For authentic security, many meager grassland animals move subterrene into their burrows. Burrows render a safe place to support young and disappear from predators, warmth and bad climate. They also render a place to collect food for the future. Some burrowing mammals even dig to find their feed, which is oftentimes pests, worms or plant roots.
Grassland birds command large, public areas of tallgrass prairie and sedge field. They favor treeless regions because trees render defense for predators, such as falcons, rogues, raccoons, canines, and coyotes. Brown-headed cowbirds are also more prevalent along the banks of forested areas. Hence burrowing animals and ground-dwelling birds common in grasslands.
