A Mouse of the North Woods

Southern Red-backed Vole (Myodes gapperi), Kiskatinaw Campground, British Columbia


There wasn't much time for camera trapping when we had only a month to drive 7000 miles and see the sights on the AlCan Highway.

There was no time to hump through the muskeg or climb through the slash.

I told myself to forget about lynx, wolves, and wolverines and set my sights on campground fauna.

And that's where I met the Southern Red-backed Vole (hereafter RBV).

They greedily scarfed sunflower seeds before my camera traps.

I expected deer mice, but the Southern RBV seemed to be the dirt-common mouse of the north woods.

I found them in conifer forests, aspen groves, and degraded woodland common around RV parks. 


I thought voles were herbivores, but red backed voles are more omnivorous than many voles of the genus Microtus, and they also eat underground fungi.

Some related voles are good climbers, but the Southern RBV's short legs, long chassis, and short tail is designed for running on the ground.

And unlike meadow voles, they don't engineer tunnels in low growing vegetation.

The Southern RBV is found across Canada, and ranges as far south as the Columbia River in the northwest US, but it apparently managed to reach New Mexico and Arizona via the Rocky Mountains.

It's well adapted to northern climes, starts breeding under thick snow, and lives a year on average, though a few survive to see a second winter.  

I appreciate this denizen of the north woods, and was pleased to add it to my list of camera-trapped  critters.

Happy Hour in Whitefish

Logger Bob Love, the real thing.


August, 6 -- Whitefish, Montana

It was our last day at Carl's cabin, because we were heading North to Alaska the next day.

We drove to Kalispell for supplies and to have a tire repaired,and then we pigged out on barbecue.

Food coma soon followed, and we headed home.

Carl had the foresight to save some of the meal for the ladies, who had been busy at the cabin, and this made our power-naps somehow excusable.

When we awoke the woods were rumbling. So we strolled over to watch Logger Bob sawing and munching piss firs with his machines.

Bob is the real thing. No lumbersexual wears pitch-stained pants, and smells like chain saw exhaust.

Carl hired Bob to thin the piss firs, "because they crowd out the larches and pines".

"They're as common as wood rats around here, and they stink like rats, too."

(Carl always abuses my favorite rodent in my presence.)

Yep, Piss firs. I hadn't heard of them either.

The colorful moniker comes from the subalpine fir's habit of releasing a stream of water when bored with a forester's auger. So says the Slang Dictionary. 

Break time in the pickup.
While we admired the machinery, Bob's dog Sparky hunted Montana's other native scoundrel, the bushy-tailed wood rat.  

Sparky knows where to find these handsome rodents, and how to flush them, and if he doesn't nail them on the run, he trees them and stands vigil till they come down and make a run for it. 

Our dogs Fred and Petey found Sparky to be a really neat guy, and joined him in the chase, but they just didn't get the waiting game under the tree.

Sparky stood vigil while
Petey and Fred wanted in.
Fred can't even catch a squirrel, and thinks the game ends when the squirrel goes up the tree.

So when Sparky treed a rat that afternoon our dogs drifted off and were soon looking wistfully into the cabin.

Before long it was happy hour, and a chance to chat with a real Montana logger.

We gathered on Carl's porch next to the beer cooler where Moose Drool and other brews greased the skids.

Soon we swapping stories about trees, timber, wood, land, and of course wildlife.

Old snags?  Bob knew of a big one used by bears as a hibernaculum.

I asked if he had ever seen a wolverine out here. 

I doubted he had, but I was wrong.

"I passed one on the shoulder of the road one morning.

"It had it's head up the butt-end of a road killed deer, and was within shooting range of any passing pickup. 

"So I walked it away from the road and called the game warden."

"The warden dragged the carcass up into the woods, and the wolverine survived a close call with civilization.

Salted into Bob's accounts was the name of Bud Moore.

Moore grew up in the Bitterroots, trapped and built cabins as a teenager, was a Marine during WW2, and worked for the Forest Service most of his life.

He was one of those rare individuals who "listened to the land and learned from it".

"Bud was like my brother, grandfather, father, mentor and best friend. It was like we'd known each other in previous lives, and reconnected.  We will again one day."
  
Moore was a toddler when writer Norman MacLean worked for the Forest Service, but their paths crossed decades later when MacLean needed a fact checker for his draft of A River Runs Through It.

In Bob's words . . .

"McLean didn't know Bud at the time, but since Bud knew the country and characters in the stories, he asked him to check the manuscript for facts.  In Bud's words, 'I took my red pencil to it and sent it back'.  The edits didn't go over well, but Maclean eventually agreed they were warranted."

"Bud was on the team that investigated the Mann Gulch fire, and was responsible for the Fire Fighter's standard safety rules, which are still in effect today."

"They are fashioned after the Marine Rules of Battle Conduct.  Bud had been in the Marines, and couldn't recall the rules to the letter, but he thought they'd be applicable to fire fighting."

"The team was meeting in DC, near some military facility.  Bud went out and found a Marine at a bus stop, and asked him to recite the rules.  He wrote them down, brought them back to the meeting, and they were adopted by the FS."

The Maclean-Moore relationship grew into one of mutual respect, and when Moore was writing The Lochsa Story he observed that "McLean took care of my inclination to put outdoor pursuits first, desk work last. Every time I dropped my pencil and looked at my fly rod, he would show up in some form or another."

I had one last question before Bob headed home.

"What's wrong with Sparky's paw?" (Sparky favored one paw. Was it a casualty of the chase?)

"Compound fracture", said Bob. "He broke his leg when he fell off a roof, trying to get deer fat I'd put up there for ravens.   

"Maybe I should have had it cut off. He wouldn't be in such pain, but he wouldn't be able to catch wood rats either." 

It was a happy hour I won't forget.
