Though this video might not look like much, it shows something pretty remarkable. This footage, which we captured this past September on the Kabetogama Peninsula, is the first confirmed observation of lynx kittens in Voyageurs National Park (and one of only a few observations of known lynx reproduction in the Greater Voyageurs Ecosystem). Although lynx have been observed/documented in the park sporadically for several decades, there has never been evidence of kittens in the park (i.e., a breeding population of lynx). As a result, most lynx in and around Voyageurs are likely transitory individuals (predominantly males) roaming large area. From 2000 to 2004, biologists with the National Park Service made a concerted effort to study lynx in the park. They only documented the presence of one male and one female, and concluded “lynx were either transient or present at a low density”. Another study from 2007-2008 in and around Voyageurs National Park using trail cameras and snow tracking did not detect the presence of lynx. However, they noted that there were some sightings of lynx outside of the park with one unconfirmed report of a female lynx with a kitten observed to the west of the park. The researchers concluded that “even though patches of high-density snowshoe hare habitat exist in the Voyageurs National Park area, the low density of snowshoe hares at the landscape level would not support resident lynx”. Based on this research and some subsequent work, researchers with the park concluded in 2015 “it does not appear that there are currently resident lynx”. In fact, the researchers in 2012 concluded: ‘only three confirmed observations of adult lynx have occurred within the boundaries of VNP since 2001”. Obviously, studying these elusive animals in places like Voyageurs has historically been difficult because trail camera technology was not what it is today (or did not exist). However, trail cameras have provided a great tool to observe and understand lynx in places like Voyageurs. Skip forward to today: we now routinely get numerous observations of lynx each year in Voyageurs National Park as well as outside the park. Many observations are likely of the same few individuals wandering around, though, based on physical appearances, it seems we are capturing observations of more than 1 or 2 lynx. That said, in general, our trail camera data generally supports the conclusions of the Voyageurs National Park researchers. Most lynx likely are transient individuals, and certainly lynx are at low densities in and around Voyageurs. Nonetheless, this observation of a lynx with two kittens shows that lynx can reproduce in this area, though such occurrences are likely rare. One observation of reproduction is not evidence of a self-sustaining resident population but it suggests it might be possible. Anyway, this finding just highlights how our trail cameras, which are deployed to study wolves, simultaneously capture rare and valuable data on other wildlife species that have been traditionally difficult to study.

Some incredible footage of two wolves killing a beaver this April in Estonia. Now, you might be wondering: why on earth are we sharing a video captured more than 4,000 miles away on a different continent? The reason is to illustrate that beavers are important prey for wolves in a variety of ecosystems across the Northern Hemisphere. When we share our research on wolf-beaver interactions, folks sometimes think wolves hunting beavers is a unique quirk of the wolves in our area, not something that happens in many other areas. But the reality is, across large expanses of North America and Europe, beavers are important prey. For instance, studies have found that beavers constituted a substantial portion of the diets of wolves in many areas including Poland, Latvia, Lithuania, Belarus, Northwest Territories, Alberta, Manitoba, British Columbia, Quebec, Ontario, and Alaska. Obviously, the extent to which wolves rely on hunting and killing beavers likely depends on many factors such as the size of beaver populations and other prey populations. However, the lack of research on the topic leaves the question unanswered. Indeed, the relationship between wolves and beavers has received very little attention because it is a difficult relationship to study, and because most wolf-prey studies focus on how wolves hunt, kill, and impact socially-important ungulate species like moose, deer, elk, and caribou. For more than a decade, a large focus of our research has been to understand the complex and fascinating relationship between wolves and beavers. Such work is without a doubt the most intensive research ever undertaken on this predator-prey relationship. Although our work has provided many insights, we have many questions to answer still, some that will take many more years to answer. The answers to these questions are not just relevant to our small little corner of Minnesota, but to a large swath of the northern hemisphere where wolves hunt and kill beavers routinely. To continue this research, we need donor support because donors are one of our biggest sources of funding. If you value this kind of research and want it to continue, please make a donation here: Lastly, huge thanks to Janek Joab who captured this incredible footage and allowed us to share it on our social media. Absolutely incredible stuff!

Without a doubt, our best trail camera capture yet: the first documented observation of a cougar with kittens in Minnesota in modern history. Turn up the volume to hear all the vocalizations. The footage, which was captured on March 25, shows a cougar with 3 large kittens while they feed on a deer they killed just south of Voyageurs National Park. We captured this surreal footage because we started a study to understand the survival and mortality patterns of deer in our area this winter. As part of that work, we GPS-collared several deer in the area in January. In late March, we received a mortality signal from a GPS-collared deer and found the carcass buried under a pile of leaves on a hillside—a tell tale sign of feline predation. We suspected it was likely a bobcat but thought, just possibly, it could be a cougar. So we put up two trail cameras on the cached deer carcass and 4 hours later, two cougar kittens returned to the kill. The entire family showed up that evening and spent hours in front of our cameras. In total, we captured 7.3 hr (435 minutes) of video footage of these animals. We will share more footage soon! Huge thanks to the Minnesota Environment and Natural Resources Trust Fund for supporting the Voyageurs Wolf Project and the recent effort to understand deer survival in the area. Their support was critical to this observation—without it, we would never have captured this footage. And huge thanks to the >10,600 donors who have supported our project and enabled us to purchase trail cameras supplies. The cameras (and batteries, SD cards, mounts) we set at this kill were purchased with funds from donations.

Absolutely incredible trail camera capture of a coyote attacking a beaver in Connecticut. You might be wondering: “You study wolves in Minnesota, why are you posting this video from Connecticut?” The reason is because this footage illustrates why beavers are important prey for wolves in many forested areas but not coyotes…even though coyotes inhabit many areas with quite a few beavers. Why is that? The coyote tries for several minutes to kill this beaver but the beaver ultimately escapes. Unfortunately, the video was not captured on video but the beaver with his bloodied tail is on the trail only an hour after being attacked. Ultimately, this beaver is almost as large as the coyote and the coyote struggles to really move the beaver at will because of the beaver's size and strength. The coyote bites the beaver's tail repeatedly but virtually never lands a blow to the beaver's muscular body. Coyotes, unlike wolves, simply do not have the strength and size to routinely kill beavers, especially large adult beavers. Wolves, on the other hand, not only have the strength to yank beavers around but they also have the bite strength to grab the beavers body and deliver crushing blows. Killing beavers is harder than it seems because beavers have no obvious neck or easy place for a predator to latch one. They are just one large furry football-shaped hunk of muscle, which complicate the logistics of killing them with one’s mouth, especially for smaller predators like coyotes. Of course, coyotes and other small predators do occasionally kill beavers, especially smaller beavers, but it is not a common occurrence, and there is little evidence that beavers constitute a large portion of coyote diets. We want to extend our sincere thanks to the Traprock Ridge Land Conservancy in Connecticut for reaching out to us and sharing this incredible footage they captured. And big thanks to them for letting us share the footage with everyone here. Capturing an encounter like this on video is one in a million!

More footage of the first documented cougar family in Minnesota in the past century. Volume up for the full experience. More to come soon! Our goal is to learn as much as we can about these cougars in the coming months. But we could really use some help covering costs associated with this research. For instance, we collected 9 scats at this kill and they are on their way to a lab for genetic analysis to try to get individual genetics and determine what western population the mom and dad originated from. Genetic samples cost ~$55-70 per sample, depending on the type and quality of the sample. Your support helps us cover costs like this, and gives us the ability and resources to study these individuals, and any others out there we might learn of. By donating at the link below, you directly support this research. Plus, the support helps us have the capacity to send in any samples we collect in the coming months.Once we have results, we will share with everyone! Notably, we also analyze the genetic samples from every adult wolf we collar, pup we tag, or dead wolf we come across. That work has been supported ENTIRELY by folks donating to our project, and the results have provided a wealth of information on wolf pack and population dynamics. And this work will only continue if generous folks continue to support our work. E.g., a $70 donation ensures we can get the genetics of a wolf. So please donate to our annual fundraiser to support our research, help us cover these costs, and keep this research going! Donate here:

Probably one of the coolest moments we have had in the field…stumbling upon wolf pups sleeping at the entrance of their den which was a huge old beaver lodge. On this particular day in early May, we were searching clusters of GPS-locations from a collared wolf in this pack to find where it had killed prey. The wolf was a subordinate male wolf and had only spent a few hours on the edge of this beaver meadow so we assumed he was just resting here. I.e., there were no indications, based on the wolf’s movements, that this was a den. We hiked along the meadow edge for a bit and as we got close to where the GPS-locations from the wolf were, an uncollared wolf popped up out of the grass by the lodge about 50 meters away and ran into the forest. That seemed far too coincidental…what are the odds that the GPS-collared wolf had been in this spot a few days ago and now, when we arrive there was a different wolf here. As a result, we immediately started to think the lodge could be a den. We approached the lodge and pulled out our phone to record what we observed. We rounded a side of the lodge, approached the entrance, and we found these 4 pups sounds asleep. What a wild few moments. Of course, we thought this was especially interesting, in part, because the wolves were using a massive beaver lodge—i.e.., the home of one of their primary summer prey—as a den to raise their pups, which then would go onto to hunt and kill beavers as adults.
