Beside a hill burn on island of Mull (so a number of mainland species not present) about 1 mile in from coast, 500 feet above sea level. Spot not frequented by people - or their dogs. Two lots deposited within ten strides of one another. One lot absolutely fresh, faint fishy smell if any discernible scent (though everyone had colds...), other lot seemed a fair bit older. Wellies size 6.
