To establish the circadian activity of the Red Fox (Vulpes vulpes) and the Stone Marten (Martes foina) in agricultural habitats of Southern Bulgaria a total of 5 camera traps were set in protected area “Maritsa - Parvomay”. Both carnivores demonstrated bimodal nocturnal activity with close or coincident hour intervals. They showed peak activity in the dark and in the twilight, which is usual for areas with strong anthropogenic influence.
