Tonight at 6:00 pm, Lars Benson and I saw one and heard two Least Bitterns at the location where Ron Erpelding found them in West Duluth. The birds were in the marsh on the left side (as you go out from the parking spot) ALL the way across the lake, almost at the woods on the far side.
Also at Mud Lake, an American Bittern, several Marsh Wrens, only one Yellow-headed Blackbird, Soras. Dave Benson Duluth
