Urban life makes animals bolder, more aggressive across 133 species, analysis finds

AI Insight

A global meta-analysis examining 133 animal species found that urban-dwelling animals consistently display bolder, more aggressive, more exploratory, and more active behaviors compared to their rural counterparts. These behavioral differences appear to be a widespread pattern across diverse species rather than isolated cases, suggesting that urbanization exerts a systematic pressure on animal behavior. The study indicates that city environments may be selectively favoring or inducing certain behavioral traits that help animals adapt to human-dominated landscapes.


Understanding how urbanization shapes animal behavior has important implications for wildlife management, urban planning, and biodiversity conservation, as increasingly bold and aggressive wildlife may affect human-animal coexistence in growing cities. These findings could also inform predictions about which species are likely to thrive or struggle as urban expansion continues globally.


A global analysis has found that urban animals are bolder and more aggressive, exploratory and active than their rural counterparts. The findings are published in the Journal of Animal Ecology.
