The highly-tuned nose of a talented scent dog found mountain lion latrines at the rim of the canyon.

A Wildlife Oasis in Suburbia
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. It is shoehorned between homes and businesses, perched on the rim of the canyon, bordered by busy roads and separated from other similar, small wild spaces. Fragments of the Wild Although […]
Summertime Brings Changes to the Canyon Wildlife

A wide diversity of wildlife and humans use this trail 24 hours a day. I understand—it meanders through a cool forest […]
Long Distance Relationships with the Local Wildlife
Our trail cameras have spied on a rich array of wildlife, including bobcats, foxes, mountain lions, coyotes and deer. Many of them are regulars—repeatedly visiting the cameras for the last 6 months. I’ve gradually learned to recognize individuals. Through recognition comes attachment—I confess that I’ve named some of them. These 4-legged visitors have great reasons […]
