About the Tricolored Heron#
The tricolored heron (Egretta tricolor), formerly known in North America as the Louisiana heron, is a small heron. It is a resident breeder from the Gulf states of the United States and northern Mexico south through Central America and the Caribbean to central Brazil and Peru. There is some post-breeding dispersal to well north of the nesting range.

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 January, February, March, April and December, 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.
