About the Common Gallinule#

The common gallinule (Gallinula galeata) is a bird in the family Rallidae. It was split from the common moorhen by the American Ornithologists' Union in July 2011. It lives around well-vegetated marshes, ponds, canals, and other wetlands in the Americas.

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 January, February, March, 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.
