Focal length needed to frame it#

For a subject about 15 cm long filling a third or half of the frame width horizontally. Small birds demand long lenses and a close approach — a blind or feeder setup helps.

Field-craft tips#

  • Bright colours pop in soft overcast light.
  • Bird-eye AF with continuous focus (AF-C/AI Servo); fill at least a third of the frame.
  • Sightings peak in January, February, March and April, 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.
