About the Swamp Rabbit#

The swamp rabbit (Sylvilagus aquaticus), or swamp hare, is a large cottontail rabbit found in the swamps and wetlands of the southern United States. Other common names for the swamp rabbit include marsh rabbit and cane-cutter. The common name, along with the species name aquaticus (meaning found in water), are suitable names for a species with a strong preference for wet areas and that will take to the water and swim.

Field-craft tips#

  • Backlit ears at sunrise make classic portraits.
  • Get down to eye level; a long lens with close focus (or an extension tube) helps with small subjects.
  • Sightings peak in April, which is when you'll have the most chances.

Ethics#

  • The welfare of the animal comes first: if it changes its behaviour because of you, you are too close.
  • Stay on trails, respect closures around nests, leks, dens and haul-outs.
  • Avoid playback and baiting in sensitive seasons; never bait predators.
  • Don't share precise locations of rare, nesting or roosting animals publicly.
