

Camera #4 films the most activity of the 6 cameras I’m monitoring. It’s located in an ideal spot for sighting animals—on a trail that follows a creek at the bottom of a lush canyon. A wide diversity of wildlife and humans use this trail 24 hours a day. I understand—it meanders through a cool forest […]
