Field-craft tips#

  • Courtship dances (spring) are best shot at water level from a floating or shoreline hide.
  • Get low to the water for an eye-level perspective; expose for bright plumage to avoid clipped whites.
  • Sightings peak in January, February, March, April, November and December, 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.
