When the ground is bursting with vegetation they frequent the fields rather than the mountains. Wherever she may be she remains there when tracked, except when she is suddenly alarmed at night; in which case she moves off. The animal is so prolific that at the same time she is rearing one litter, she produces another and she is pregnant. The scent of the little leverets is stronger than that of the big ones; for while their limbs are still soft they drag the whole body on the ground.
