During mid-day while on a Red Deer hunt, a German Forester set me up to shoot Collared Dove( Ring Tauben) from a blind at a mud hole on a forest road. He knew they "watered" there. Also from time to time, while hunting small game on drive hunts, a flock of doves might fly over and we would shoot( these were more like pigeon size). If they were multi colored we wouldn't shoot, for fear of hitting someone's Homing Pigeon( flying these was fairly popular in the area).
