The unexpected visitor was impossible to ignore. A snake had entered a classroom near Colombia’s tropical dry forest. For the teacher and his students, the encounter was exciting, emotional, and a little overwhelming. They had never seen a snake like this before, and its size immediately captured everyone’s attention. What happened next tells a much larger story—not only about one snake, but about how years of conservation education can transform fear into respect and turn a surprising wildlife encounter into a lesson that may last a lifetime. The teacher carefully secured the situation and immediately explained to his students that the snake must not be harmed. It was a wild animal, he told them, and it belonged to the same tropical dry forest that is home to the cotton-top tamarin. Rather than responding with violence, the school contacted Proyecto Tití for assistance so the animal could be handled responsibly. For anyone encountering a snake, the safest response is to keep a respectful distance, move students and bystanders away, and contact trained wildlife professionals. People should never attempt to capture or handle a snake unless they have the appropriate training. In this classroom, the most important lesson was already taking shape: wildlife deserves caution, but it also deserves care. 

Why did the teacher think of Proyecto Tití instead of killing the snake? His answer reflected a relationship built through many years of working together. Proyecto Tití has maintained a strong presence at the school, offering activities that help students understand the cotton-top tamarin, the tropical dry forest, and the many species that share this threatened habitat. The children have responded enthusiastically, but the deepest evidence of that relationship is not found only in what they can recite. It can be seen in what they now choose to do. In the past, the teacher explained, a student who found a wild animal might have wanted to hurt it immediately. Today, the reaction is very different. Students call for help. They find their biology teacher and say, “Teacher, look—a snake!” They have learned to stop, observe, and ask what should be done. That pause is where change lives.

Snakes carry a heavy burden of fear and misunderstanding. For generations, many people have been taught that seeing a snake means it must be killed. The teacher has watched his youngest students begin to reject that automatic response. They understand that respect comes first, whether the animal is a snake, a mammal, a bird, or another forest resident. This shift has spread beyond the students. Other teachers and family members now ask questions. They want to know about the animal and how to respond safely. They talk about the importance of preserving the species that form part of the tropical dry forest—an ecosystem they recognize as threatened, precious, and deeply connected to their own community.

The forest is not a distant idea for this school. A nearby protected forest is well known to students, teachers, and families. Their community lies within its area of influence, close enough that wildlife may sometimes travel beyond the trees and seek shelter in human spaces. The snake in the classroom was therefore not an intruder from an unrelated world. It was a neighbor that had crossed an invisible boundary. Proyecto Tití’s work with the school has helped make that connection visible. Protecting cotton-top tamarins has never meant focusing on a single species in isolation. Cotton-tops depend on a functioning forest, and a functioning forest depends on relationships among countless living things. Trees provide food and pathways. Insects pollinate and recycle nutrients. Birds and mammals move seeds. Predators help regulate animal populations. Even the species people fear or overlook contribute to the balance of the ecosystem.

Snakes are part of that balance. As predators, many snakes help control populations of rodents and other animals. Their ecological role remains important regardless of whether people consider them beautiful, frightening, large, small, dangerous, or harmless. As the teacher told his students, no species is insignificant. Each has a function within the ecosystem. That message is now woven into school life. At the beginning of the academic cycle, the school connects conservation themes with different subject areas. Teachers receive materials that help them incorporate the tropical dry forest, threatened wildlife, and conservation into classroom planning. Natural sciences may lead much of the work, but the responsibility belongs to the entire educational community. Schoolwide celebrations focused on the cotton-top tamarin also invite teachers from other disciplines to participate.

This approach matters because conservation cannot live in a single lesson. It becomes powerful when students encounter it repeatedly—in science, community activities, celebrations, conversations with their families, and real-life moments like the arrival of a snake. Knowledge becomes familiarity. Familiarity becomes empathy. Empathy changes behavior. The teacher’s bond with Proyecto Tití is part of this transformation. Over years of collaboration, he has become more than a participant in conservation activities. He is now someone students trust when wildlife appears. He carries the message forward in his own voice, adapts it to unexpected situations, and demonstrates what respect looks like in practice. His advice to other teachers and communities is simple: respect every species and recognize its biological function. The question should not only be whether an animal is venomous or whether it might cause harm. Safety is essential, but fear should not erase an animal’s value or justify unnecessary cruelty. With distance, expert assistance, and accurate information, communities can protect both people and wildlife. This TamarAnne Tuesday, we celebrate a teacher who chose care, students who chose curiosity, and a partnership that helped make both choices possible. A snake entered a classroom, but it brought with it the voice of the forest. The lesson was clear: protecting the cotton-top tamarin means protecting its home, and protecting that home means respecting all its inhabitants—even the ones that frighten us.

Before we close this story, the teacher wanted to leave a special dedication to his daughter, Danna Paola Hernández—a hope that the values he shares with his students will also live on in the next generation:

“For my daughter, Danna Paola Hernández, with love, in the hope that she will share the same love and care for nature as her father.”
