Summer Season Review
In footage from this summer that was only retrieved recently, we detected these two gray wolves:
Two gray wolves walk by the trail camera
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...

...and a couple of bats!

Though we have detected grouse in past seasons, we have never captured a moment like this.
See the exposed patch on the side of the neck? Those are the air sacs of a male sooty grouse, presented in their mating display! This individual was seen not long after a female grouse was also detected. Maybe we'll see some juvenile grouselings in this area next summer!

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.
Left to right, top to bottom: A doe looks into the camera, a buck shows off their antlers, a fawn sneaks between a gap in a log, a doe and fawn share a sweet moment
Their ungulate cousin, elk, were also detected on our cameras. They said hello to 8 of our cameras throughout the forest.
Left to right, top to bottom: A cow looks at the camera, a bull walks through a camera site, a cow pauses with her calf and looks back at our trail camera
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.

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

Bobcats visited 7 of our sites. These solitary cats were found in both subalpine and montane habitats.

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

...and the golden mantled ground 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 chipmunks. Chipmunks can be found in alpine, subalpine, and montane forest throughout the map, so it was unusual to only detect them on the eastern boundary.
A chipmunk stand on the very edge of frame
We also detected quite a few turkeys!
Three turkeys explore a camera site
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!
Left: A testable wolf scat; Right: A testable Sierra fox scat.
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!
Winter wildlife surveys begin!
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!
A small sapling is progressively blanketed by snow until only the crown is visible.
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.
Top: A coyote glances at the trail camera, as if unsure.
Middle: A trio of coyotes, yes a trio, sweep through this camera site.
Bottom: A coyote strikes a pose while contemplating that strange odor coming from the bait box.
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.
Top: In this photo, only the reflective eyes of the bobcat are visible at first glance.
Middle: A bobcat almost completely blended into their surroundings.
Bottom: A bobcat sniffs the bait box.
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.
Bobcat footprints in the snow.
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.
Top: A black bear snuffles the ground in front of a trail camera.
Bottom: a black bear walks through the same site.
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).
A weasel bounds through the snow.
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.
Top: Weasel footprints in the snow. Bottom: Weasels are also known to meander, and this one weaseled their way into a little natural nook.
A tracker also detected the larger cousin of the weasel: the Pacific marten.
Left: the trail of a Pacific marten; and Right: the detail of a marten's tracks.
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!)
A spike elk considers the trail camera.
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.
Top: Male deer (bucks) seen close up. Bottom: A herd of female deer (does) traverse a lightly snowed field.

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

Left: a snowshoe hare trail. Right: detail of a snowshoe hare's front and hind tracks.
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.

A camera crew unexpectedly got to see this bright-eyed snowshoe hare in person! It is very unusual to encounter them in broad daylight, and the volunteer kept a respectful distance from the animal while capturing this image. You never knew what you might see when you venture out into nature!
Striped skunks are our next species.
A skunk holds it's lovely striped tail aloft as it passes by.
Next we have sightings of several squirrel species.
Left: A western gray squirrel pauses (left); while a California ground squirrel also takes a moment of repose (right).
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.
Left: An acrobatic Douglas squirrel caught by the camera mid-leap.
Right: A chipmunk, almost impossible to spot at first as it is so well camouflaged against the forest floor.
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.
Squirrel tracks in snow
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!
Happy Winter, Happy Holidays, and Happy (almost) New Year!!
Since our last post, we have transitioned from Fall to Winter, and we have been busy!
Earlier this month, we held our first ever fundraiser, Mystery Tracks, and it was a great success in many ways. Not only did we surpass our fundraising goal, but we had so much fun doing so! We also learned that, regardless of current skillset, there is a tracker in every one of us. Excellent work to all who came out to sleuth some tracks and make this a night for the books! And thank you to Jean’s Farm for hosting, Ecliptic Brewing for the keg, and Steve Engel for the masterful plaster track casts.
We would also like to thank everyone who has donated or become a member this month!
If you're considering making a tax-deductible donation on behalf of yourself or a loved one,
there's still time to donate and help us start off strong in 2020.
As a community-based, volunteer-run organization, each dollar makes a difference, and we could not do this work without you!
We are Cascadia Wild!
Now that we are officially in Winter, the Wolverine Tracking Project winter surveys are in full swing! We are getting a lot of footage back from our camera surveys, and a handful of tracking surveys have also been completed. There’s a lot more ground and many months still to cover, but we are off to a great start and have a great group of volunteers helping out this season. Thank you to everyone who is lending their hands, eyes, and time to help document the wildlife of our national forest.
In case you missed it, we have some big news...
WOLVES IN MT HOOD NATIONAL FOREST!
Gray wolves detected by Wolverine Tracking Project Camera Survey, 2019
Sources at ODFW indicate that these individuals, detected on separate occasions at different sites, could be the breeding pair of the White River wolf pack, who have taken up residency on the Warm Springs Reservation and the eastern edge of Mt Hood National Forest. A target species of the Wolverine Tracking Project, we are interested in how the presence of gray wolves will shape the ecosystem of the lands they chose to call home. In hopes of also helping to define their range, we will continue to keep a lookout for these newcomers with several cameras positioned along the forest boundary. As the pack grows and disperses, or as other wolves move in, we expect to see more of them.
Since the wolf detections above, snows have arrived on our mountain, just in time to greet the season. This means we are seeing a lot more of other kinds of animals at our camera sites, including another of our target species: the Sierra Nevada red fox.
This winter, we have 9 cameras located in the immediate Timberline/Government Camp area and an additional two in the outlying area, all specifically focused on targeting this subspecies, one of the most rare mammals in North America and endemic only to the montane slopes of the Sierras and Cascades south of the Columbia River. As winter sets in, they seem more drawn to our sites than in summer, and frequency of detection increases. This is perhaps due to higher concentrations of red fox at the “lower” elevations of our typical sites (their summer range may include the talus slopes where installing camera traps is more difficult). Or, perhaps they are more drawn to the meat bait in these leaner months. Here we can see video compilation of what looks like two different foxes timidly checking some sites:
In both of these videos, the foxes seem drawn to the meat and fox urine we have baited the tree with, yet they are exercising caution. In the second video, what appears to be the same fox came back at least three times over a course of 9 days. Compared to bears or wolverine, who are both notorious when it comes to getting their paws on food, canids tend to be more hesitant, and our Vulpes vulpes necator here is no exception.
Read more about the Sierra Nevada red fox.
Coyotes inspecting bait sites
Coyotes, almost a guaranteed visitor at many of our locations, can also be cautious when it comes to inspecting bait.
Coyote going for a roll near a bait tree
However, coyotes tend to quickly overcome their hesitation and are just as likely to go for a good roll in, or near, the bait (see above)! Whether marking their territory or perfuming their coats, this is one behavior we can almost always count on from these canids.
Family Felidae are also curious about the smells at a site.
Bobcats inspecting the smells at a site
These bobcats are much less hesitant than their canid counterparts, however, and if they show an interest in the bait will generally directly approach it, sometimes even marking it with their scent before leaving (rubbing, urinating, or even rolling in it in less common instances).
Even deer will check out a bait site:
Two does inspect bait on a tree
Though, as herbivores, deer are not interested in bait as a food source, it is in their interest to know who else may be in an area, and so the site behooves inspection.
Other times, they are just passing through...
Clockwise from top left: a doe casually browses her way through the field of view; two does meander through the snow; a young buck contemplates some snowberries; and a yearling seemingly poses for his portrait.
We've been seeing a lot of family Cervidae this month, which includes both deer and elk. Elk seem to have very little interest in bait, though they do sometimes like to inspect cameras. Elk are seemingly always on the move, seeking out the best sites for grazing and shelter every couple of days.
Female elk (cows) on the move
Like deer, elk are crepuscular. Generally, though not always, elk are found grazing at night in large herds (or harems). A ruminant, elk can graze about 20 pounds of vegetation a day! At daybreak or soon after, elk disperse into smaller groups and bed down in shelter (typically forested areas).
Male elk (bulls) on the move
Male elk, or bulls, will often travel solo this time of year. Late summer to early winter is elk breeding season, or rut, and the mature individuals pictured here are likely in pursuit of a harem.
Other animals who display little caution at sites?
A black bear (left) inspects a snag belt (which collects hair for genetic analysis), and a female bear (sow, right) thoroughly inspects a site with her two cubs of the year (coy).
As mentioned above, bears are well-known for being brazen when it comes to food. More so, they tend to be thoroughly curious. As an apex predator, extreme caution is not a characteristic necessary to their survival, though they seem to take great interest in their surroundings.
Some smaller animals are just as brazen as a bear...
Left to right: mice, Clark's nutcracker, and Canada jays are opportunistic at baited sites.
...while other animals can be troublemakers. In the photos above, a striped skunk of family Mephitidae inspects and disassembles a hair snag belt.
Weasels are often seen at our sites in winter, and they will approach bait fearlessly.
Long tailed weasels passing through our sites
The long-tailed weasels above, however, are not displaying interest in the bait. This could be because there is plentiful food for them, like mice, voles, and even larger animals like rabbits and chipmunks. Closely related to skunks and in the same family as wolverine (Mustelidae), it is not surprising that these animals have a diverse carnivore diet and display little caution.
Some other animals tend to always be oblivious to the bait, like these snowshoe hares, though they often tend to perk up a little for the camera:
Two snowshoe hares seem to pause for a photo mid-bound. One hare is in its winter coat (left) and the other, detected before snowfalls, is still in its summer coat (right).
These members of family Leporidae sport large, snow-defying hind legs and have another helpful adaptation: camouflage. The hare on the right appears to still be wearing its darker summer coat, while the hare on the left has changed its seasonal coloration to match the freshly falling snows. Perfectly timed for the season!
Another fearless, though somewhat rare animal detected by our cameras? A herd of camera crew volunteers!
Camera crew are often seen during site maintenance checks in groups of two to four. The above photo shows a particularly large group at a field training earlier this season. Keep an eye out if you are in the woods this time of year: they are a joyful bunch and we hear it can be contagious.
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:
Snowshoe hare tracks in snow displaying the characteristic cluster of a hopping gait
A helpful hint in identifying this species is to look at the trail pattern: there are four footsteps all together in one area, and another four together following it, indicating hopping. For these hares, the prints in the front of the clusters are actually the back feet, and the prints in the back of the clusters are the front feet. Hares will land with their front feet, followed by their back feet, and they will swing their large back feet forward further than their front, ready to spring into the next bound.
We've also been seeing quite a few squirrels:
Squirrel (likely Douglas squirrel) tracks in snow displaying their characteristic double-register
Here, each print is actually two prints - both the front and back foot stepping in the same spot. This is called a double register.
And we've even found some mice!
Mouse tracks in snow, also displaying the characteristic clusters that indicates hopping
The mouse has the same trail pattern as the hare: hopping, with all four feet coming down in the same area.
One of the more exciting tracking finds so far has been Pacific marten. The Pacific marten is also one of our target species: their presence is an indicator of healthy upper-elevation forest.
Detail of Pacific marten tracks in snow (left) and the meandering trail of a Pacific marten (right)
The trail of the marten can be seen above. Several times it appeared to slow to a walk, pause - perhaps looking around - and often kept to the cover of the small saplings. Marten, another mustelid, are also voracious carnivores and it's possible to imagine it skirting the trees on its meandering path, in search of a vole, deer mouse, or other small animal.
A Canada jay perches on a snowy bough
Occasionally, we even get to see wildlife! A common sight are Canada jays. While we do not keep data on these birds, we do like seeing their familiar faces. Like their Corvid cousins - scrub and Stellar jays, Clark's nutcrackers, crows, ravens, and so on - Canada jays are adaptable, have diverse diets, and are generally regarded as highly intelligent, personable, and sneaky. These characteristics lend them and others in family Corvidae the nickname "Camp Robber."
There are few better ways to spend a winter day than strapped into snowshoes documenting the wildlife in our backyard...
...and enjoying the scenery...
...with a great group of trackers:
Thank you all for being a part of Cascadia Wild, this year, in previous years, and in the years to come!
Until next time...
Happy Solstice! Happy Winter!
Our best wishes to you in the New Year!
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.
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!
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!
This is the first time we have caught one of these giant ground squirrels at our cameras! They tend to live on and build deep burrows in talus slopes or alpine meadows, and, though it's not unheard of, it's a wonder that we would find one in this area, which is high-subalpine. Perhaps this one has recently been displaced or has chosen this sub-alpine forest for its abundant edible mosses, grasses, and wildflowers - favorite snacks of marmots.
These dapper rock chucks are named for their coloring, however, they turn tail and burrow at the slightest onset of cold. One of the longest hibernators in our region, marmots can begin hibernation as early as the end of July/mid August, but usually take the dog days of summer to continue building their winter stores.
The biggest present danger to this marmot is coyotes, but wolverines would also be a formidable foe if they reclaim their historic range.
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.
You can almost see the grin on this content coyote. This behavior could be fulfilling a purpose as simple as a good back-scratch. Or, considering the presence of deer in the area some nights prior, could be a way for the coyote to cover itself in the scent of its prey.
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!
The summer season has come to an end. Thanks to all your help, we were able to get new information on 3 different target species, as well many other carnivores.
A wolf pack is now confirmed to be on the Warm Springs Reservation. They also utilize parts of the Mt Hood National Forest, as seen in the photo below. Now that the pack is established, the questions become: will they be able to survive in the area long term and where will they disperse to next? We now need to keep on eye on the rest of the forest and see where they show up next!
Sierra Nevada Red Fox
Two cameras got Sierra Nevada red fox detections this summer, Lambertson Butte and Meadows West. The photo from Lambertson Butte went unnoticed until recently - the fox passed quickly and only left this one blurry photo. But that is enough!
The Meadows West camera detected two different individuals when it was up last winter, based on their coat color. The pictures this summer could be one of the same individuals.
Here are the two individuals from the winter:
And here's the pictures from this summer:
From the grid of cameras we had in the Meadows area, one tentative conclusion is that these fox prefer the higher elevation locations, at least during the summer.
Marten are known to live in high elevation, closed canopy forest, and their pictures from Lambertson Butte, Newton Upper, Meadows Ski Lift, Meadows West, and Meadows Buildings confirm this. But this summer we also got one unusal sighting - from Lemiti Creek! This site borders the Ollallie Lakes area, where they are known to live, but the site itself is in a young lodgepole pine forest that is still recovering from a severe burn. It has a thick regenerating layer of trees less than 10 ftt tall, but hardly any large trees at all. The camera only picked up one picture before it failed for the rest of the summer. Too bad! It would be great to know more about this individual.
Here's a marten from the camera near Mt Hood Meadows Resort:
And here's the one blurry picture from Lemiti Creek:
Here's the final tally of what we found this summer.
The winner for the greatest number of species goes to Jackpot Meadows, and the winner for the least number of species - but still getting a target species - is tied between Lemiti Creek, Newton Upper, and Meadows Ski Lift.
Having so much information on many different species, for many years, has creeated a great opportunity to detect any changes to the wildlife community now that wolves have moved in. We look forward to continuing the study in the years to come!
Thank you all for a great season!!
THANK YOU to all of our volunteers for making these pictures happen!
