This small heron of wooded swamps, streams and ponds is rarely found among flocks of other herons. I prefers to forage in secluded locations, stalking small fish, tadpoles and amphibians from a perch just above the water’s surface.
A cryptic bird, Green Heron is usually detected by it’s alarm call, given when flushed. The species is strongly migratory and may turn up almost anywhere.
VOICE Agitated bird often gives a soft clucking sound; flight/alarm call familiar: a piercing skiew! or skow!
- 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.
- They tend to wander after the breeding season is over. Most probably seek more favorable foraging areas and do not travel far. Occasionally some turn up in England and France.
- The Green Heron is part of a complex of small herons that sometimes are considered one species. When lumped, they are called Green-backed Heron. When split, they are the Green Heron, the Striated Heron, and the Galapagos Heron.
- A group of herons has many collective nouns, including a “battery”, “hedge”, “pose”, “rookery”, and “scattering” of herons."
