Field-craft tips#

  • Dead snags are favourite drumming posts.
  • Expose for the bright head patches; forests are dim, so raise ISO before dropping shutter speed.
  • Trunk-clinging birds sit in shade: watch your shutter speed and use zone AF to avoid focusing on bark.
  • Sightings peak in June and 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.
