About the Glossy Ibis#

The glossy ibis (Plegadis falcinellus) is a wading bird in the ibis family Threskiornithidae. The scientific name derives from Ancient Greek plegados and Latin, falcis, both meaning "sickle" and referring to the distinctive shape of the bill.

Field-craft tips#

  • Feeding flocks move steadily — track and wait for the head-up moment.
  • Herons and egrets stand still for long periods — wait for the strike or take-off and use continuous AF.
  • 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.
