Ground-dwelling birds are species that primarily live and nest on or near the ground rather than in trees. They often have adaptations that help them thrive in their terrestrial habitats, such as strong legs for running and camouflage plumage for protection against predators. Common examples include quails, pheasants, and ostriches. These birds typically forage for food on the ground, eating seeds, insects, and small plants. Their nesting habits involve creating simple scrapes or shallow depressions in the soil, where they lay their eggs. Ground-dwelling birds play important roles in their ecosystems, contributing to seed dispersal and pest control.
