Field-craft tips#
- Never bait or call owls excessively; stay on trails.
- A long lens (500 mm+) keeps a respectful distance.
- Mostly crepuscular: lean on a fast lens, high ISO and stabilisation; keep distance and avoid flash at nests.
- Sightings peak in January, 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.
