Due to the angle of the camera and the placement of the animals, these individuals were hard to identify, but here are a few of our justifications. Both these individuals have large feet and an overall gray, grizzled coat, and the second wolf has a significant amount of black in their coat. While there is overlap between wolves and coyotes in both paw size and coat coloration, coyotes more often display tawny coloration and smaller feet than gray wolves. Furthermore, the second wolf individual has a broader face and smaller ears in proportion to their face than we would expect from a coyote. Even with those justifications, this is still a really hard identification. Determining the differences between coyotes and wolves is difficult and is a skill that benefits from time and practice - if you would like to test your own skills, check out this quiz from ODFW! 

This is Cascadia Wild's fourth detection of gray wolves! Woohoo! Our first detection was in the summer of 2018, where we detected the White River breeding pair. This was one of the preliminary documentations of this pair in Mt. Hood National Forest. In the summer of 2019, we detected two wolves at two different locations. Oregon Department of Fish and Wildlife believes that these were also the White River breeding pair. This most recent detection was on the east side of the forest within areas of known wolf activity of the White River pack, so we can make an educated assumption that these individuals also belong to the White River pack. Furthermore, ODFW has also advised that their coloration is consistent with the other members of the White River pack. This is very exciting news and it confirms that our White River pack is still utilizing the same territory. 

This year we had seven detections of our target species Sierra Nevada red fox at two sites! We detected Sierra fox in both alpine and subalpine habitats. ​

Historically, the majority of our fox detections occur during winter. One previous hypothesis as to why we saw so many more during the winter was that they might be experiencing food scarcity and therefore more drawn to our winter meat baits. However, these numerous summer sightings molded a new working hypothesis - for two summers in a row we have detected Sierra fox at high elevations, which suggests that these foxes may be seasonal migrants, spending the summer months at higher elevation, where there are less trees for us to install our cameras, and descending to somewhat lower elevations during the winter months. We cannot wait to see what new information arises in future seasons! 
 
Along with our target species, we have also had a couple new detections this season!
We have never detected these species on our trail cameras before. 

We detected an ​American mink...

It is exciting to have so many new faces, but we always appreciate visits from our regular crew of Mt. Hood mammals. Documenting a wide variety of wildlife allows us to add to our ever-growing knowledge of the forest.

Some species were recurrent throughout the forest, and we received images of them from around Mt. Hood and the eastern boundary.

Our most frequent visitor by far was deer! Individuals or small herds were detected at 95% of all our camera sites, which means they were present at all but one site. Our camera footage allowed us to watch fawns grow up and antlers mature.

Their ungulate cousin, elk, were also detected on our cameras. They said hello to 8 of our cameras throughout the forest. ​

Another frequent visitor was coyote, who was spotted at 70% of of our sites. Consistent with past years, coyotes were prevalent all over the map. These opportunistic feeders can be found in alpine, subalpine, and montane habitats throughout Mt. Hood National Forest.

One of our favorite individuals this season spent a few minutes rolling around at one of our sites. 

Another regular was a fan favorite... the black bear! 

Let's not forget the rolling cubs! You should really watch those videos, they will brighten your day! 

We also detected a variety of squirrels all over the map, including the Douglas squirrel...

​Mountain lion was only detected on the east side of the forest this season, and only at two sites. This is slightly unusual because mountain lions were detected at 5 different camera sites last summer and 4 different camera sites two summers ago. While we can't draw any concrete conclusions from these observations, cougar distribution will be interesting to track in future summer surveys.

There were a handful of smaller critters who were only detected on the eastern side of the forest, including striped skunks.

We only detected California ground squirrels on the east side of the forest. We do not usually find California ground squirrels or striped skunks close to Mt. Hood, so we expected to detect them in this area.

​We also detected quite a few turkeys!

Besides the Sierra Nevada red fox, there were two species only detected close to Mt. Hood: the yellow-bellied marmot and the raccoon. 

We only detected the yellow-bellied marmot at high elevation. Marmots are only found in alpine environments, or sometimes just at the edge of subalpine. They are adapted to live in this environment, munching on alpine vegetation and burrowing in the talus slopes from the first sign of snow until March-May. ​

This is the only raccoon we detected this summer:

Along with camera data, we also accumulated a mountain of scat throughout the summer. Volunteers on our scat survey teams collect these genetic samples to help add to the narrative about our two target canines: gray wolf and Sierra Nevada red fox. 
​
Members of the Wolf Scat Survey Team surveyed 243 miles and found 10 potential wolf scats on the eastern side of the forest. 
Members of the Fox Scat Survey Team covered 54 miles and found 15 potential Sierra Nevada red fox scat samples, mostly around treeline of Mt. Hood!

The diameter, tapered end, and contents of the scat shown in the photo on the left suggest that this sample is potentially wolf scat. The white-ish hue is due to the scat's age. As wolf scat gets older, it turns from a darker brown to a more chalky white. Even though a scat sample may be older, it is still possible to extract a good amount of DNA for analysis. 

We look forward to seeing if any of the scats are a genetic match to their potential species and, if so, to the information that they can tell us about how the native ancestry, distribution, and habitat use of these two important canids. Our scat surveys will resume next summer, when the snows have cleared from the forest.

But, while the snows are here, the camera survey continues and tracking season begins!

As the first snows blanket Mt. Hood National Forest, a whole new wintry world of wildlife opens up to the Wolverine Tracking Project. While we are just at the start of the winter wildlife camera and tracking season, please enjoy a compilation of species and tracks observed so far, thanks to the efforts of our amazing volunteers. Look forward to more in the coming months!

Snow level can rise several feet very quickly on the mountain, and volunteers anticipate this by gradually raising the height of the bait box so it remains accessible to passing wildlife. 

Always a favorite, several charismatic coyotes interacted with camera sites both east and close to Mt. Hood. 

Coyotes are social and expressive. Always adaptable, coyotes can operate solo, as a mated pair, or as part of a pack. Another great adaptation for winter is their thick coats. In the photo directly above, notice that the snowflakes which have settled on this animal's pelt have not melted, it's insulating properties are an amazing adaptation!

 Cat lovers should love out next charismatic carnivore: bobcat. 

The effect of these glowing eyes, which you may have noticed in photos of your cat or dog, is due to a reflective layer called the tapetum, which gives nocturnal animals night vision by reflecting light back into their retinas. All the better to hunt with!

Bobcat's coats are both beautiful and functional, providing both camouflage and insulating protection. These big cats thrive throughout the winter months due to their thick coats. Their fur can become less brown and more gray during winter which allows them to better camouflage into their surroundings. ​

The heavily furred, large paws of bobcats also help them navigate the snow, kind of like snowshoes! 

Black bears were also an occasional visitor to several of our camera sites. 

Black bears are the only bear species in Oregon so it is very easy for our team to identify their pictures! It won't be long until black bears are in hibernation, so we will enjoy seeing them (from a safe distance) while we can!

Making jokes about weasels and their cousins, which scientists call mustelids, is a must for us at Wolverine Tracking Project (haha).

Though the weasel above is moving so fast the picture is blurred, the long body and dark-tipped tail are both characteristics of long-tailed weasels. ​

A tracker also detected the larger cousin of the weasel: the Pacific marten.

The Pacific marten is one of our two mustelid target species. The other is the wolverine, the largest mustelid cousin. While we are still waiting for wolverine to make a return appearance to Mt. Hood, we are always encouraged by the tracks of marten, who are an indicator of a healthy upper-elevation forest. All mustelids have similar footprints, characterized by five clawed toes and an inverted V-shaped heel pad.

No matter the time of year, it is certain that we will have some lovely photos of cervids (deer and elk, keep an eye out for flying cervids over the holidays!)

This male elk above is referred to as a "spike elk" meaning he has at least one antler without any branching. This is most common of younger males under six years old, although genetic, environmental, and health factors may also play a role in delayed, mature growth. In his prime, his antlers may grow as many as 6 or 7 branches, each with their own tips or "points." Male elk are called bulls, female elk are called cows, and their offspring are called calves.

Snowshoe hares are always entertaining visitors to camera sites and their tracks are seen more frequently by volunteers than almost any other species. 

Although a little difficult to visualize at first, snowshoe hare tracks form a "T" shape. This is due to their bounding gait, where the front feet land and the hind feet follow next, landing just in front of the front feet.

Striped skunks are our next species.

Next we have sightings of several squirrel species.

Western gray squirrels are the largest tree squirrel in Oregon. They are rivaled in size by the California ground squirrel (although the prize for largest ground squirrel in Oregon goes to the marmot!). Similar in appearance the western gray squirrel, the California ground squirrel is not gray but very subtly spotted. 

On the other side of size, Douglas squirrel is one the smallest tree squirrels in Oregon (Northern flying squirrels win for the tiniest tree squirrel). Chipmunks, on the other hand, are even smaller and are the smallest ground squirrels in Oregon. 

The squirrel tracks above belong to one of our non-hibernating squirrels of the upper-elevation forest: Douglas squirrel or Northern flying squirrel. They have a similar trail pattern as a snowshoe hare, thanks to their bounding gait, but they are much, much smaller!

Our only ground bird camera visitor was wild turkey. 

On our tracking surveys, trackers found these great sooty grouse tracks! Sooty grouse and turkeys are both important ground birds for our forest carnivores.

Thank you so much to all our camera crew and tracking teams for venturing out, helping to document the wildlife of Mt. Hood National Forest, and sharing your experiences with us!

Until next time, we thank everyone in the Cascadia Wild Community for their support and wish you all the best in the New Year!

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!

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.

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!

This week we've seen some old favorites and made some new friends.

Camera teams went to Government Camp East, Little Zig Zag, and Yellowjacket East. Our tracking trip explored near Salmon River Meadows. ​

It's March which means it's that time of year for foxes! Breeding season is finishing up around now and come April, anywhere from 2 to 10 pups will come into the world in a cozy den, loyally tended to by both of their parents. ​

We had camera checks at Clear Lake, McCubbins Gulch #1 and #2, and Yellowjacket East. A tracking trip visited Teacup Lake. ​

​

The team at Clear Lake encountered some pretty amazing conditions that might have you drooling or cringing- depending on your preferences of snow sports! Either way, it looks BEAUTIFUL! ​

McCubbins #2 was visited by a coyote, a few deer, and a Douglas squirrel apparently competing for space with a (much larger) western gray squirrel that regularly appears on camera. ​

The tracking trip to Snowbunny found hare, mouse, and multiple bobcat trails and brought back some wonderful photos. ​

We had lots of naughty visitors in our photos this week! Okay... maybe "opportunistic" is a better word. The bait at Alpine made it about two days into the set. ​

before...

...and after!

The bait at Government Camp East made it a bit longer than Alpine, lasting for two weeks. This coyote posed for so many beautiful photos, we suppose we can forgive her. ​

Meadows was not spared... Another thief! And so casual about it, too! ​

Another marten leaving perfect tracks at Meadows. It visited multiple times. 

We had camera checks at Bear Springs Far, Clear Lake, and Government Camp West, plus our intrepid trackers went snow camping near Timberline. Check out what they found, plus hear about a couple upcoming events!

The overnight tracking trip (as well as all the snow in the city!) has us thinking about what we need to do to stay warm  - and gets us thinking of all the different ways the animals in our region are specialized to deal with this winter weather. ​

Coyotes' ability to capitalize on any available resources might be one of their greatest adaptations that serves them through winter. Rodents? Great! Deer? Sounds good! Nuts and berries? Love it! ​

Snowshoe hares have adapted in many ways we are all familiar with, like their extremely large, furry hind feet that keep them up on top of the snow. Additionally, snowshoe hares typically turn white at the beginning of winter. In some areas, however, this change does not occur due to the lack of reliable and consistent snowfall. This is a good thing for these creatures, as their bright white fur would be a dead give-away on a brown, snowless day. ​
