Herons and Egrets: Understanding the Difference

The distinction between “heron” and “egret” is primarily based on traditional naming conventions and visual appearance, particularly plumage color, rather than strict biological classifications. There is no particular set of characters that differentiates one group from the other.

Traditional Naming Conventions:

Historically, the term “egret” has been used to describe members of the Ardeidae family that typically have white plumage, especially those that develop long, decorative plumes “aigrettes” during breeding season, such as the Great Egret and Snowy Egret. In contrast, “heron” is often used for the larger, non-white members of the family.

Exceptions to the Rule:

However, this is not a strict rule, and there are many exceptions. For example:

• The Little Blue Heron is white only as a juvenile, transitioning to a dark gray-blue as an adult.
• The Reddish Egret exhibits both a white color morph and a dark color morph.
• The Great Blue Heron also has a white color morph, as well as individuals with intermediate plumage.

Taxonomic Reality:

From a taxonomic perspective, both herons and egrets belong to the Ardeidae family. Therefore, egrets are, technically, a type of heron, and vice versa. There is no clear-cut scientific division that definitively separates all “herons” from all “egrets.” In fact, the Great Egret (a purely white-plumaged bird) is taxonomically more closely related to the Great Blue Heron than it is to other white-plumaged egrets.

Note: Many people find it tricky to tell the white herons and egrets apart. For help with identification, see my guide: North American White Egrets and Herons: An Identification Guide

Species of Herons, Egrets, and Bitterns in Arkansas

While most North American herons, egrets, and bitterns have been recorded in Arkansas (some as vagrant or accidental), this guide focuses on species whose official range includes the Natural State, as documented by the eBird/Science platform.

Because Arkansas’s wetlands are biodiverse, you will often find herons and egrets sharing these habitats with other bird species. For a complete picture of the state’s avian life, you can explore our dedicated guide to Arkansas’s Ducks, Geese, and Swans, or browse our overview of other Arkansas Wetland Birds, including storks, snipes, ibises, spoonbills, and rails.

Exploring Heron, Egret, and Bittern Habitats

The aquatic ecosystems in Arkansas supports a moderate concentrations of wading birds. While some species are generalists, appearing in almost any roadside ditch or pond, others are specialized to specific habitats. Knowing the habitats wading birds prefer often helps narrow down the identification. These habitats include:

Estuaries: Where freshwater rivers meet the saltwater of the ocean, creating brackish environments. These are highly productive areas, providing abundant food sources. Expect to see a high diversity of egrets and herons, particularly during low tide when foraging is optimal.

Wetlands: Including salt marshes, freshwater marshes, swamps, and pocosins. These areas are vital for filtering water, preventing floods, and providing habitat. These areas attract species that prefer freshwater prey, such as the American Bittern and Green Herons.

Rivers: From slow-moving coastal rivers to faster-flowing Piedmont and mountain rivers. Riverbanks and floodplains offer foraging and nesting sites. Look for herons along riverbanks and in shallow areas, especially during early morning and late evening.

Lakes, Lagoons, and Reservoirs: Including natural lakes and man-made reservoirs that provide open water and shoreline habitats. Look for herons along riverbanks and in shallow areas, especially during early morning and late evening.

Coastal versus Inland Habitats

The coastal habitats: The mix of saltwater and freshwater are particularly productive for these wading birds. Estuaries, where rivers meet the ocean, offer abundant food sources like fish, crabs, and shrimp. Salt marshes, with their shallow waters and dense vegetation, provide ideal foraging and nesting sites.

Inland habitats: While the coast boasts a high concentration of these birds, inland areas also offer valuable habitats. Freshwater lakes, rivers, and wetlands provide essential foraging and nesting sites.

Arkansas Wading Bird Hotspots: Top 5 Locations for Viewing

Arkansas’s aquatic habitats, dominated by the Mississippi River Alluvial Plain and various reservoir systems, support substantial concentrations of herons, egrets, and bitterns. These regional hotspots offer diverse environments perfect for observing the state’s resident and transient wading birds.

Location List

Holla Bend National Wildlife Refuge (NWR): Located in central Arkansas along the Arkansas River. This refuge features extensive river oxbows and managed moist-soil units. It attracts large feeding flocks of Great Egret, Snowy Egret, and numerous Great Blue Herons.

White River National Wildlife Refuge (NWR): Situated in the eastern lowlands, this large refuge preserves vast bottomland hardwood forests and swamps. It is excellent for viewing nesting colonies of Little Blue Herons, Tricolored Herons, and the secretive Yellow-crowned Night-Heron.

Pond Creek National Wildlife Refuge (NWR): Located in southwestern Arkansas near the Red River. The refuge is known for its shallow lakes and wooded wetlands. It provides prime cover for the Least Bittern, Green Heron, and abundant migrating Great Blue Herons.

Lake Dardanelle: This large reservoir in the western half of the state features extensive shorelines and associated riparian zones. It is a reliable spot for year-round Great Blue Herons, and during migration, it hosts numerous Black-crowned Night-Herons and feeding Great Egrets.

Trusten Holder Wildlife Management Area (WMA): Situated in the central part of the state, this WMA has extensive sloughs and backwater areas of the Arkansas River. Look for the camouflaged American Bittern, along with groups of Cattle Egrets near open fields and Little Blue Herons.

Final Remarks:

The State of Arkansas offers plenty of habitats for herons, egrets, and bitterns. This guide has covered the eleven species of herons, egrets, and bitterns known to occur in the State of Arkansas. While some of these species are widespread and familiar, others are more secretive and local, being associated with specific habitat types. We hope this guide enhances your appreciation for these large and ubiquitous birds.
