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!

Rain in the valley, snow on the mountain, and an undeniable bite to the wind!
Winter is just around the corner. Much of the forest is settling in for the long seasonal slumber. The trees and perennials are steadfastly storing their summer bounty below ground, seeds are stored away for spring growth, and animals are changing their behaviors in preparation for the snow.
Whether you are one to spend these cooler days like black bears and other forest hibernators, tucked away under blankets or by the fire with a book, or if you are one to brave the elements - we hope you are looking forward to the new season as much as we are!

Both our summer camera and scat surveys are coming to an end, but we are still busy collecting photos and genetic samples from the forest. As we transition to winter, we are excited to share some of our final findings from the summer season with you.

The first images we want to share with you are of one of our striking target species, the Sierra Nevada red fox! 

These are some of best Sierra Nevada red foxes photos we have ever received! You can clearly see the red coat of this fox in the morning light, as well as Mt Hood in the background. We have detected Sierra fox at this alpine site consistently throughout the summer, although the photos have so far only been at night when foxes are more active. This camera site has been taken down for the winter, so these images were a wonderful send-off from such a beautiful site. During the winter, we much more commonly detect Sierra foxes below treeline than in the summer, and we hope to get to see this fox again soon! 

We also received many, many photos of coyotes this season, but none quite so investigative as this individual... 

This individual rolled around this rock face for just under a minute. Mammals (from coyotes to bears to ungulates and more) use scent as a way to communicate. Our smelly camera sites provide a great opportunity for communication from rubbing parts of their body or by marking with urine and scat. The most clear kind of scent communication is when the animal is attempting to deposit its own scent on something else, and the animal will roll or rub its scent glands onto a variety of surfaces. Animals will scent mark with all parts of their body, including their backs, necks, heads, and faces.

However, sometimes mammals will also try to get the scent from something else (usually another animal) deposited on itself. When an animal covers itself in the scent left by other animals, this isn't exactly communication. We actually don't know exactly why they do this! But we speculate that this occurs when an animal wants to mask their own scent, perhaps to hide their scent when they hunt prey. We suspect this is what this coyote was doing. Maybe this individual was about to go off and find itself some dinner! 
​
The individual made sure to come check out the camera after they had a thorough roll around. Check out the whole video here.

We also received many images of black bears this past month, including this individual that had a similar reaction to the bait as the coyote.

This bear also seemed intrigued by the bait, but instead of rolling their entire body in it, they rubbed their head against the smell. In general, bears are much more conservative rollers than coyotes. Where a coyote might roll with enthusiasm, a bear might be content with a cheek rub. 

Along with canines and black bears, our cameras also detected some felines, including a mountain lion.

And some bobcats.

Both of these big cats do not hibernate and will continue to hunt throughout the winter. Both cats are generalists, meaning they can prey on a wide variety of animals, so their diet will shift to prey that is more attainable throughout the winter months. While many small mammals such as ground squirrels and marmots hibernate during winter, other mammals such as snowshoe hares and mice stay active - great food for our bobcats, and they are content to stay at higher elevations throughout the winter where this food is plentiful. Ungulates (deer and elk) will also stay active through the winter, though they head to lower elevations where there is more opportunity to forage. Mountain lions, who prefer ungulates over other foods, also follow them down the mountain.

Speaking of ungulates, many deer walked past our cameras. Bucks, does, and fawns all made an appearance. 

For most of the year, elk stay in same sex groups, or groups composed of cows and calves. Throughout the year these herds can get very large, sometimes with more than 200 members. However, from August to early winter dominant bulls will follow groups of cows. These harems are formed during mating season, and will have 5 to 20 cows and one or two bulls. A dominant bull is a  bull that is in their prime, somewhere between about 5-10 years of age. Bulls breeding success will peak at age 8. These bulls will protect their harems from other bulls. Older and younger bulls will stay on the periphery of these large harems or find their own harems closer to winter.

Our cameras also detected some mammals, and a first!! 

For the first time in Cascadia Wild history, a camera detected an American mink! Minks are semi-aquatic and feed on a diet consisting of rodents, fish, frogs, and birds. They are most often nocturnal and will almost always look for food at night. Minks do not hibernate, so this new friend will be looking for food all winter (when they're not bundled up in their burrow!).

Our cameras also detected some of our usual small mammals including skunks, golden-mantled squirrels, western gray squirrels, and a Douglas squirrels. 

The Douglas squirrel (bottom right photo) has a much shorter tail than is expected. Though tails serve a few functions, one of the most important functions of a squirrel tail is balance. Squirrels use their tails for balance as they scamper through the brush or jump from tree to tree. This partly explains why tree squirrels tend to have longer tails than ground squirrels, and flying squirrels tend to have even longer tails than tree squirrels.

It is not unusual for a squirrel to lose part of their tail. Squirrels have many natural predators, such as snakes, hawks, raccoons (and more) who will bite down on a squirrel's tail, and squirrels can also lose part of their tail to snags in trees or fences. When met with a predator or snag, a thin covering of tail skin and muscle can be torn away without life-threatening impacts. ​

Volunteers have been hard at work on scat surveys this month! So far this season, volunteers have collected at least 9 potential wolf scat samples and  15 potential fox scat samples!

Here is some potential wolf scat from a recent Wolf Scat Survey. 

This scat displays the canine characteristics of shape and contents, and it also is indicative of fox scat due to its smaller size: under 1/2" or the size of your pinky.

Both scats, along with the several others that volunteers have collected over the season, are potentially valuable sources of information about these important canine carnivores that call Mt. Hood National Forest home. While the snows on the mountain may have concluded our alpine fox scat surveys, there may still be a few more good weeks of wolf scat surveys left. As we head into winter, though, we will be collecting less scat and transitioning to seeking out tracks. Lots to look forward to!

A big thank you to everyone who made 2019-2020 a success!

Tracking Club met at the end of July for the first time since February, and it was great to get our noses to the dirt again! Tracking Club is an informal gathering for beginners and experts alike; all are welcome. Join us the last Sunday of each month at Oxbow Park.

 Nature Book Club is held online the fourth Tuesday of every month. Participants come together to discuss the ways nature writing shapes our experiences and relationship with the natural world. Our next meeting is August 25 to discuss Rare Bird: Pursuing the Mystery of the Marbled Murrelet by Maria Mudd-Ruth.

While we are eagerly awaiting a time when it is safe to send all our camera crew volunteers to the field, a handful of volunteers have been helping maintain our 16 wildlife cameras stationed around Mt Hood National Forest. Like seasons' past, we have installed cameras to focus on our target species: Sierra Nevada red fox, gray wolf, Pacific marten, and the ever elusive wolverine.

This summer season has delivered a wide range of wildlife, including one of our target species, the Sierra Nevada red fox! 

The Sierra Nevada red fox has been one of our target species since they were detected on our cameras in 2012. We frequently detect Sierra Nevada foxes in the wintertime at our cameras stationed just below the tree-line. We have detected them during the summer as well, just much less frequently. We are lucky to have a couple of detections this summer. These sightings were at high elevation, which is fitting since Sierra Nevada red foxes have only been found above 4,000 ft in Oregon so far, but these sightings occurred even higher than that. This is valuable information for us, because we initially hypothesized that we were more frequently detecting Sierra Nevada red foxes during the winter because they were experiencing food scarcity and therefore would be more drawn to our meat baits. However, now that we have detected individuals at high elevations for two summers in a row, this could suggest that these foxes are migratory and spend the summer months at higher elevation and the winter months at lower elevation.  

Foxes are opportunistic and will eat berries, plants, insects, and even carrion. But the primary diet of Sierra Nevada red foxes is carnivorous and is mainly comprised of small rodents. Because of this, Sierra Nevada red foxes tend to be most active when rodents are: at dusk and during the night. Perhaps that explains why our cameras detected these individuals at night! 

Our largest regular visitor this season has been the black bear. 

Despite their name, not all black bears have a dark black coat. Their coats can range from light brown to jet black and some individuals can even have blonde or white coats! Black bears are more commonly cinnamon, blonde, or brown in the west than other parts of the country - researchers think this might be to help them blend in with the abundant meadows we have out here. However, about 70% of black bear individuals nationwide have black coats. 

Black bears are typically solitary animals, with the exception of occasional social groups or a mother bear and her cub. A cub litter can usually range anywhere from one to four, and cubs will typically stay with their mothers for two years, sometimes longer, until they are ready to be on their own. Here, our cameras spotted a mama and her yearling walking around the site. 

Our feline friend the bobcat walked through our sites on several occasions. 

This cat is named due to its tail, which appears to be "bobbed". Bobcats are elusive and nocturnal, thus are rarely spotted by humans. Luckily our camera's have detected a few individuals this season! 

Another one of our Mt Hood felines, the mountain lion, stopped by.

​While it may look like the mountain lion is smiling for the camera, it is actually performing a flehmen response. This behavior can be identified when a mammal curls back its upper lip and exposed its front teeth. This allows for pheromones or other scents to be transferred to the vomeronasal organ, which is located above the roof of the mouth. A mammal may perform the flehmen response when it's investigating new odors or tastes. This image is particularly cool because the flehmen response is most often observed in ungulates, so observing it in a big cat is a treat!   

One of the most common visitors to our sites are coyotes. 

Coyotes are one of more investigative visitors to our sites, and are often detected sniffing all around the site. Our cameras also often see them marking the site, either by feces, urine, or rubbing. Above are images of coyotes rubbing their backs on the ground, as well as sniffing their surroundings. The last image features a coyote pausing with their paw raised, which is indicative that they were concentrating on something in their area. Perhaps they were looking for the source of what they were sniffing! 

Another common visitor to our sites are black-tailed deer. Now that summer is in full swing, our cameras have been detecting does with their fawns. 

Fawns are characterized by their brown coats with white spots, this pattern helps them camouflage into tall grass and brush. Fawns are born in the late spring and will weigh between 6 and 8 pounds. It is common for a doe to give birth to twins, though a single birth is not unusual. Does and fawns can create family groups which are led by the oldest mother, while bucks will not help raise the fawns and instead create bachelor groups for the summer.

Bucks can be distinguished from does due to their large antlers. Antlers are actually an extension of the deer's skull and are usually only found on male deer. As growth occurs at the tip of the antler, cartilage is added which is later replaced by bone tissue. As the antler is growing, it is covered with a vascular skin called "velvet". The velvet is almost fuzzy in appearance. The velvet supplies oxygen and nutrients to the growing bone. According to a Cornell University Press publication, deer antlers grow faster than any other mammal bone! Once the antler has reached its ultimate size, the velvet is lost and the bone dies. This dead bone is the most mature phase of antler. ​

On average larger than black-tailed deer, our cameras also often detected elk. 

Elk are one of the largest species within the deer family and are one of the largest terrestrial animals in North America. Bulls are distinguished by their their antlers and loud vocalization consisting of screams known as bugling. 

Beloved for their tall ears and endearing hop, rabbits are no strangers to our sites.

Rabbits and hares are common and important prey for larger mammals, such as bobcats, foxes, coyotes, and even birds of prey. They have adapted to moving swiftly through forests to avoid being an easy meal, finding a wide range of plant matter for their own snacking. As a food source for larger carnivores and as avid herbivores themselves, rabbits play an important role in the ecosystem.

The Mt Hood forest is full of a variety of small rodents, and though they have somewhat similar characteristics, each species is physically and behaviorally distinct. This season we have received images of the Douglas squirrel, the northern flying squirrel, the golden-mantled ground squirrel, and the yellow-bellied marmot. Douglas squirrels are tree squirrels with bushy tails, brown coats and tan bellies, though they appear very dark in black and white photos. They are one of the smallest squirrels in Oregon and are active year-round during the daytime. The Northern flying squirrel are also tree squirrels with dark coats, but their bellies are white and their tails are not as bushy; their tails often appear flat in our photos. Weighing under five ounces, they are the smallest tree squirrel in Oregon. Like the Douglas squirrel they are active year-round, except they explore their surroundings during the night. 

 As opposed to tree squirrels, who dwell in trees, ground squirrels spend most of if not all of their time on the ground. In contrast to the Douglas squirrel and Northern flying squirrel, the golden-mantled ground squirrel is, as the name suggests, a ground squirrel. Golden-mantled ground squirrels are active during the daytime in warmer months, they hibernate throughout the winter season. Their body size and markings lead them to be commonly mistaken for chipmunks, however they are distinctive due to their lack of face stripes and singular lateral white stripe bordered by two black striped on each side of their body. ​

Though significantly larger than the previous species, the ​yellow-bellied marmot is also a ground squirrel. Like the golden-mantled ground squirrel they are also winter hibernators and are actually one of Oregon's longest hibernators, resting from as early as July through April or May. They are our states only marmot and one of the largest squirrels in Oregon. They can be identified by their brown or golden coloring, squat legs, and somewhat bushy tail. ​

Striped skunks are omnivorous, meaning they eat both meat and plant matter. Their diet influenced by the seasons: in the warmer months their diet is primarily insectivorous when grasshoppers, beetles, crickets, and other arthropods are abundant. During colder months the switch to a more carnivorous diet and they will eat smaller mammals, hatchlings, and eggs. 

​One of the most exciting detections was of a Greater sandhill crane. 
There are actually two individuals in this photo, can you spot the second one?

This species is Oregon's tallest bird and is characterized by its red crown and white cheek patches, which contrast with its light gray or brown body. There are only a few pairs of sandhill cranes nesting in the east Cascades, and this bird is one of ODFW's Conservation Strategy Species, so this was a very exciting — and lucky — sighting

Members of our gray wolf and Sierra Nevada red fox surveys have been busy hitting the trails and forest service roads to search of our two canid target species. So far, we have 10 probable Sierra fox scat samples and 8 promising gray wolf scat samples! This genetic data is invaluable in helping us learn about the population, native ancestry, and habitat use of these canids. Combined with the long-term data collected on our wildlife camera and winter tracking surveys, the scat surveys help to tell an overall story of the forest ecosystem that these rare carnivores call home. 

Identifying scat can be terribly tricky!
There are some traits common to all canine scat such as 

• Tapered ends 
• Twisted body
• Easy to dent with a stick when fresh
  
• Since canines are omnivores, their scat can contain ​fruit, plant matter, hair, and/or bone 

However, our target canines have more specific characteristics ​

Comparing these two samples, they are similar because are both twisted in shape and contain both hair and plant matter. However, the potential gray wolf scat is larger overall than the potential Sierra Nevada red fox scat.

​For those of you who are unfamiliar, this is what GPS data looks like from our scat surveys. This is a “track” or GPS route from a recent survey. Note the CaW (Cascadia Wild) shout-out!

Thank you to all our volunteers who keep our wildlife surveys going strong and to our community for your valuable support. Until next time, we hope to see you out in the woods and enjoying some PNW sunshine!

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!

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! 

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!
