Green herons are almost the exact opposite of what many people picture a heron to be: tall, long-legged, long-necked and elegant — as is the familiar great blue heron. Instead, green herons are smaller and more compact, with shorter legs, smaller bills, and shorter necks. They are much more secretive as well, often foraging within the cover of wetland vegetation, in either freshwater or saltwater habitats.

These small wading birds can be opportunistic feeders, but primarily hunt for small fish. In this, green herons are unusual among their family in their method of fishing: they’ve often been observed to bait for fish. Using twigs, feathers, berries or even crusts of bread as lure, the green heron tricks its prey into coming close enough to grab. It may also use live bait, such as mayflies, and even earthworms dug from the mud, according to “The Birds of North America” species account.
