Capybaras rely heavily on their fascinating and diverse vocal repertoire for social interactions. These vocalizations, which range from subtle to loud, serve various purposes within their complex social systems. One of the most distinctive sounds capybaras make is a bark-like alarm call used to warn the group of potential threats. They also produce a variety of clicks, whistles, and purrs to convey different emotions and intentions. Remarkably, capybaras can vocalize both on land and underwater, with underwater sounds being particularly important for maintaining group cohesion while swimming. Young capybaras have their own unique calls, including high-pitched whistles to summon their mothers. Perhaps most intriguing is the capybara's ability to produce infrasonic cries—vocalizations below the range of human hearing. These low-frequency sounds are believed to play a role in long-distance communication between groups. Researchers continue to be captivated by the complexity of capybara vocalizations, which provide valuable insights into animal communication.
