Which is a common sign of wildlife overpopulation?

Increased roadkill incidents serve as a common sign of wildlife overpopulation. When animal populations grow beyond the carrying capacity of their habitat, they often start to encroach on human spaces in search of food, water, and shelter. This can lead to more frequent interactions with vehicles, resulting in a higher number of roadkill incidents.

As populations increase, animals may venture onto roads more often, leading to collisions and fatalities. The presence of more animals trying to cross roads reflects an imbalance in the local ecosystem and indicates that their natural resources are becoming limited.

On the other hand, while increased feeding in parks may suggest that there are more animals, it does not necessarily indicate overpopulation, as feeding can happen for various reasons, including food availability. Decreased animal sightings might imply that animals are unable to find sufficient resources or that they are adapting their behavior to avoid human interaction, rather than indicating overpopulation. Fewer nests in trees would suggest a declining or stable population, not an overpopulation situation, as more animals typically require more breeding and nesting opportunities.
