Am currently birding Redwood county and am listening to a Henslow's Sparrow singing its full repertoire. It's 4/10 ths of a mile north of Hwy 14 on Cty 61(on west side of the road). I've also heard Eastern Meadowlark and Upland Sandpiper. This is part of Lamberton WMA. There's a lot of grasslands here.
