What are carrion crows saying to each other? Answering that question has been Vittorio Baglione and Daniela Canestrari’s mission for decades. Carrion crows (Corvus corone) are especially interesting because they engage in cooperative breeding, where entire families, not just the mother and father, are involved in raising chicks and protecting nests. That requires intricate and nuanced communication between individuals. “They have a very complex society, and they do very complex things together,” Baglione, a professor at the University of León in Spain, told Mongabay in a video interview. “It’s really coordinated behavior and we have answered why they do it, but we want to know how they coordinate and exchange information.” The duo have deployed audio recorders and biologgers in northern Spain to decode crow calls and monitor corresponding behavioral patterns. But as the data piled up, they came across a massive hurdle. “Each microphone lasted for six to seven days,” Canestrari, also a professor at the same university, told Mongabay in a video interview. “We realized we actually have too much data to analyze.” Since 2024, the scientists have collaborated with the Earth Species Project (ESP). A team at the U.S.-based nonprofit has helped them develop artificial intelligence models to categorize crow calls and start building a data set of different call types. Scientists in Spain have collaborated with Earth Species Project to categorize a vast dataset of crow calls that they gathered over the years.
