Field-craft tips#
- Use 1/2000 s+ and shoot bursts as they surface.
- Boat motion adds blur — keep 1/1000 s minimum and use stabilisation.
- Sightings peak in June, 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.
