“…Considering the multiple negative effects of wind on signal propagation and reception it is probable that lions actively avoid vocalising during these periods as doing so would result in minimal benefit. Similar avoidance behaviour has been recorded for maned wolves (Rocha et al, 2016) and timber wolves (Joslin, 1967). In addition to the effects of wind speed, our results also indicated significant effects for temperature and absolute humidity with lions showing an apparent preference for vocalising in lower temperatures and higher humidity.…”

Maned wolves (Chrysocyon brachyurus) are monogamous and display biparental care for their young, although adults rarely spend time in close proximity. To better understand vocal interactions of maned wolves over long-distances, we passively recorded >10 months of audio data in the species’ natural habitat and analyzed manual recordings of captive animals, covering the reproductive and non-reproductive seasons. In the natural habitat recordings, we found that maned wolves engage in vocal exchanges (termed interactive sequences) more often during the mating season, suggesting the existence of a partner attraction/reunion/guarding function, and also during the initial parental care period, suggesting communication among caregivers. We analyzed 21 interactive sequences, which were the only instances in which we could distinguish individuals, and found that the individuals interacting differed significantly in their roar-bark parameters, including duration, which also differed between males and females in captivity (male vocalizations were, on average, 0.124 s longer). We also found that interactive sequences in captive animals, involving two or more participants, almost always involved both sexes. These results suggest that acoustic interacting maned wolves are most likely male–female dyads.
