Extreme fighting and vocalisations in Tapirus bairdii: observations from aguadas of Calakmul, social arenas for the species

Researchers have uncovered rare and aggressive behaviors in Baird’s tapir (Tapirus bairdii), including intense fighting and complex vocalizations, challenging the species' reputation for shyness. Over a decade of monitoring in Calakmul Biosphere Reserve, Mexico, revealed that ponds called aguadas serve as social arenas where tapirs engage in serious fights and produce various whistles, likely linked to courtship. These findings shed light on the social dynamics of this endangered Neotropical ungulate, offering insights into the causes of wounds and scars observed in adults. The study highlights the importance of these behaviors for tapir conservation efforts.
