Winter wildlife wonderland

Happy Winter, Happy Holidays, and Happy (almost) New Year!! 

Since our last post, we have transitioned from Fall to Winter, and we have been busy!
Earlier this month, we held our first ever fundraiser, Mystery Tracks, and it was a great success in many ways. Not only did we surpass our fundraising goal, but we had so much fun doing so! We also learned that, regardless of current skillset, there is a tracker in every one of us. Excellent work to all who came out to sleuth some tracks and make this a night for the books! And thank you to Jean’s Farm for hosting, Ecliptic Brewing for the keg, and Steve Engel for the masterful plaster track casts. 

We would also like to thank everyone who has donated or become a member this month!
If you're considering making a tax-deductible donation on behalf of yourself or a loved one,
there's still time to donate and help us start off strong in 2020.

Membership and Support

As a community-based, volunteer-run organization, each dollar makes a difference, and we could not do this work without you!
​We are Cascadia Wild!

Now that we are officially in Winter, the Wolverine Tracking Project winter surveys are in full swing! We are getting a lot of footage back from our camera surveys, and a handful of tracking surveys have also been completed. There’s a lot more ground and many months still to cover, but we are off to a great start and have a great group of volunteers helping out this season.  Thank you to everyone who is lending their hands, eyes, and time to help document the wildlife of our national forest. 

Camera surveys

In case you missed it, we have some big news...

WOLVES IN MT HOOD NATIONAL FOREST!

Gray wolves detected by Wolverine Tracking Project Camera Survey, 2019

Sources at ODFW indicate that these individuals, detected on separate occasions at different sites, could be the breeding pair of the White River wolf pack, who have taken up residency on the Warm Springs Reservation and the eastern edge of Mt Hood National Forest. A target species of the Wolverine Tracking Project, we are interested in how the presence of gray wolves will shape the ecosystem of the lands they chose to call home. In hopes of also helping to define their range, we will continue to keep a lookout for these newcomers with several cameras positioned along the forest boundary. As the pack grows and disperses, or as other wolves move in, we expect to see more of them. 

​Since the wolf detections above, snows have arrived on our mountain, just in time to greet the season. This means we are seeing a lot more of other kinds of animals at our camera sites, including another of our target species: the Sierra Nevada red fox.

This winter, we have 9 cameras located in the immediate Timberline/Government Camp area and an additional two in the outlying area, all specifically focused on targeting this subspecies, one of the most rare mammals in North America and endemic only to the montane slopes of the Sierras and Cascades south of the Columbia River. As winter sets in, they seem more drawn to our sites than in summer, and frequency of detection increases. This is perhaps due to higher concentrations of red fox at the “lower” elevations of our typical sites (their summer range may include the talus slopes where installing camera traps is more difficult). Or, perhaps they are more drawn to the meat bait in these leaner months. Here we can see video compilation of what looks like two different foxes timidly checking some sites: 

​In both of these videos, the foxes seem drawn to the meat and fox urine we have baited the tree with, yet they are exercising caution. In the second video, what appears to be the same fox came back at least three times over a course of 9 days. Compared to bears or wolverine, who are both notorious when it comes to getting their paws on food, canids tend to be more hesitant, and our Vulpes vulpes necator here is no exception. 

Read more about the Sierra Nevada red fox. 

Coyotes inspecting bait sites

Coyotes, almost a guaranteed visitor at many of our locations, can also be cautious when it comes to inspecting bait.

However, coyotes tend to quickly overcome their hesitation and are just as likely to go for a good roll in, or near, the bait (see above)! Whether marking their territory or perfuming their coats, this is one behavior we can almost always count on from these canids.

Family Felidae are also curious about the smells at a site. 

Bobcats inspecting the smells at a site

These bobcats are much less hesitant than their canid counterparts, however, and if they show an interest in the bait will generally directly approach it, sometimes even marking it with their scent before leaving (rubbing, urinating, or even rolling in it in less common instances).

Even deer will check out a bait site:

Two does inspect bait on a tree

Though, as herbivores, deer are not interested in bait as a food source, it is in their interest to know who else may be in an area, and so the site behooves inspection.

​Other times, they are just passing through...  

Clockwise from top left: a doe casually browses her way through the field of view; two does meander through the snow; a young buck contemplates some snowberries; and a yearling seemingly poses for his portrait.

We've been seeing a lot of family Cervidae this month, which includes both deer and elk. Elk seem to have very little interest in bait, though they do sometimes like to inspect cameras. Elk are seemingly always on the move, seeking out the best sites for grazing and shelter every couple of days. 

Female elk (cows) on the move

Like deer, elk are crepuscular. Generally, though not always, elk are found grazing at night in large herds (or harems). A ruminant, elk can graze about 20 pounds of vegetation a day! At daybreak or soon after, elk disperse into smaller groups and bed down in shelter (typically forested areas). 

Male elk (bulls) on the move

Male elk, or bulls, will often travel solo this time of year. Late summer to early winter is elk breeding season, or rut, and the mature individuals pictured here are likely in pursuit of a harem. 

Other animals who display little caution at sites? 

A black bear (left) inspects a snag belt (which collects hair for genetic analysis), and a female bear (sow, right) thoroughly inspects a site with her two cubs of the year (coy).

As mentioned above, bears are well-known for being brazen when it comes to food. More so, they tend to be thoroughly curious. As an apex predator, extreme caution is not a characteristic necessary to their survival, though they seem to take great interest in their surroundings. 

Some smaller animals are just as brazen as a bear...

Left to right: mice, Clark's nutcracker, and Canada jays are opportunistic at baited sites. 

...while other animals can be troublemakers. In the photos above, a striped skunk of family Mephitidae inspects and disassembles a hair snag belt. 

Weasels are often seen at our sites in winter, and they will approach bait fearlessly.

Long tailed weasels passing through our sites

The long-tailed weasels above, however, are not displaying interest in the bait. This could be because there is plentiful food for them, like mice, voles, and even larger animals like rabbits and chipmunks. Closely related to skunks and in the same family as wolverine (Mustelidae), it is not surprising that these animals have a diverse carnivore diet and display little caution. 

Some other animals tend to always be oblivious to the bait, like these snowshoe hares, though they often tend to perk up a little for the camera: ​

Two snowshoe hares seem to pause for a photo mid-bound. One hare is in its winter coat (left) and the other, detected before snowfalls, is still in its summer coat (right).

These members of family Leporidae sport large, snow-defying hind legs and have another helpful adaptation: camouflage. The hare on the right appears to still be wearing its darker summer coat, while the hare on the left has changed its seasonal coloration to match the freshly falling snows. Perfectly timed for the season!

Another fearless, though somewhat rare animal detected by our cameras? A herd of camera crew volunteers!

Camera crew are often seen during site maintenance checks in groups of two to four. The above photo shows a particularly large group at a field training earlier this season. Keep an eye out if you are in the woods this time of year: they are a joyful bunch and we hear it can be contagious.

tracking surveys

​Whereas cameras can offer rich detail of the wildlife they detect, they can only tell the story of what is directly in front of the lens and can miss the peripheral story of all that goes on around them. Tracking surveys step in to compliment the wildlife camera data, telling us a story of the life upon a landscape. Surveys are conducted by snowshoe on Mt Hood almost every winter weekend with groups of up to 12, which include two Cascadia Wild endorsed and trained Tracking Trip Leaders. The surveys follow 1.5 mile transects (and more if time allows) and document the tracks found along the way, including: track size, gait, track quality, and species identification. A lot can be learned about the land and wildlife by reading these signs. Read more.

One of the most easily distinguishable animal tracks in our forest is the snowshoe hare:

A helpful hint in identifying this species is to look at the trail pattern: there are four footsteps all together in one area, and another four together following it, indicating hopping. For these hares, the prints in the front of the clusters are actually the back feet, and the prints in the back of the clusters are the front feet. Hares will land with their front feet, followed by their back feet, and they will swing their large back feet forward further than their front, ready to spring into the next bound.

We've also been seeing quite a few squirrels: 

Squirrel (likely Douglas squirrel) tracks in snow displaying their characteristic double-register

​Here, each print is actually two prints - both the front and back foot stepping in the same spot. This is called a double register.

And we've even found some mice!

Mouse tracks in snow, also displaying the characteristic clusters that indicates hopping

The mouse has the same trail pattern as the hare: hopping, with all four feet coming down in the same area.

One of the more exciting tracking finds so far has been Pacific marten. The Pacific marten is also one of our target species: their presence is an indicator of healthy upper-elevation forest.

The trail of the marten can be seen above. Several times it appeared to slow to a walk, pause - perhaps looking around - and often kept to the cover of the small saplings. Marten, another mustelid, are also voracious carnivores and it's possible to imagine it skirting the trees on its meandering path, in search of a vole, deer mouse, or other small animal.

A Canada jay perches on a snowy bough

Occasionally, we even get to see wildlife! A common sight are Canada jays. While we do not keep data on these birds, we do like seeing their familiar faces. Like their Corvid cousins - scrub and Stellar jays, Clark's nutcrackers, crows, ravens, and so on - Canada jays are adaptable, have diverse diets, and are generally regarded as highly intelligent, personable, and sneaky. These characteristics lend them and others in family Corvidae the nickname "Camp Robber."

There are few better ways to spend a winter day than strapped into snowshoes documenting the wildlife in our backyard...

...and enjoying the scenery...

...with a great group of trackers:

Thank you all for being a part of Cascadia Wild, this year, in previous years, and in the years to come!

Until next time... 
Happy Solstice! Happy Winter!
Our best wishes to you in the New Year!
