By Tim, founder of Easy Street Markets. I maintain the wildlife database and verify every animal and source myself.

The states with the strongest confirmed populations are Alabama, Arizona, Arkansas, California, Colorado and Connecticut, and 42 more. These are real, verified iNaturalist and GBIF occurrence records, not modeled range estimates.

A small number of states (2) have only a handful of unverified or vagrant records, too few to confirm green herons as an established population there.
