The days are getting warmer and longer, the birds are returning from winter migration, and animals everywhere are bringing a new generation of wildlife into our forests...needless to say, winter has ceased and made way for spring, marking the end of our winter survey season. While this season may have been unexpectedly cut short, the Cascadia Wild team of volunteers and members still managed to bring in countless wonderful photos and record many wildlife tracks while it lasted.

Please enjoy this season recap of the Wolverine Tracking Project's Camera and Tracking Survey highlights!

This winter season, a total of 1,447 volunteer hours went into camera survey trips!​

Together, we maintained a total of 21 cameras at 25 camera sites over the winter season.

Over the survey year (which ran from Summer 2019 through Winter 2019-20), our camera sites were divided into two general areas: those near Mt. Hood, and those near the eastern edge of the National Forest boundary, with the intention of targeting different kinds of animals. 

The tables below show the animals detected at each site over the winter season:

A total of 18 different animal species were detected by our cameras, along with a few mystery species pictured below...

Our cameras even captured 3 different target species!

The beautiful Sierra Nevada red fox was pictured at 4 separate camera sites this winter!

Another target species, the gray wolf, was seen at 2 camera sites...

And our final target species was pictured at one camera site: the Pacific marten!

While these target species are incredibly exciting to capture on camera, so are the many other animals that passed through our camera sites!
​
Our most frequent visitor was present at over 64% of all camera sites this winter... You guessed it: the coyote!

Another frequent visitor was the black-tailed deer, present at 52% of our overall camera sites, and over 92% of the eastern forest boundary sites!

Deer weren't the only ungulates spotted in our forests this winter. Elk were present at 5 different camera sites, all in the eastern forest boundary:

Appearing at 10 camera sites, the bobcat was another regular:

The largest felid in our forests, the mountain lion, was present at only 1 camera site this winter:

The black bear was seen at 2 camera sites this winter, including once with some cubs!

Many forest rodent inhabitants made their way into our camera sites, such as squirrels and mice.
Can you spot tell which is a Douglas squirrel and which is our native, nocturnal Northern flying squirrel below?

Snowshoe hares were present at 8 camera sites...

And luckily, we only faced minor sabotage by the striped skunks, who made their way into 5 different camera sites...

A huge THANK YOU to all of the volunteers that made this winter season so great - we look forward to another great summer survey season!

This winter season, a total of 1,213.5 volunteer hours were put into tracking surveys! ​

In total, 47.5 miles were surveyed for tracks at 11 different transect locations! 
The map below shows the locations of our tracking trips this season.

Thanks to all your hard work and attentive tracking, 279 total tracks were recorded, consisting of 8 different species and some mystery tracks!

This table shows our tracking totals for the winter season:

By and large, our winter tracks were dominated by snowshoe hare and squirrel prints.
Pictured below are squirrel tracks (left) alongside snowshoe hare tracks (right).

This season, a total of 117 squirrel tracks were recorded, the most of any species this season!

Second in frequency to squirrel were snowshoe hare, with a total of 113 tracks!

Another frequent sight on these tracking surveys was the deer mouse, with a total of 21 tracks recorded.

Weasel tracks were recorded a total of 13 times​:

Our tracking teams even picked up a target species: the Pacific marten!

A total of 6 coyote tracks were seen...

...and a total of 9 bobcat tracks

Our volunteers also found some beautiful raven tracks in the snow!

​Some mystery tracks were not clear enough to properly identify...

Along with animal tracks, our wildlife tracking teams also found other signs of wildlife in our forests, including these small sticks that indicate a small animal chewing the cambium for food...

...and a tree with signs of bark removal at the base (perhaps from a bear eating the cambium), consumption of the exposed inner tree by insects, and finally, marks left by a woodpecker eating the insects inside the tree.
​So much history visible in one tree!

Near the base of this sign post are marks left by a bear:

Our tracking teams also found a small mystery den:

With so many animal signs recorded - both tracks and otherwise - it has undoubtedly been a very successful winter tracking season!

All in-person classes and events have been cancelled for the time being (read our COVID-19 Statement). However, we are hopeful, planning on, and looking forward to our summer survey wildlife survey season. 

Late winter/early spring is the perfect time to get to know our local songbirds, and our Bird Language Series is a great opportunity to do so! Beyond bird identification, this 8-class series in field and classroom explores what the postures, song, chatter, and even silence of birds can tell us about what's happening on the landscape  - the location of predators, presence of other humans, and even our own awareness and mindset. Starting March 22. Read more.

There has been an ​abundance of wildlife sightings on Mt. Hood this past month, including our beautiful and elusive target species: the Sierra Nevada red fox!

The Sierra Nevada red fox was first confirmed on Mt. Hood in 2012 by Cascadia Wild's trail cameras under the Wolverine Tracking Project. Despite their small numbers, attempts to list these animals as threatened or endangered have failed in recent years due to the lack of information on their populations and whether or not they are interbreeding with other red fox subspecies.
​
Cascadia Wild uses data collected on this subspecies to aid researchers and conservationists in their attempt to protect the Sierra Nevada red fox. Due to their elusive nature, there are many questions left to be answered, such as their population sizes, distribution, genetics, and ecology. Data is gathered by Cascadia Wild through our camera surveys, winter tracking surveys, and summer scat surveys.

These foxes are always an exciting find, and they have graced our higher-elevation cameras a handful of times this season. Their curiosity of the bait trees are hard to misinterpret, and the body language they exhibit is not unlike that of our canine companions.

Some fun facts...

• The Sierra Nevada red fox is considered to be one of the rarest mammals in North America.
• These foxes are generally solitary animals and tend to be nocturnal, doing a majority of their hunting at dusk or in the night.
• Their habitat tends to vary in elevation from 4,000 ft - 12,000 ft. They are thought to be seasonal elevational migrants, moving to higher elevations in the summer months.

Coyotes are generally monogamous and tend to maintain pair bonds for life. Their litters are raised by both parents and parenting duties are also frequently taken on by older siblings in the family group. They travel both alone and in packs usually consisting of an alpha male and female, their relatives, and some members of other families. 
​​
Coyote packs tend to live in territories that they will defend against neighboring packs. They mark these these territories with scent markings such as urine, feces, and rubbing against objects like trees.

Some fun facts...

• Coyotes can run up to 40 mph.
• Coyotes are very strong swimmers.
• On occasion, coyotes will interbreed with wolves, creating a hybrid species referred to as a "coywolf".
  
• These canids make their homes in forests and mountains, wetlands, meadows, and even urban cities.

Other carnivorous mammals caught on our cameras this past month include the stealthy bobcat​.

Bobcats have a wide range of diet, including small mammals such as hares, squirrels, birds, and even the occasional larger game like deer. Bobcats use their stealth to hunt, remaining hidden to their prey until they attack with a leaping pounce of up to 10 feet. ​

These felines are the most common wildcat in the United States, yet they seldom cross paths with humans due to their solitary, nocturnal, and elusive nature.

A common meal of the above carnivores are the snowshoe hares.

Snowshoe hares have evolved to molt to a white coat for the winter to match the snowy backdrop, and molt back to brown once the snow melts away; this way, they do not stand out like little lightbulbs in the dark forest, and they are able to camouflage with their environment year-round. However, as demonstrated above, sometimes these color changes do not happen as they should. As the global climate changes, the presence or absence of snow at different times of the year becomes less predictable, and hares are sometimes unable to quickly change their coat to match - a phenomenon biologists call "camouflage mismatch".
​
Abundant in our forests, the snowshoe hares are nimble and fast; a necessary advantage as a favorite snack of bobcats, coyotes, foxes, and even some birds of prey. These hares have large, fuzzy feet that help them to  effectively navigate their snowy habitats, similar to the snowshoes of our volunteers.

Other herbivorous inhabitants of our forests include the black-tailed deer​.

Black-tailed deer inhabit the forested mountains and foothills near the Pacific coast. They are resident animals, meaning they do not migrate south, but do tend to move to lower elevations during the winter months. Their home-range consists of about 3 square miles of land, yet they tend to travel in solitude - aside from the small family groups of mothers and their young, or the bachelor groups of bucks formed during the summer months.
​
You can find more information about deer in our last blog.

A flehmen response is a reaction to intriguing smells - commonly urine - where the upper lip of the animal is curled back to expose the vomeronasal organ to the scent in order to get a good whif. In fact, the word "flehmen" comes from the German verb for "to curl". However, this response is not just "sniffing" - it may be compared to sniffing in high resolution.

This black-tailed deer doe is seen exhibiting a flehmen response, likely in response to the urine of another deer. You may have observed a cat or another ungulate like a horse displaying this same behavior before. While not uncommon, a flehmen response is more frequent in black-tailed deer males than females. In fact, there seems to be an annual cycle for flehmen responses in black-tailed deer; observations are much more frequent in the winter during breeding season as deer are on the lookout for a mate.

​Also seen is a less common winter visitor: a striped skunk.

Striped skunks tend to hole up for the winter; however, similar to bears, they do not undergo true hibernation. Instead, both skunks and bears exhibit something called torpor: a state of decreased metabolic and physiological activity, allowing an animal to survive through periods of food shortages. ​More information on torpor can be found in our last blog.

Though skunks tend to be known for their foul smelling spray, they are actually docile animals that will happily leave humans alone and go on with their day. Their spray defense is typically only used as a last resort; if they feel threatened, they will first try to run away from the threat. If that doesn't do the trick, they may arch their back and raise their tail as a warning. Only if they still feel threatened will they release their spray, which can reach a whopping 12 feet.

Before we review some of the findings from our tracking surveys, we want to extend our congratulations to our trackers, tracking trip leaders, and greater tracking community that came out for our CyberTracker Track and Sign Evaluation! For two days, participants were taken to various locations in Mt Hood National Forest and asked questions about the track and sign found on the landscape, such as: who made this track or sign? how was this animal moving? what was the gender of this animal?
​
​At the end of the weekend, everyone who participated received internationally recognized wildlife tracking certification! Six out of ten participants even received Level 3 Certification! Thank you to David Moskowitz for leading the evaluation on behalf of CyberTracker, and everyone who came out to share their knowledge, perspectives, and tracking skills with us - we are truly impressed by our community!
​
We found a lot of great tracks and sign, and here are some of the highlights from the course:

It's been a great month for our tracking surveys, too! This February we hosted our annual overnight tracking trip in the Tilly Jane area.

The group followed animal trails by day before setting up snow shelters and camping under the clear skies of a full moon. The conditions for a great time could not have been better!

Tracking surveys have also been finding a lot of great track and sign. One of the most common signs on the winter landscape is snowshoe hare. 

We have also been finding a lot of squirrel tracks, and the similar tracks of their carnivorous forest counterpart, weasel! Can you tell the difference between squirrel and weasel in the tracks below?

In our last blog, we discussed how squirrel and hare tracks can be distinguished from one another, but weasel and squirrel can be even more difficult to tough to tell apart. Also commonly found with a bounding gait, weasel tracks can be of similar size, too. One way to tell these apart is by the toes. Squirrels have five toes on their hind feet and four in front; weasels have five toes all around. Squirrels will also have longer toes than claws (for grabbing onto food and tree limbs) and weasels will have longer claws than toes (for grabbing onto their forest prey). Compared to weasels, the first and fifth digit of a squirrel's hind toes are splayed more to the side, while the middle three are kept closer together and pointed more forward, in a 1-3-1 orientation. Weasel toes, on the other hand, will often be more evenly spaced.

Another common track has been the deer mouse. These tracks would be difficult to discern if not for their size! Some of the smallest tracks in the forest, you would be very lucky with excellent conditions if you were able to make out toes in their prints. 

Each of these photos show the same animal performing the same hopping gait. However, the animal is making its way through two different qualities of snow. The first photo shows each foot clearly defined as the animal almost post-holes through snow that has been made more rigid through melting and refreezing, each foot clearly showing where it broke through the surface. In the second photo, we can see the tracks less clearly as the snow hasn't gone through the same weather and is more easily disturbed, yet still light and fluffy enough to pick up a foot drag.

We have also seen a lot of sign from our forest carnivores. One thing all our wildlife have in common is: what goes in, must come out!

Scat can tell us so much about an animal, from genetic information, to diet and individual health - all of which in turn helps us paint a picture not only of their population but of the ecosystem to which the animal belongs. The top two photos belong to two different families of animals, canid and felid. Comparing the two, you can see that canid scat is a bit more twisty than felid scat, which comes out more round and segmented, like Lincoln Logs. Both have bits of hair, which attest to their more carnivorous diet. 

The bottom photo is likely coyote scat, and contains what is likely ungulate fur. Examination of the fur showed that it crimped when pinched between the nails, indicating a hollow hair follicle. Ungulates and polar bears are the only mammals with hollow fur, an adaptation which helps them stay insulated in the cold.

Until next time, we hope you can get out there and enjoy some of the bounty that winter has to offer before it's gone! 

Winter is in full-swing, January brought us deep snows and lots of photos from the Wolverine Tracking Project, and looking ahead, February is shaping up to be a busy month with March not far behind!

See below for news on our camera and tracking surveys. But first, check out some of the classes and events on the calendar.

A big thank you to our volunteers who have been braving the elements to maintain our camera sites! All the fresh snows on Mt Hood have given our camera crews a lot of opportunity for snowshoeing, digging cameras out of the snow, and bringing back some great photos! We've captured a few winter photos like this (below): 

However, thanks to our volunteers braving the elements, we have also detected a lot of wildlife. When the heavy snows weren't burying our cameras, which were originally installed about five and a half feet up a tree, they were making some cameras appear to be at ground level. The result? These wonderful close-ups:

Snow-level cameras also detected some other animals, which make up our marten's carnivorous diet: 

The fresh tracks of the deer mouse show it's hopping gait - though much smaller, it is very similar to the trail a snowshoe hare would leave: small front feet landing first and the larger, more powerful hind feet landing second just ahead of the front feet.

We also detected an up-close and candid portrait of another target species: the Sierra Nevada red fox!

Again, you can see the tracks of this montane fox in the snow. With a meandering trail like this and nose to the ground, it's not hard to assume this fox is hunting. Rodents often burrow into the snow, using the insulating layer as protection from predators and the cold. 

These many visits from these rare, native foxes help us understand their habitat use. We have also collected a few viable hair samples from some of these sites. Like scat samples, hair samples may help give us important genetic information to help us understand their population history, genetic diversity, and habitat connectivity. Hair samples are collected on wire brushes, which are attached to the black belt on the tree just under the bait. 

Our region is home to three kinds of montane fox, the Sierra Nevada red fox (Vulpes vulpes necator) in the Oregon Cascades and Sierras, the Cascade red fox (V.v. cascadensis) found in the Cascades north of the Columbia River, and the Rocky Mountain red fox (V.v. macroura) who are native to northeast Oregon. And, just this week, it was announced that there is a population of Rocky Mountain red fox living near Bend, and likely has been in this area for some time! Just like the Sierra Nevada red fox in our backyard, the montane fox can be elusive and difficult to study, even when they are right under our nose.

Other recent visitors include the ever-present coyote.

We've also detected a few bobcat: 

The bobcat on the right (or bottom), is difficult to make out. However, this lucky visitor is sporting a freshly caught hare! Bobcats (Lynx rufus) are well-adapted for snowy mountains, and, like foxes, marten, and coyotes, snowshoe hare are a favorite snack. Bobcats often hunt at night, and like the marten, don't let their small size fool you! They can cover 10 feet of ground in one pounce.  

We are more likely to see bobcats on the mountain in the winter than their felid cousin, mountain lion. Mountain lions (Puma concolor) are less adapted to snowy environments than bobcat and are more often detected at lower elevations than where most of our cameras are located. 

Another visitor we don't expect to see in the winter? Black bear. However, our cameras did pick up a bear between snows, a bit later than we would expect to see one.

Bears do not hibernate in the same way as most other animals, like some rodents and reptiles, who lower their body temperature along with their metabolism and sleep throughout the whole winter. Instead, they enter a state called torpor where their metabolism slows down, but their body temperature remains elevated and they are able to wake more easily. They can wake from this sleep-state during winter if the weather warms or they are disturbed, and they may even leave their dens, eating opportunistically if they come across food, but do not tend to venture out for long. Other animals that enter a similar torpor state are raccoons and skunks -  plenty of reasons why it is always good to be aware of your surroundings in the forest! Whether this particular bear is taking a mid-torpor stroll or has yet to enter this state for the winter is hard to say. 

One animal, we are not surprised (but always happy) to see is the black-tailed deer. 

Did you know Oregon is home to four native subspecies of deer? Mt Hood National Forest is home to the Columbian black-tailed deer (Odocoileus hemionus columbianus), a subspecies of mule deer. These deer are found from the coastal ranges to the Cascades, and their range runs from California to northern British Columbia (a sister subspecies, Sitka black-tailed deer, is found in Alaska). Rocky Mountain mule deer (O.h. hemionus), another mule deer subspecies, are also native to Oregon, and they are found on the east side of the Cascades summits, most commonly on the east side of our state - fittingly, their range also includes both the American and Canadian Rockies. Black-tailed deer are a little smaller and darker than mule deer, but both have large, mule-like ears. While mule deer seem to prefer open steppe, black-tailed deer tend to prefer brushy areas of coniferous and mixed-coniferous forests, sticking close to clear cuts and burns for browsing opportunities. 

Oregon is also home to two subspecies of white-tailed deer: the Columbian white-tailed deer (Odocoileus virginianus leucurus) and the Northwest (Idaho) white-tailed deer (O.v. ochrourus). The Columbian white-tailed deer is the most rare deer in Oregon. They only live along the lower Columbia River and Umpqua Basin, and the Columbia River population is a federally protected endangered species. The Northwest white-tailed deer is found in the northeastern corner of our state and has a healthy population. As a species, white-tailed deer grow increasingly more abundant as you move toward the east coast. They can be found from Canada to South America and prefer mixed-deciduous forest types.

In our area, you are most likely to see Columbian black-tailed deer - or if you are lucky, the rare Columbian white-tailed deer. Columbian white-tails have long tails they keep held closely to their bodies, and black-tails have shorter tails held loosely to their bodies. If you head a bit further east, you may see the Northwest white-tails; these are the smallest deer of all and have very wide tails. The antlers of each species are different, too. If the antlers are fully developed, white-tailed deer have one main beam on each antler, with points coming of the main beam; black-tailed deer (and mule deer) will typically have a fork coming off the main beam, with points coming off each branch. Check out ODFW's site to read more about our native deer or watch a video on Columbian black- and white-tailed deer identification.

Almost as copious as deer and as perennial as coyote, are our forest corvids.

Plentiful snows, hearty trackers, and some luck have resulted in some great tracking surveys!

One tracking team encountered three separate bobcat trails:

The track quality on these tracks is great, even with a dusting of snow falling after they were laid. These photos show nice clarity of both the individual tracks and the trail pattern, and you can easily see the characteristic felid shape in these tracks. Compared to canid tracks, the whole of the print is quite circular and the thick, oblong pad is surrounded by four evenly spaced "toe beans." When distinguishing between dog and cat tracks, it's better to pay attention to these characteristics, rather than the presence or lack of claws: while felid claws are retractable (and canids are not), a bobcat or mountain lion can extend its claws for traction - something you may see on, say, a snowy/muddy/icy mountainside. 

Distinguishing bobcat from mountain lion is easy, at least for the adults of the two species: go by size! Under 2.25" diameter is likely bobcat; greater than 2.75" is likely mountain lion.

The two tracks we are seeing the most of are snowshoe hare...

...​and squirrel:

The abundance of hare and squirrel is great news for the bobcat, whose tracks were found above, and the rest of our forest carnivores. The photos above show how similar these two animal's tracks are, both animals having bodies well-suited for bounding along, close to the ground. They can be difficult to discern from one another, but hare will be larger than a squirrel, and hare's tracks often have less definition due to the impressive amount of fur covering their pads and toes. Squirrel tracks are also more uniform and boxy - note how well the feet line up on the bottom set of squirrel photos, compared to the more staggered landing of the hare's front feet.

In our forest, we have two kinds of non-hibernating squirrels: the Northern flying squirrel and the Douglas squirrel. However, it is difficult to tell their tracks apart. One way to tell? If you can follow the trail to the start, there will be a "landing strip" where the flying squirrel hit the ground. If you have clear enough tracks, you may be able to tell that the 5th toe on the hind foot (the "pinky toe") is almost as long as any other toe - that's a flying squirrel, too. Read more squirrel track analysis by David Moskowitz. 

Whether in town or on the mountain, we hope to see you soon!

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. 

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. 

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

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, 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. 

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:

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...  

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, 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? 

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...

...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.

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: ​

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!

​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: 

We've also been seeing quite a few squirrels: 

​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!

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.

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!

Our summer season is winding down, but this time of year is when things really start to heat up for us at Cascadia Wild! Like our friends in the forest, we are busy gathering all our resources together to ensure a great winter survey season.

Perhaps the most exciting news from the past several weeks is the detection of Sierra Nevada red fox! 

Though this site was only up for 5 weeks, we had two separate visits from our target species Vulpes vulpes necator - one of the most rare mammals in North America, and an uncommon sight at our summer cameras! We have been operating under the hypothesis that we see this high-mountain fox at our cameras more frequently in the winter because they are drawn in more by the type of bait we use: in summer months we use commercial, scent bait; in the winter we use an eco-friendly meat bait. However, given this detection, we are now considering that perhaps elevation is key. It's possible that these foxes are only at higher elevations in the summertime, living off the ample mice and golden mantled ground squirrels (see below) on these more barren slopes, following food sources down the mountain as winter sets in. This is something to explore in coming seasons, and testifies to how little we know about this elusive animal. 

We also saw quite a few rolling coyote as well. Like the fox above, not many canids can resist the urge to roll in some nice, stinky bait. Here are a couple sampling the potpourri of Hiawatha Valley Predator (one of our commercial scent baits):

Coyotes can also be stoic. The lean and lanky look of this coyote indicates it could be a juvenile, but with its transitional coat it's hard to tell:

Compare to this coyote, who is a bit ahead of the game with its bushy winter coat:

The red coloration of this coyote is remarkable, and it's suitable camouflage for the pine needles on the ground. Coyotes can be difficult to discern from other canids, like foxes and wolves, especially when they have coloring like this. One giveaway is the tail: coyotes most often have a dark tip on their tail, while red foxes often have a white-tip on their slightly more bushy tail. Though it should be noted that gray foxes, who are rare on our mountain but more common to the south, also have dark-tipped tails, and coyotes can even sometimes have white-tipped tails, so it's best to take in other visual clues to their identification. Another clue: the ears are long and pointed on a coyote, but a fox has more rounded ears (see the photo of Sierra Nevada red fox above for a great ear-comparison). Compared to a wolf, coyotes are smaller, have slender faces with narrower snouts, their legs are more long and thin, and they walk more closely to the ground.

We also had another instance detecting a lucky animal with its dinner:  

This bobcat is carrying what is could be a gray squirrel, not unlike a squirrel seen at the same site just a couple weeks prior. However, with striped skunk also in the area, anything is fair game!

We also detected a bobcat doing something we don't often see: rolling in the bait!

This is a trait much more commonly seen with canids, like the ones above, and is the first time our cameras have caught this from a felid. The reasons behind a cat doing this are likely the same as a dog: to relieve itchy backs, disguise their scent, an/or cover themselves in something that smells so good. 

We also caught a few instances of bobcats scent marking trees, like this one:

And we got to see some photos taken in the daytime, really showing off their distinct markings:

Most of our footage of mountain lions is also at night, but we detect them during the day from time to time, and caught some beautiful shots at one of our eastern sites:

We also detected several instances of another of our common forest predators, the black bear:

This bear, not a strict carnivore by any means, is likely foraging in the vegetation. Like most other animals right now, bears are busy gathering their winter stores. Whereas squirrels stash their stores, bears carry their stores with them.

Bears are thoroughly inquisitive, curious animals, and often spend a good deal of time inspecting sites, like this one seen here smelling both our bait area and the camera. 

One of our summer sites used meat bait, and this was a very popular attractant for the neighborhood bears.

One instance the bear went after the bait, another instance the bear gave up and instead had a good scratch, and a third instance the bear forewent the bait entirely and climbed the tree. Whether the bear climbed the tree to get a better vantage point or was spooked by something in the area, is hard to say. It's possible it could have been spooked by one of the several cattle wandering through these woods:

These cows were also interested in the bait. In the second photo, the lighter cow is holding its mouth open in what is called a Flehmen response - something we haven't seen yet this summer but is common in ungulates like cows, deer, and elk, as well as in felids and bears. This is when an animal curls back its lips and breathes into its mouth, holding the air behind its teeth to better smell an area (read more about Flehmen response here).

The bait was also a strong attractant for a family of deer, the youngest still with their summer spots.

We saw deer at several of our other sites as well, like these two young bucks enjoying some early snow:

For family Cervidae, this is a busy time of year: rut, or mating, season. The soft velvet of buck antlers has been shed, and the hardened antlers are now being put to use. 

For elk, we have passed the peak of rut in Oregon, but it's not uncommon for a second or third rut "wave" to happen around this time of year. Not long after seeing this cow - or female elk - and her calf, we saw the mature bull elk pictured below:

We hope you all are staying warm and having good luck readying your own winter stores while enjoying the changing of the seasons. Until next time!

Summer is cruising along! We hope you are getting out there, picking some berries, counting stars, and enjoying the season to the fullest. Volunteers on our camera and scat teams are getting out there and bringing back invaluable footage and genetic samples of our forest wildlife. Thank you to everyone who has contributed! 

If you're looking for another excuse to get out to the woods, look no further! We'll be at Bark's Summer Base Camp to lead a Tracking Workshop on Sunday, September 1st - come for the day, a few nights, or the full two weeks of camping, workshops, and forest and beaver habitat surveys! Family friendly and FREE. We hope to see you there.

Scat surveys:
Keep the Sierra Nevada red fox scat survey in mind as you head out to the mountain trails this summer!
We're creating quite the stockpile of promising Sierra Nevada red fox scat, as well! Not every survey will collect scat, though, and that is as valuable as genetic information - lack of evidence of their presence is data that reinforces the rarity of this animal - and knowing what areas they are using is as helpful as knowing what areas they are not. Once we have enough samples, we send the samples for analyses to our partner at Cascades Carnivore Project (who is also researching the Cascade red fox, a cousin in the alpine areas north of the Columbia River). Depending on the quantity we collect, the whole process can take a year. The more we collect, the more timely we can get the data analyzed and communicated to researchers and management - and the better data set we will have. 

Wolf survey: We also recently sent off five wolf scat samples to be analyzed by ODFW, and are looking forward to the news! A recent survey also found two new scat samples.
Depending on habitat connectivity, availability of prey, and other dynamics, a wolf pack can have a hunting territory of 50-1000 miles (larger territories commonly found in arctic and subarctic areas). While we know the White River pack is nearby, we are still learning about their territory, and a wolf from that pack or another could decide to venture out and claim new territory at any time. It's a good idea to keep an eye out for their signs, especially on the eastern side of the mountain - we never know where they may end up!

Camera surveys: 
We've now seen footage from all our sites, and have a lot of photos for you, including some firsts of the season - and a first ever for this survey! As usual, we saw a lot of elk, deer, coyote, black bear, a couple mountain lions, and a couple bobcats. We of course saw a lot of Douglas squirrel, a lot of very busy chipmunks, at least one ground squirrel, and a few handfuls of unidentifiable rodents, but the star rodent this time was the largest member of the family Sciuridae, the yellow-bellied marmot! 

Speaking of Mustelidae (the weasel family, of which wolverines are a part), we also caught sight of the first weasel of the summer! 

​This lithe and well-camouflaged animal has a unique, identifiable characteristic that sets it apart from other mammals of its size: a long, black-tipped tail which appropriately lends to its name of 'long-tailed weasel.' We always enjoy finding this voracious rodent-hunter on our cameras. 

We also saw our first sooty grouse of the season at the same site (lower left corner).

Like other ground birds, a grouse is always a good sign for our forest carnivores like this bobcat, seemingly hot on its trail.

This other bobcat was very interested in the bait belt itself - but not the bait. Perhaps it was more interested in our human-scent from the camera setup than the canine-scent bait under the log; indeed, one of these two may present more danger than the other.

A fellow feline who rightly fears no animal, hominids included, this mountain lion took a moment of repose at our bait log...

...while another mountain lion was caught on the prowl.

We saw many black bear​, like this one with its black and cinnamon coloration.

This bear visited a few times, and it really enjoyed using the camera tree as a scratching post, leaving us with quite a few pictures of the back of its head.

Two cubs of the year were caught at another site, though rarely on-camera at the same time. The mother, though (top background), was never far behind.

Meanwhile, another one of our cameras captured this very lucky coyote! 

While the coyotes have seemed to move on from this site, for now at least, we did see a lot more hare:

More good news for our forest carnivores, a lot of members of the family Cervidae! Specifically, deer and elk.

The photos of this buck displays its summer velvet wonderfully. The antlers of a mature, well-fed and healthy buck can grow up to 1/4 of an inch a day. For bull elk, antlers can grow almost an inch a day. When velvet is present, the antlers are soft and susceptible to damage, and this is part of the reason why bulls and bucks will tend to stick to a smaller territory, with other males. The velvet sheds when the bone begins to set, about mid- to late-September, just in time for them to roam.

We didn't see too many bull elk this time, but we did see quite a few herds of cows and calves.

We also saw two elk that were tagged and collared...

And were treated to some beautiful photographs of a very curious elk! Hello! 

We have one more first of the season to share with you, the raccoon: 

If you live in a city, chances are you've seen one of these recently. Though more common to see in urban areas, they are still woodland creatures. Like coyotes and other fauna that easily transition to urban areas, they are highly adaptable to their environment. Their presence as scavengers and hunters is always a good sign, and it's always encouraging to see diversity in the forest.

Thanks for reading. We'll be back with more updates soon! 

Our cameras have picked up something a bit uncommon and special to see this summer: juvenile coyotes!

Again, notice the smooth, light coat of a first-year coyote and the lighter frame. Given that juveniles are not ready to hunt on their own at this point, we imagine that it is looking behind for its partner.

What does this mean for the ecosystem?
While perhaps not quite as exciting as the recent videos of the six new wolf pups of the White River wolf pack or the three new pups of the Lassen wolf pack (definitely worth watching if you haven’t), the presence of coyotes and their seemingly abundant offspring indicates that the underlying ecosystem is healthy. What’s more, it could support the growing wolf packs nearby. However, this may come with some food competition and displacement for the coyotes - a coyote will avoid a wolf for the same reasons a fox will avoid a coyote. Luckily, coyotes are timid yet resourceful scavengers and excellent hunters, and their adaptability enables them to survive in environments that wolves cannot, including suburban and urban areas, and enables them to hunt anytime of day or night, allowing crepuscular wolves to use the same territory during dawn or dusk.

Whether we'll see wolves in this area, only time will tell, but in the meantime, these healthy, reproductive carnivores tell a story of a healthy environment that is capable of supporting diverse life. 

Our previous blog post has been corrected to account for an error: a turkey vulture was identified as a turkey! We thought it might be interesting to see a comparison of a turkey (left) with a turkey vulture (right):

Often, factors conspire to make identification difficult. We may only get one, blurry shot of an animal as it zips through a site, or high contrast lighting conditions can make things tricky. And, like comparing the Douglas and Western gray squirrels or rabbits and hares in low photo conditions, similarities can make an ID tricky. Both birds are equivalent size with bald, featherless heads. However, female or juvenile turkeys like the one above are easier to differentiate since they are more slender and upright than a turkey vulture - the long legs and neck and larger size also set turkeys apart from other ground birds like pheasant and grouse. Also note the characteristic speckled coloring of the turkey vulture. Another way to tell? The beak of each animal reflects its diet. Turkeys are foragers that feed off vegetation, insects, and sometimes even lizards and so have more slender beaks, while turkey vultures have sturdier beaks to suit their scavenger diet, one that includes insects, berries, and so on, too, but is primarily focused on carrion. While both birds are an indicator of a healthy ecosystem, they each play different roles. Read more about turkey vultures and turkeys.

That's all for now, and we're looking forward to seeing what the next few weeks bring in!
​Until next time: take care, and thanks for being a part of our community!
