Alabama’s river otter record, 264 occurrences, reads like a map of the state’s water: records string along rivers, reservoirs, and coastal wetlands from Madison and Jackson counties in the north down to Baldwin on the coast, with the clear streams of the Sipsey Wilderness among the strongest named sites.

A life spent in the water

An otter makes its living underwater, chasing fish, crayfish, and frogs through rivers, lakes, marshes, and brackish coastal lagoons, then hauling out to rest in a bank den or under a pile of driftwood. It advertises its routes without meaning to: smooth slides worn into muddy banks and scat left conspicuously on logs and rocks mark a stretch of shoreline as otter country. Gulf State Park’s lagoons, the waterways of Tuskegee and Bankhead national forests, and Little River Canyon National Preserve all hold that kind of water.

Most visible in midwinter

Counts crest in January and February, when bankside vegetation lies flat, and again pick up into fall. Otters stay active all year, and winter suits the watcher: the animals travel openly along channels in daylight, and low water concentrates them along the same banks an observer can walk.
