The maned wolf, a striking canid native to South America, is known for its distinctive appearance and unique genetic lineage. Beyond its physical traits, it possesses a fascinating array of vocalizations. These sounds offer insight into its behavior and solitary life in the vast grasslands and savannas.
The Signature Roar-Bark
The maned wolf’s most recognized vocalization is the “roar-bark,” an explosive, resonant call that carries over long distances. This sound is often described as a deep, booming bark, distinctly different from typical wolf howls or domestic dog barks. It is emitted in sequences, typically consisting of 5 to 15 individual units, with intervals of 2 to 6 seconds between each sound.
This powerful vocalization can travel up to three kilometers across its open habitat. Both male and female maned wolves produce these calls, which are characterized by a low frequency range, generally between 250 and 1200 Hz. The unique acoustic properties of the roar-bark allow it to effectively penetrate the environment, making the maned wolf more easily detected by sound than by sight.
Other Maned Wolf Sounds
While the roar-bark is its most prominent call, the maned wolf also produces other, more subtle vocalizations. These sounds are typically used during closer interactions, suggesting their role in intimate communication. Such vocalizations include softer growls, whines, and huffs.
These gentler sounds contrast sharply with the loud, far-reaching roar-bark. They may be heard in specific contexts, such as communication between a mother and her pups, or during close-range encounters. Captive maned wolves have been observed to produce at least ten different types of vocalizations, showcasing a broader acoustic repertoire for various social situations.
The Purpose Behind Their Calls
Maned wolf vocalizations serve various communicative functions, particularly for this largely solitary species. The distinctive roar-bark is primarily employed for territorial marking and long-distance communication, helping individuals maintain spacing and advertise their presence across expansive home ranges. This long-range call helps separate individuals of the same sex and allows pair-mates to keep in contact, especially during the breeding season or when they have young.
Maned wolves tend to vocalize more frequently during the first three hours of the night, a period coinciding with their peak activity. Other sounds, such as whines and growls, serve different purposes, including expressing submission, signaling alarm, or maintaining contact within a small group like a family unit. The timing and type of vocalization are influenced by social factors and environmental conditions.
