I read with interest Kathryn Reshetiloff’s Bay Naturalist column, “Red fox’s adaptability to humans helps to make it more widespread” (January-February 2002).
She may have painted their lifestyle in suburbia a little too rosy. After finding a dead fox in our backyard shed a few winters ago, my family and I learned from Animal Control personnel that mange is both common and a frequent cause of death in foxes of Montgomery County, MD. It is a debilitating skin disease that left untreated will lead to a slow and painful death.
The Animal Control personnel suggested it was a natural mechanism for controlling population cycles: When foxes get too abundant, more of them contract mange and the population declines until the disease subsides.
Because mange is so persistent in Montgomery County foxes, I wondered at the time about the possible connection to the ever-widening loss of habitat quantity/quality (from development) in the area.
It would be interesting to learn more about suburban wildlife and their incidences of disease in the Chesapeake area.
