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!
