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.
