Herons, egrets, and bitterns are all part of the bird family Ardeidae, which consists of approximately 60 to 72 species across numerous genera. However, heron is often used as a general, catch-all term for the entire family. Herons are exceptionally widespread birds, with species found living on every continent except Antarctica. As aquatic birds, herons tend to nest near wetlands, such as marshes, rivers, lakes, swamps, and estuaries. Although some herons are quite large, the majority are medium-sized.

The relationship occasionally becomes mutualistic when egrets perch directly on the animals to eat ticks and biting flies, providing pest relief to the host.
