‘Spring Celebration’ at Sherburne Refuge

Celebrate the arrival of spring at Sherburne National Wildlife Refuge on Saturday, May 11.  The day begins with an Early Bird Tour at 7:00 a.m., which will end at approximately 11:00 a.m. Participants will meet at the Mahnomen Trail on Co. Rd. 9 for this car caravan tour. The group will search for migrant songbirds such as warblers and sparrows, as well as raptors, waterfowl and shorebirds. A shorter, more leisurely bird tour will be offered for families from 10:30 a.m. to noon, meeting at Refuge Headquarters.  Bring binoculars, water and cameras. No pre-registration is required.

DNR tagging walleyes at Mille Lacs

Anglers who catch a Mille Lacs Lake walleye with an orange tag on its body can receive a free fishing lure if they return that tag to the Minnesota Department of Natural Resources. The offer is part of a broad effort to better understand the lake’s walleye population. DNR fisheries biologists are in the process of tagging and releasing 20,000 walleye.

A new walleye population estimate will be based on the number of tagged fish captured in survey nets after spawning is completed. The orange tags are labeled “REWARD.” Anglers that catch a fish with such a tag should remove it from the fish, even if the fish is released. Tags should be returned to DNR Fisheries, 1200 Minnesota Ave. S., Aitkin, MN 56431. A fishing lure will be mailed in return.
