Why do wild boars soften bumps?

Wild boars soften bumps primarily as a natural behavior to forage for food. By rooting in the ground with their snouts, they disturb the soil, allowing them to uncover hidden tubers, roots, and insects. This behavior also helps in creating softer ground, making it easier for them to access nutritious food sources. Additionally, softening the terrain can create a more comfortable environment for resting and nesting.
