Northern Bobwhite Quail (Colinus virginianus) are a native North American ground bird that historically ranged across much of the Central and Eastern United States. The species, which thrived when forests were cleared and mixed-use agriculture characterized the Colonial landscape, has suffered dramatic declines in the past century as grassland habitat has been lost to development and industrial agriculture.
