About the Great Blue Heron#
The great blue heron (Ardea herodias) is a large wading bird in the heron family Ardeidae, common near the shores of open water and in wetlands over most of North America and Central America, as well as the Caribbean and the Galápagos Islands. It is a rare vagrant to coastal Spain, the Azores, and areas of far southern Europe. An all-white population found only in the Caribbean and Florida was once treated as a separate species...

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, July, August and September, 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.
