Excerpt from this article :
Making their American debut in the late-nineteenth century, these European imports were first released in Washington and California but are now found in huntable numbers in about a dozen Western and Midwestern states and most Canadian provinces. The first birds released in this country came from Hungary, so the gray partridge is also commonly known as Hungarian partridge, or Hun.
Gray partridge, which grow to just over a foot long and weigh about three-quarters of a pound, eat both cultivated grains and a variety of weed seeds, as well as clover and other green, leafy material. As is the case with pheasants and other upland bird species, young partridge feed heavily on crickets, ants, grasshoppers and other insects. They often inhabit the “margins” where agricultural fields and native shrub-steppe habitat meet. Classic Hungarian partridge country might be a field of corn or wheat stubble bordered or intersected by a couple of brushy draws or a gently-sloping hillside dotted with sagebrush. A small stream, pond or wetland nearby would likely make such a spot even more attractive to a covey of Huns.
