These originated within feral stock in Europe over 100 years ago. The males are entirely dark with a glossy green and
blue shade to them. The females are greenish black. They lay small brown eggs and have an incubation period of 24-25 days.
A favorite variety for release, they display a remarkable ability to survive and reproduce in the wild. Prime habitat consists
of 55-70 % crop fields such as corn, soybean, or small grains. The remainder of the habitat should include some wetlands,
grassland, and woodland or brushy thickets.
