Neighbor calls a biologist: ‘There’s a cougar in my backyard.’ And he says...
Trevor and Audrey Diddel live in Snoqualmie, Washington, a town 25 miles east of Seattle that has absorbed the big city’s growth and become a suburb at the foot of the Cascade Mountains.
Interstate 90 is close to their home, there’s a Subway around the corner — and a cougar in their backyard.

Interactions with the reclusive feline are increasing in this area.
Rocky Spencer, a cougar biologist with Washington state, said he got a complaint from a woman one morning saying, “There’s a cougar in my backyard!” Spencer replied, “Well, that’s funny, because I got a call this morning from a cougar. He told me there’s an woman in his front yard!”
Our backyards are getting bigger, and the cougar’s front yard is getting smaller. Since 1980 the population of Washington state has gone from 4 million to almost 7.5 million. Development has been spilling out from urban centers into cougar habitat.
To understand the impact cougars and humans have on each other we turn to Brian Kertson, a research scientist with the Washington state Department of Fish and Wildlife. He’s been studying cougars in this area for nearly 20 years, trying to learn how cougars are responding and adapting to human development.
On this episode of The Wild, we follow host Chris Morgan and Kertson on an adventure to track down a cougar den and work out how we continue to coexist with cougars.
Kertson explained a bit of the process:
Capturing the kittens at the den is critical for accurately quantifying reproduction for use in population models. It is the most reliable way to get a measure of the number of kittens born to adult females in a given year (i.e., maternity) and ultimately, fecundity (a combination of adult female survival and reproduction).
Marking the kittens also allows us to identify them after they become independent.
We do our best to make the process as stress-free as possible, for both the adult female and the kittens.
He updated us later to say that after this trip to the den, the adult female only moved it about 70 meters from the location we found it. And at least two of those kittens were still alive this winter.
Note: We of course have to warn you against handling cougar kittens. These kittens were being held to assist Kertson with his work of tagging and researching the animals.
