Focal length needed to frame it#
For a subject about 13 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#
- Superb camouflage — use single-point AF on the eye.
- Trunk-clinging birds sit in shade: watch your shutter speed and use zone AF to avoid focusing on bark.
- Sightings peak in April, which is when you'll have the most chances.
- Tiny subjects: get close with a hide or feeder perch rather than cropping heavily.
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.
