About the Black-crowned Night Heron#

The black-crowned night heron (Nycticorax nycticorax), commonly shortened to just night heron in Eurasia, is a medium-sized heron found throughout a large part of the world, except in the coldest regions and Australasia (where it is replaced by the closely related rufous night heron, with which it has hybridized in the area of contact).

Field-craft tips#

  • White egrets: expose for the whites (−0.7 EV in sun).
  • Breeding plumes are most spectacular in spring.
  • Herons and egrets stand still for long periods — wait for the strike or take-off and use continuous AF.
  • Sightings peak in April, May, June and July, 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.
