Below is the exact lat/lon where I was when I first encountered the bird. It was amidst the thick bulrushes initially, probably only 5-10 yards away. From that point it slowly made its way westward and southward deeper into the marsh. When I left the area around 730 it was still audible, but becoming fainter. My guess (or hope) is that it was "doing the rounds" so may come back around to the parking area where I first detected it at some point. (37.487640, -106.136866) Nathan Pieplow suggests that a crepuscular or nocturnal visit to the refuge may be more successful in detecting the species in general, although as I mentioned I heard it in the 7am timeframe.
