Field-craft tips#
- Bison: stay 25 m away (National Park rule).
- Bighorn sheep are often on cliffs — expose for the bright rock.
- Use animal-eye AF; for herds stop down a little so several animals are sharp.
- Sightings peak in July, 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.
