Despite their reputation as fierce hunters and carnivores, Wolves seem really like the antioxidant-bomb that is blueberries.
Wolves, renowned as skillful predators, are often associated with their unique hunting skills. However, recent research has revealed an unexpected dietary preference in these creatures – an affinity for blueberries.
In fact, blueberries comprise a surprisingly large portion of their diet. This intriguing discovery was made by the Voyageurs Wolf Project from the University of Minnesota.
This article delves into the fascinating findings of this research project, shedding light on the dietary habits of wolves, their behavioral traits, and the innovative methods used to gather this data.
- The Voyageurs Wolf Project discovered that wolves have a significant affinity for bluebrries.
- Blueberries make up to 83% of the weekly diet of wolf packs during the berry season.
- The discovery was made using GPS tracking devices and cameras to monitor the activities of gray wolves in northern Minnesota.
- Research suggests that wolves might be using berries to meet their pups’ minimum food needs or to help them survive when prey is scarce.
How Their Blueberry Diet Was Discovered
The discovery of the significant role blueberries play in a wolf’s diet was an “accidental” result of research conducted by the Voyageurs Wolf Project from the University of Minnesota.
Using GPS tracking devices and cameras, the researchers monitored the activities of gray wolves in northern Minnesota. They observed wolves foraging for blueberries and even captured rare footage of wolves eating the fruit.
Astonishingly, their research showed that berries could make up to 83% of the weekly diet of wolf packs during the berry season!
The researchers also observed an adult wolf regurgitating blueberries for its pups, a behavior previously undocumented. This observation, along with the fact that wolves were bringing back blueberries from other sites for their pups, emphasized the importance of blueberries in their diet.
The findings suggest that wolves might be using berries to meet their pups’ minimum food needs or to help them survive when prey is scarce. This discovery has reshaped our understanding of the dietary habits of wolves, highlighting their flexibility and opportunistic nature.
Other Findings From the Project
The Voyageurs Wolf Project’s research has unveiled fascinating aspects of wolf behavior.
Their innovative use of technology revealed that wolves are not just hunters of land-based prey but also adept fishers, hunting in shallow streams. Beavers, surprisingly, form a substantial part of their diet, accounting for up to 42% of their intake in certain areas.
The tracking data collected by the project has provided valuable insights into the wolves’ movements. It indicates their adaptability to different environments and their ability to exploit diverse food sources.
This research underscores the complexity and versatility of wolf behavior.
Nutritional Benefits of Blueberries – For Humans and Wolves Alike
Blueberries are a powerhouse of nutrition, packed with a variety of essential vitamins, minerals, and antioxidants.
Blueberries offer a significant nutritional source for wolves (and humans), particularly during the summer months when they form a substantial part of their diet. While the exact nutritional needs of wolves differ from humans, the nutrients found in blueberries likely contribute to their well-being.
Furthermore, blueberries have a high water content. They also have a low glycemic index. This means they can provide a steady supply of energy without causing a spike in blood sugar levels.
In essence, blueberries provide wolves with a valuable, energy-efficient food source that contributes to their dietary diversity and adaptability to their environment.
Providing an Energy Efficiency Advantage
For wolves, consuming blueberries also has an energy efficiency advantage.
Hunting requires a considerable expenditure of energy, from stalking and chasing the prey to the actual kill. In contrast, foraging for blueberries, which grow in abundance and do not run away, requires significantly less energy.
This energy-efficient food source is especially beneficial when other prey animals, such as deer and beavers, may be harder to catch.

How GPS Tracking and Hidden Cameras Are Vital For Research
The Voyageurs Wolf Project employs a combination of GPS tracking and camera technology to gather comprehensive data on the wolf population in the Greater Voyageurs Ecosystem.
Wolves are fitted with GPS collars that collect location data at regular intervals, providing detailed insights into their movements, territories, and behavior patterns. This tracking data allows researchers to identify areas where wolves spend significant time, indicating potential feeding or breeding sites.
In addition to GPS tracking, the project uses strategically placed cameras to visually monitor wolf behavior. These cameras capture rare and valuable footage of wolves in their natural habitat. The footage provides us with a visual record of their activities and interactions.

The Voyageurs Wolf Project
The Voyageurs Wolf Project is a pioneering initiative focused on understanding the summer ecology of wolves in the ecosystem of Minnesota, USA. The project employs cutting-edge technology and rigorous research methods to study the behavior, diet, and interaction of wolves with their environment.
The project also emphasizes outreach and education, aiming to increase public understanding of wolves and their role in the ecosystem. Their work has reshaped our understanding of wolf behavior, highlighting their dietary diversity and adaptability.
Above all, their research continues to underscore the importance of maintaining a balanced ecosystem for the survival and well-being of these fascinating creatures.
Wolves and Their Affinity For Blueberries: Wrapping Up
The Voyageurs Wolf Project has made significant strides in understanding the complex and versatile behavior of wolves, particularly their dietary habits. Additionally, the project’s emphasis on outreach and education has also played a crucial role in reshaping public understanding of wolves and their role in the ecosystem.
The fact that wolves like bluebrries underscores the adaptability of wolves to their environment and their ability to exploit diverse food sources.
As we continue to learn more about wolves, it becomes increasingly clear that they are not just predators, but complex creatures with diverse diets and behaviors that contribute significantly to the health of the ecosystems they inhabit.
