- The Green Heron is one of the few tool-using birds. It commonly drops bait onto the surface of the water and grabs the small fish that are attracted. It uses a variety of baits and lures, including crusts of bread, insects, earthworms, twigs, or feathers.
- As is typical for many herons, the Green Heron tends to wander after the breeding season is over. Most wanderers probably seek more favorable foraging areas and do not travel far. But,occasionally some go farther, with individuals going as far as England and France.
- A group of herons has many collective nouns, including "a battery of herons", "a hedge of herons", "a pose of herons", "a rookery of herons", and a "scattering of herons."
