These monkies come through my wife's family's estate regularly.
They have a group society of their own where everyone has a particular part to play. The "Old Man" usually sits out in the open attracting attention. The larger males also run about making tons of noise in the opposite direction from the females and their babies. The females and their babies usually track along the inside of forest lines on KEMONO NO MICHI (animal paths).
In the forest behind this house, there are monkey nests where they apparently rest out of site of humans.
