About the Sora#

The sora (Porzana carolina) is a small waterbird of the family Rallidae, sometimes also referred to as the sora rail or sora crake. The genus name Porzana is derived from Venetian terms for small rails, and Carolina refers to the Carolina Colony. "Sora" is probably taken from a Native American language.

Field-craft tips#

  • Rails skulk in reeds — wait at a gap in the vegetation at dawn.
  • Shoot from ground level; game birds flush suddenly, so keep the shutter fast and AF in continuous mode.
  • 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.
