The fazendas are small farms in the middle of the mountains, without running water or electricity, and the Atlantic forest, a landscape very similar to the jungle. María Calvo, after graduating in Biology at the University of Navarra, spent a month in Brazil studying monkeys.

A trip to Cabárceno (Cantabria) awakened the interest of this young Navarrese girl in primates. "When the time came to think about summer internships, I started looking on the Internet for places where research projects on these animals were being carried out," she recalls. "And that's how I found the Centro do pesquisas do Iracambi (Brazil)," he says. "The living conditions were very hard and the only way for those of us who worked there to communicate with the outside world was through the Internet".

"When I discovered the first monkeys some tears escaped me."

Finding the monkeys turned out to be more complicated than expected. "In Iracambi, we knew there were monkeys because we heard about them, but no one had seen them," says María, who took long walks in the bush.

"I couldn't find them either because I wasn't following any methodology. I talked to my tutor, and she suggested I visit the Carathinga Biological Station," he says. Without hesitation, with his backpack over his shoulder, he went there. "When I discovered the first monkeys, a few tears came to my eyes," he confesses.

After a week, he returned to Iracambi to take his knowledge to internship . "I set up the research based on what I learned in Carathinga, but I left with no results. Recently, however, I have heard from a colleague who stayed and apparently they have been able to identify a monkey at Iracambi. It seems that it could be a new species. I am satisfied with that".
