Red foxes communicate in a number of ways, one of which is to scent mark with urine. During their breeding season, which is at its peak this month, male fox urine takes on a strong skunk-like odor, detectable by most human noses. These “sign posts” advertise the fox’s presence, its dominance and sexual status to all other red foxes that pass by.
Foxes leave scent marks along the boundary of their territory, as well as within it. Often you will find both urine and scat placed strategically on elevated objects, such as rocks, stumps and vegetation emerging from snow as well as at the intersection of two trails. Both male and female foxes leave scent marks. Researchers have found that when foxes are looking for food, they mark up to 70 times an hour. When just traveling and not hunting, they do not mark as frequently.
