Dear Supporters,
We’re thrilled to share an exciting new glimpse into the hidden world of Andean Bears, captured through our ongoing work in Bolivia’s cloud forests. Our field cameras recently recorded a rare and fascinating behavior—two different Andean bears rubbing against the same tree just one day apart!

While we haven’t yet confirmed the age or sex of these individuals, the footage provides a window into the complex social communication system of this elusive and endangered species. Here’s what makes this behavior so special:
Andean Bears Are Solitary but Connected:
Though they live alone and are not territorial, Andean bears communicate by leaving scent marks. They rub their heads, necks, shoulders, and sides against trees and other objects, leaving behind chemical "messages" that other bears revisit over time.
The Height of the Mark Matters:
The level at which a bear rubs may indicate its size or social status, and help others identify a potential mate, family member, or competitor.
"Meeting Trees" as Communication Hubs:
Bears often choose visually distinct trees—like certain conifers—that help preserve their scent for longer. These trees become communication hubs in the forest.
More Than Just Rubbing:
In addition to rubbing, Andean bears may scratch or bite the bark to reinforce their message.
This behavior, rarely observed in the wild, is a beautiful example of how wildlife uses chemical signals to maintain social networks—without ever needing to meet face-to-face.
Your support is what makes this research possible. With your help, we are learning more every day about Andean bear behavior and protecting their fragile habitats through community-based conservation and women-led research.
Thank you for standing with us in safeguarding the future of this incredible species.
With gratitude,
The Women for Conservation Team – Programa Jucumari
