I find that they 'rest' areas instinctively, I guess driven simply by supply or lack thereof of whatever they've been foraging in that area until it has chance to reproduce and become worth foraging again
I have seen the same.
Right now, the area looks much worse. Our hot, dry summers, along with the frequent visits from the chickens have left the grasses looking quite miserable. Come mid-late August, the grass bounces back, and is ready to be enjoyed once again.
Interestingly enough, the adults don’t seem to frequent the area again until autumn. They leave a small window for the juveniles (that are usually around at that point) to feed on the grasses there, while they stick to their forage spots closer to the top of the property
