Around now ruffed grouse start to shuffle and disperse. That means more opportunities, but fewer broods. They should start to bunch up again next month. Blues should be changing where they hang out.
I actually prefer late season grouse. The weather isn't as hard on the dogs, scenting conditions are often better, the leaves are down thus creating better visibility for shots, and the crowds of hunters smaller.
Don't be afraid to get off the road to find them. By now they've had some pressure and often won't be as accommodating when you come upon them in the open.
Rainy days, stay home. Dry days, go out and get them.
