Into the local marsh well before shooting light. Got to a promising spot, set out the spread, settled in and began the wait. Managed a nice, fat mallard just after shooting light. Fell so close to the boat it splashed mud on me.
Later, something interesting happened. A heron flew into my spread, settled in, and began working the edges of the marsh. Within 2-3 minutes ducks were buzzing by,circling, starting to decoy....then flare just out of range. Before the heron (and after good lighting), no ducks were interested in anything my spread had to offer; other the original fly-byes in the EARLY morning light.
After the heron left, I waded 25-30 yards from my layout boat to see if I could see what was flaring them. Realized then, that my camo grass was several shades too light. Hand mowed several small islands and covered my boat in local grass to alleviate that issue. Unfortunately, I recognized the problem too late in the day.
Poor camo choice on my part aside, I am now positive that confidence decoys have a place in my spread. Adding one ASAP.
Managed to kill, and loose (looked for a good long while) another mallard while pulling in my spread.
In a marsh somewhere, nowhere near your spot.
