Focal length needed to frame it#

For a subject about 16 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#

Photograph at nest sites or over water where they hunt insects.
Swallows and swifts are the hardest flight subjects — use wide tracking AF and shoot where they repeat a pattern.
Sightings peak in April and May, 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.
