For those that are interested, there are at least two Henslow's sparrows
singing at Richardson Nature Center in Bloomington. I got fairly good
views and a nice recording: http://xeno-canto.org/134237. They were
hanging out in the grasses just across the trail from the dock of the lake
that is labeled 'Turtle Basking Pond' on the trail map.
