News from the Wolverine Tracking Project and more
It's that time of year! A BIG thanks to all of our wonderful summer volunteers who made this season such a smashing success. Summer is a great time for viewing wildlife- we saw animals hunting, foraging, mating, and raising their young! This season has proven to us that theres nothing cuter then a baby bobcat (unless it's a baby bear...or deer). We have a lot of exciting wildlife sightings to share with you- including a sighting of one of our target species (the elusive pacific marten) and a first detection ever for Cascadia Wild (check out the badger below!). So without further ado, lets dive in!
This Pacific marten was our only target species caught on camera this season! That doesn't mean that our other target species aren't out there (Sierra Nevada red fox, gray wolf, wolverine), as evidenced by the scat and tracks shown below! While we have yet to see sight or sign of our namesake, the wolverine, we remain hopeful that they will return to their historic natural range, which includes the Oregon Cascades.
The Pacific marten is considered an indicator species of high-quality, high-elevation old growth coniferous forest. This is because they require lots of connected, complex old growth forest in order to thrive. Downed trees and standing snags, along with thick evergreen canopy, (all elements of complex old growth forest structure) provides excellent hunting and denning opportunities for Pacific marten. When snow falls, they rely on small pockets formed amongst fallen trees for thermoregulation while resting.

Signs of our other target species (Sierra Nevada red fox and grey wolf) were discovered over the summer by our awesome volunteer trackers! While we can't say for sure- the tracks below are likely those of a Sierra Nevada red fox. One way Sierra Nevada red fox tracks can be identified is by their small, linear heel-pad, which can be seen in the top track in this photo. In addition, the shape of the track and the distinct X -shape seen in the negative space tells us that this is a canine track.

Below is a possible Sierra Nevada red fox scat found by one of our volunteer trackers. For red fox, we look for scat that is less than half an inch in diameter, and is twisty and tapered at the end. This scat has a lot of hair in it, which is consistent with a red foxes diet!
Potential Sierra Nevada red fox scat- note the tapered ends and small diameter.
Finally, the scat below likely belongs to our target species the gray wolf. Gray wolf scat can be hard to identify- but like other canines we generally look for scat that is twisted, with tapered ends. We expect gray wolf scat to be significantly larger than coyote or red fox scat.
Potential gray wolf scat- this scat is pretty big, and has lots of fur in it!
We detected lots of coyotes this summer, and I mean lots! This makes sense, since coyotes are the most abundant wild canine in the Pacific Northwest. Coyote are an incredibly adaptable species-as unsettled natural area decreases, coyotes are increasingly found living in urban and suburban areas. While there's nothing quite like watching a coyote strut down the sidewalk at six in the morning, it's a treat to see what they are up to in a more natural setting!
From top to bottom: A coyote pauses on a ridge-line, a coyote rolling near a bait site, a coyote urinating near a bait site, a coyote laying down near a tree, and two coyotes sniffing around one of our camera sites.
We saw coyotes looking majestic on mountaintops, rolling on the forest floor, and marking near our bait sites! Lots of species are drawn to our camera sites due to the funky combination of scents we use as bait. Some- like these coyotes- feel compelled to roll in this stinky mixture or add their own scent to the area by urinating nearby.
We had our first badger detection ever this month! It's not surprising that we haven't had many badger sightings before- the American badger range in Oregon is east of the Cascades, and generally outside our survey area. In addition- badgers are notoriously solitary creatures that spend much of their time in dens underground, which makes this sighting all the more special!

Badgers have been known to engage in mutualistic relationships with coyotes! Many Native tribes in North America have stories of this unlikely friendship between coyote and badger. They have been documented hunting together- coyotes are able to catch prey that badgers chase out of burrows, and badgers catch the prey that coyotes scare underground.
Up next we have the felines! The big cat below is known by many names: mountain lion, cougar, panther, and puma! They are sleek and shy, rarely are they seen by people. This summer we saw mountain lions at only four of our camera sites!
From top to bottom: A mountain lions eyes glow in the night, a muscular mountain lion strides through a camera site.
The other felid found roaming our forests is the bobcat!
A female bobcat and her playful cubs pass by.
This summer we had the joy of watching this little family of bobcats pass by one of our camera sites. Bobcat babies are typically born in May and stay with their mom until fall, although some wait until the following spring to disperse. These kittens are likely just a few months old in this photo, but by the time you're reading this they will be practically grown!
One of our cameras caught this particularly stunning photo of a bobcat cruising through the forest.

We saw some big ol' bears this summer (and some teeny ones too!). Bears were seen at 70% of our sites!
From top to bottom: A black bear walking through a burn area, a bear climbing a tree, a bear looking into the camera, and a female bear seen at night with her two cubs.
We saw bears strolling through burn areas and climbing trees. We saw bears see us (our camera, that is!) and bears with their babies! Black bears breed in the summer months, and then give birth in late January or early February in their den. Contrary to popular belief, bears aren't true hibernators. What they do could be more accurately described as entering a semi-dormant state. Hibernation involves an animal lowering their body temperature and metabolic rate, to the extent that they become unresponsive to outside stimulus. While bears do lower their body temperature and slow metabolic processes while denning, they remain responsive throughout the winter.
Striped skunks made an appearance at several of our sites throughout the summer, typically under the cover of darkness.
From top to bottom: A skunk lifting up his tail, and a skunk walking through the forest during the day.
Skunks are nocturnal, so catching this skunk during the daylight hours was a rare treat!
Our last carnivore is significantly smaller than the rest, and can be easy to miss! Although we had a few sightings of the weasel throughout the summer, they were usually just a blur across the camera site.
A weasel paused on top of a rock in the center of the frame.
Ungulates are a diverse clade of hoofed animals. The ungulates found here in the Pacific Northwest are deer and elk. Deer were seen at 95% of our camera sites this summer.
From top to bottom: a deer and her fawn browsing on herbaceous plants, a buck showing off his gorgeous rack, and a mother deer with her curious fawns.
Elk are the larger of the two ungulate species we find in this region. There are two subspecies of elk found in the Pacific Northwest- Rocky Mountain elk and Roosevelt elk. Roosevelt elk are primarily found in the coastal region and western slopes of the Cascades, while the Rocky Mountain elk are more commonly found east of the Cascade range.
In the top photo, the young bull elk gazes off into the distance. The photo right below shows an older bull. The last photo is of an elk passing by one of our camera sites late last spring.
While a few of our camera sites had small herds of elk pass through, some of the most beautiful shots we captured this summer featured elk on their own. Elk shed their antlers every winter, and regrow them in the spring. Antlers grow at an incredibly fast rate- for elk its about an inch a day! In the first photo, the young bull elks antlers are just starting to come in, and are still covered in velvet. The velvet is dense fur that helps to increase oxygen supply to the antlers. Once the antlers are fully grown, like in the next photo, elk will remove the velvet by rubbing their antlers on trees and vegetation.
Our cameras aren't set up to catch small mammals like these, but that doesn't stop them from making many appearances throughout the summer!
We saw Snowshoe hare, rocking their brown summer coats, at four of our camera sites this summer. In the winter, snowshoe hares coats turn white. This helps them to blend in with the snow, and may also increase the amount of heat they are able to absorb from solar energy.
From top to bottom: A snowshoe hare pauses in the foreground of the photo, video of a snowshoe hare bounding through the forest.
The yellow-bellied marmot is our only marmot species in Oregon. We only detected the yellow-bellied marmot at one high elevation site this summer! East of the Cascades, they can be found at lower elevations as they can live in both montane or arid environments. Marmots are true hibernators, by now they are probably snuggled up in their burrows, not to be seen again until spring!

There are several species of squirrels found in our forests. These curious critters are always up to something!
From top to bottom: A Douglas squirrel climbing a tree, the California ground squirrel gathering some vegetation, the Eastern gray squirrel showing off its fluffy tail, the Northern flying squirrel gliding across the forest floor, and the golden mantle ground squirrel having a snack.
Douglas squirrel, like the one in the first picture, are one of the smallest squirrels in Oregon, Douglas squirrels can be identified by their small size and tan bellies. Up next we have an industrious California ground squirrel. In the colder parts of their range (such as here in the Cascades), California ground squirrels hibernate during the winter, so we don't expect to see many of them in the coming months! The next squirrel is easily identified by its long gray, bushy tail- its the Eastern gray squirrel! The squirrel seen gliding across the forest floor in the next image is the Northern flying squirrel. These little forest friends use a fold of their skin, called the patagium, that connects their hind and forelimbs in order to gracefully glide through the forest. Our final squirrel sighting is the golden mantle ground squirrel! These tiny squirrels look a lot like chipmunks. One easy way to tell them apart is that golden mantle ground squirrels lack face stripes. Check out the chipmunk below for comparison!
A chipmunk perches on a branch next to our trail camera.
See those face stripes? This chipmunk was a frequent visitor at one of our sites, and seemed to really enjoy that particular branch for taking a rest and a snack!
The last of our small mammals is the delightful bushy-tailed woodrat. If you look closely in the picture below, you can see how this critter got its name!

Birds and Bats
We had some amazing bird sightings this summer including raptors, owls, bats and ground birds, along with some more common backyard birds! The raptors below are red-tailed hawks.
From the top: A red-tailed hawk comes in for a landing, showing off their beautiful tail feathers. A red-tailed hawks spread wings can be seen in the second photo.
We only had a couple owl sightings this summer. We typically capture images of owls at night, and they can be hard to make out, but below is a picture of an owl captured during the daytime!
An owl comes in for landing on a fallen log.
Like owls, we only expect to get photos of bats after it's dark. The photo below is our one and only bat detection from this summer!
A blurry bat flies through the night.
We had several turkey sightings over the summer. The picture below is the only time we captured a male turkey strutting.

This was our one and only grouse detection all summer!

We also saw some more common backyard birds out in the woods! Including this raven that landed at one of our camera sites.
This beautiful Stellar's jay stopped by on a sunny day.

Those are the highlights from an incredible summer season! Check back in next month to see what we discover with out winter camera sights and our winter tracking crew!
As winter sets in, the days grow longer, providing more opportunity to enjoy the abundance of the natural world and offering hope for the days to come.

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.

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.
A peaceful picture of a snowshoe hare in the snow.
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!
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!
