Now in nature: Groundhogs are hibernating, gone from the pastures and roadsides until March. Black bear sows (females) with yearling cubs have found their winter dens by now, about a month later than the unencumbered females. Male bears will wait until mid-December to den.
River otters have begun to breed. White-tailed deer are nearing the end of their rut. Brook and brown trout are beginning to spawn. Sauger fishing is beginning to heat up. Golden and bald eagles are arriving in Tennessee for the winter. The fall migration of ducks and geese is underway; watch for them in their familiar V formations and you may hear them, too, especially the geese.
