Field-craft tips#
- Get down to eye level; a long lens with close focus (or an extension tube) helps with small subjects.
- Sightings peak in August, September, October and November, 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.
