Today at 12:00, I had an adult Swamp Sparrow in the marsh at Running Deer Natural Area. To get to the spot, take the dirt roadway going straight south from the gate at the bathroom. Marsh is on the right (west).Take this roadway to the south end of the marsh and keep on the split to the right that goes around the marsh. At the southwest corner of the marsh is a waterway the goes under the roadway towards Cottonwood Hollow. Stay focused on the marsh. About 100 feet from this waterway is a group of bare trees/shrubs out in the cattails. The Sparrow was seen from the waterway to the closest group of bare trees/shrubs. It was not initially chipping, but responded to my spishing and came up to the top of the cattails to investigate. After about 2-3 minutes, it went back down and did not come up again.
