If they are very local to the field, then the evening of being cut, they are usually out; although sometimes quite spooked by the cutting. The following few nights will draw others in from afar that may have come across it later during their travels. If there is good food to be had, they will show up there when first out. It is however, easier to catch up with them when the field is bare….. amazing how they can disappear in the middle of a rowed up field
