Smaller mammals, such as voles and mice, thrive in grasslands. These smaller mammals serve as prey for raptors such as red-tailed hawks, northern harriers, American kestrels, and various species of owls, all of which use open grasslands as hunting grounds. Songbird and shorebird species use grasslands to rest, nest and feed.
