About the American Mink#

The American mink (Neogale vison) is a semiaquatic species of mustelid native to North America, though human introduction has expanded its range to many parts of Europe, Asia, and South America. Because of range expansion, the American mink is classed as a least-concern species by the IUCN. The American mink was formerly thought to be the only extant member of the genus Neovison following the extinction of the sea mink (N. macrodon), but recent studies, followed by...

Field-craft tips#

  • River otters play at the same haul-out spots daily.
  • Get down to eye level; a long lens with close focus (or an extension tube) helps with small subjects.
  • Sightings peak in March, April, July and August, 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.
