A Long-Term Study with Lasting Impact

Founded in 1988 by Dr. Kay Holekamp, the Mara Hyena Project has produced some of the most comprehensive data ever collected on a wild mammal population. Our team currently studies seven hyena clans in the Maasai Mara National Reserve, Kenya.

From collective behavior, communication, and cognition to development and life history, our research addresses fundamental questions about evolution and adaptation in dynamic environments.

MHP community outreach

Working with Local Communities

The MHP is deeply embedded in the Maasai Mara region. We work alongside Maasai community members, hire Maasai staff and researchers, provide outreach and teaching events at local schools, financially support the education of young Maasai scientists, aim to reduce and resolve human-hyena conflict in the region, and provide workshops and talks on a variety of topics from hyena biology to statistical tools for wildlife monitoring.

Our Outreach Work

Help Us Continue This Work

Long-term field research is expensive to maintain. Your support — whether through direct donation or by adopting a hyena — makes it possible to keep these clans monitored and this science alive.
