The COVID-19 pandemic brought about unforeseen changes in various aspects of life, including the behavior of zoo animals. A study conducted in 2022 shed light on how primates, including bonobos, chimpanzees, western lowland gorillas, and olive baboons, adapted to the absence of crowds due to lockdown measures. Researchers found that these animals altered their habits in response to the reduced visitor interactions, impacting the time they spent resting and eating.
Impact of Visitor Absence on Primate Welfare
Visitor interactions are considered crucial for the well-being of zoo animals, as they can influence behavior positively or negatively. The absence of crowds provided researchers with a unique opportunity to study the effects of reduced human presence on animal behavior. Primates, known for their cognitive abilities, displayed varying changes in behavior at Twycross Zoo and Knowsley Safari in the UK before and after visitors returned.
During the closure and reopening periods, observations revealed significant shifts in primate behavior, depending on the species. Bonobos and gorillas exhibited reduced solitary time when visitors returned, with gorillas also spending less time resting. Chimpanzees showed increased eating and engagement with their enclosures post-reopening. Olive baboons at the safari park displayed less sexual and dominance behavior in the presence of visitors, opting to interact with visitor cars rather than ranger vehicles.
While the researchers noted behavioral changes in response to visitor presence, determining whether these changes were positive remains a challenge. Stimulating effects were observed in chimpanzees and baboons with the return of visitors, while the decreased solitary time for gorillas and bonobos could be interpreted positively. However, disruptions to the rest patterns of sedentary animals like gorillas suggested potential negative impacts of increased human activity.
The ability of zoo animals to adjust their behavior and enclosure use in response to environmental changes highlights their adaptability. Observations indicated that the animals could manage disruptions caused by visitors, emphasizing the importance of providing environments that support active adaptation for animal welfare. The findings underscore the need for continued research on how visitor numbers affect animal behavior across a broader range of species and over an extended period.
Future Research Directions
As the study concluded, the researchers emphasized the significance of examining the impact of visitor numbers on a wider array of species in zoos and safari parks. Understanding individual variations among animals and the long-term effects of human interactions is essential for promoting animal welfare and informing the design and management of zoological facilities. Continued research in this area will contribute valuable insights into optimizing the well-being of captive wildlife in response to changing environmental conditions.
