Pheasant Opener Pheasant Season opens Mid-October Every Year in South Dakota Mansheim Pheasants is a family farm-ranch operation located in Tripp County, SD near Winner and Gregory. We enjoy sharing the fun of our type of hunting activity with you, and pride ourselves on our farming practices which produce the correct atmosphere for wild pheasants. We are not a preserve. All pheasants are natural wild birds. The Missouri River is only 45 minutes away and is known for its excellent Canadian goose hunting as well as fishing. Grouse are in season, and on occasion we will see deer, fox and coyote. Limited lodging is available. Please bring your own sleeping bags or bedding and towels.
