The herons and egrets of the United States include some of our most recognizable wetland birds. They range from towering Great Blue Herons to tiny Least Bitterns hidden among the reeds.

Although their names differ, herons, egrets, night-herons, and bitterns all belong to the heron family, Ardeidae. This guide covers 12 familiar species regularly found across the United States.

Use the photographs and quick identification clues below to compare each bird. Then follow the links for detailed information about behavior, diet, habitat, nesting, and conservation.

How to Identify Herons and Egrets

At first glance, many wading birds can look remarkably similar. However, a few key features usually reveal the bird’s identity.

Look closely at:

• Overall size and body shape
• Plumage color
• Bill color and thickness
• Leg and foot color
• Neck length and posture
• Feeding behavior
• Wetland or upland habitat

Even an all-white bird becomes easier to identify once you check its bill, legs, and feet.

Great Blue Heron

The Great Blue Heron is the easiest species on this list to identify by size alone. It stands about four feet tall, with extremely long legs, a long S-shaped neck, and a heavy, dagger-like bill.

Adults have a blue-gray body, white face, black stripe above the eye, and dark feathers extending from the back of the head. Rusty coloring may appear on the shoulders, thighs, and lower neck.

Do not let the name fool you. From a distance, the bird may look gray rather than blue. It is much larger and paler than a Tricolored Heron or Little Blue Heron. In flight, it folds its neck against its body while its long legs trail behind.

Best identification clues: Enormous size, blue-gray body, white face, black crown stripe, and heavy yellow-orange bill.

Great Egret

The Great Egret is a tall, slender white heron with a long neck and pointed yellow bill. Its legs and feet are black, creating a strong contrast with its white plumage.

It is smaller and more delicate than a Great Blue Heron but considerably larger than a Snowy Egret. Great Egrets usually hunt with slow, deliberate steps or stand motionless while watching for prey.

During breeding season, adults grow long, flowing plumes across the back. The bare skin between the bill and eyes may also become brighter green.

A large white bird with a yellow bill and black legs is almost always a Great Egret.

Best identification clues: Large size, white plumage, long yellow bill, and completely black legs and feet.

Snowy Egret

The Snowy Egret is smaller and more energetic than the Great Egret. It has a slim black bill, black legs, and bright yellow feet that look like tiny golden slippers.

Snowy Egrets rarely stand still for long while feeding. They may run through shallow water, stir the bottom with their feet, flick their wings, or suddenly change direction while chasing fish.

The yellow feet are the best clue, although they may disappear beneath muddy or murky water. When the feet are hidden, look for the thin black bill and smaller body.

A juvenile Little Blue Heron is also white. However, it has a pale grayish bill with a dark tip and dull greenish legs rather than a completely black bill and bright yellow feet.

Best identification clues: Small white body, black bill, black legs, yellow feet, and active feeding style.

Western Cattle-Egret

The Western Cattle-Egret has a shorter neck, shorter legs, and more compact body than other white egrets. Its yellow bill is noticeably shorter and thicker than the long, narrow bills of Great and Snowy Egrets.

Nonbreeding adults are mostly white. During breeding season, they develop golden-orange feathers across the crown, chest, and back.

Habitat is often the easiest clue. Western Cattle-Egrets commonly forage in fields, pastures, roadsides, and recently mowed grass. They frequently follow cattle, horses, tractors, or lawn equipment that stir insects from the vegetation.

A short, stocky white egret walking through a pasture is far more likely to be a Western Cattle-Egret than a Great or Snowy Egret.

Best identification clues: Compact shape, short yellow bill, shorter legs, and preference for fields and grazing animals.

Little Blue Heron

Adult Little Blue Herons have dark slate-blue bodies with rich purple or maroon coloring across the head and neck. Their bills are pale blue-gray near the face and become darker toward the tip.

Adults are about the same size as Snowy Egrets. They are much smaller and darker than Great Blue Herons. Unlike Tricolored Herons, Little Blue Herons do not have a white belly or bold white stripe down the neck.

Young Little Blue Herons look entirely different. Juveniles are white and are often mistaken for Snowy Egrets. Look for the juvenile Little Blue Heron’s grayish, dark-tipped bill and greenish-yellow legs. As the bird matures, scattered blue feathers create a patchy blue-and-white appearance.

Best identification clues: Slate-blue adult plumage, purple neck, two-toned bill, or white juvenile with greenish legs.

Tricolored Heron

The Tricolored Heron is a slim, medium-sized heron with a blue-gray back, dark neck, and bright white belly. A narrow white stripe usually runs down the front of the neck.

That white belly is the most reliable way to separate it from an adult Little Blue Heron or dark-morph Reddish Egret. Both of those birds have darker underparts.

Tricolored Herons are larger than Snowy Egrets but much smaller and more slender than Great Blue Herons. They often forage in open shallow water using quick steps, sudden turns, wing flicks, and short dashes.

Young birds have rusty coloring on the neck and shoulders, but the pale belly remains an important clue.

Best identification clues: Slender shape, dark blue-gray upperparts, white belly, and white stripe down the neck.

Reddish Egret

The Reddish Egret is a medium-to-large coastal heron known for its shaggy feathers and wildly energetic feeding style.

Dark-morph adults have blue-gray bodies with reddish-brown heads and necks. White-morph birds are almost completely white, making them easy to confuse with Great Egrets and other white herons.

In either color form, look for a pink bill with a black tip, blue-gray legs, shaggy head and neck feathers, and an active hunting style. Reddish Egrets frequently run, leap, spin, raise their wings, and create patches of shade while pursuing fish.

They are larger than Snowy Egrets but smaller than Great Egrets. They are also strongly associated with shallow coastal lagoons, tidal flats, and saltwater environments.

Best identification clues: Pink-and-black bill, blue-gray legs, shaggy feathers, coastal habitat, and dancing feeding behavior.

Green Heron

The Green Heron is a small, compact bird with short legs, a thick neck, and a dark cap. Adults have deep chestnut-colored necks and dark greenish backs that may look blue-black in poor light.

Their hunched posture can make them appear almost neckless. However, a Green Heron can suddenly extend its neck much farther than expected when striking at prey.

Green Herons usually remain close to cover. Look for them along wooded ponds, narrow creeks, marsh edges, drainage ditches, and shorelines with overhanging branches.

They are smaller and more colorful than juvenile night-herons. They also lack the buff wing patches and boldly striped neck of a Least Bittern.

Best identification clues: Small stocky body, chestnut neck, dark green back, yellowish legs, and crouched shoreline posture.

Black-Crowned Night-Heron

The Black-crowned Night-Heron has a stocky body, short neck, thick bill, and relatively short legs. Adults have pale gray wings, whitish underparts, a black back and crown, and striking red eyes.

They often rest in trees or dense vegetation during the day. Around sunset, they become more active and fly toward feeding areas with slow, steady wingbeats.

Juveniles are brown with bold pale spots across the wings. Their streaked underparts and spotted backs can cause confusion with young Yellow-crowned Night-Herons and American Bitterns.

Compared with a Yellow-crowned Night-Heron, the adult Black-crowned has shorter legs, a heavier body, a mostly black crown, and a less dramatic facial pattern. Juveniles generally show larger, bolder spots.

Best identification clues: Stocky shape, black crown and back, gray wings, red eyes, and nighttime activity.

Yellow-Crowned Night-Heron

The Yellow-crowned Night-Heron has a smooth gray body, long yellowish legs, red eyes, and a thick dark bill. Its face has a bold black-and-white pattern topped by a pale yellow or creamy crown.

It usually appears longer-legged and more upright than a Black-crowned Night-Heron. The bill is especially thick because the bird frequently feeds on crabs, crayfish, and other hard-shelled prey.

Yellow-crowned Night-Herons are common around coastal marshes, mangroves, drainage ditches, wooded wetlands, and even wet neighborhood lawns.

Juveniles are brown with small pale spots and fine streaking. Young Black-crowned Night-Herons generally have larger wing spots and heavier streaks.

Best identification clues: Bold black-and-white face, pale crown, thick dark bill, long legs, and preference for crabs.

American Bittern

The American Bittern is a medium-sized marsh heron covered in warm brown, buff, and cream-colored streaks. Its striped plumage helps it disappear among cattails and tall reeds.

When threatened, it may point its bill upward, stretch its neck, and sway gently with the vegetation. This posture can make the bird nearly invisible.

American Bitterns are much larger and heavier than Least Bitterns. They also have thick, strongly streaked necks and broad wings with dark outer feathers.

Juvenile night-herons may appear somewhat similar. However, young night-herons have spotted wings, shorter and thicker bills, and a more hunched shape. American Bitterns are most strongly associated with dense freshwater marshes.

Best identification clues: Large brown body, vertically striped neck, freshwater marsh habitat, and upright camouflage posture.

Least Bittern

The Least Bittern is the smallest heron in North America and is less than half the size of an American Bittern. Its tiny body can be difficult to spot among dense cattails and reeds.

Adults have buff-colored wings, pale underparts, and a dark crown and back. Males usually have darker blackish upperparts, while females tend to be browner. Both have long toes that allow them to grip reeds and climb through marsh vegetation.

Least Bitterns often hold their bodies horizontally between plant stems rather than standing openly in shallow water. Their buff wing panels are especially noticeable when they fly.

Their tiny size separates them from American Bitterns and juvenile night-herons, while their striped neck and pale wing patches distinguish them from Green Herons.

Best identification clues: Extremely small size, buff wing patches, dark back, long toes, and habit of climbing through reeds.

Which White Heron Did You See?

White herons are responsible for plenty of identification confusion. Start with the legs, feet, bill, and body shape.

• Great Egret: Large body, yellow bill, and black legs
• Snowy Egret: Smaller body, black bill, black legs, and yellow feet
• Cattle Egret: Compact body, short yellow bill, and shorter legs
• Juvenile Little Blue Heron: White body with a pale bill and greenish legs
• White Reddish Egret: Shaggy appearance with a pink-and-black bill
• White Great Blue Heron: Very large bird found mainly in southern Florida

Frequently Asked Questions

What is the difference between a heron and an egret?

Herons and egrets belong to the same bird family. The word “egret” is usually applied to species with white plumage or decorative breeding feathers, but it is not a separate scientific group.

Why are bitterns included in a heron guide?

Bitterns are members of the heron family. They generally have shorter legs, thicker necks, and more secretive habits than familiar open-water herons.

What is the largest heron in the United States?

The Great Blue Heron is the largest regularly occurring North American heron. Its long legs and neck make it noticeably taller than other species in this guide.

Which egret has yellow feet?

The Snowy Egret has black legs and bright yellow feet. Cattle Egrets may have yellowish legs, but their feet do not create the same bold contrast.

Are all 12 species found throughout the United States?

No. Their ranges vary by region and season. Coastal states, especially along the Gulf of Mexico and Atlantic Coast, support an impressive variety of herons and egrets.

Naturalist’s Note

Learning to identify herons and egrets changes the way you see a wetland. What once looked like a collection of similar long-legged birds begins to feel more like a community of specialists, each adapted to a slightly different corner of the marsh.

Some species rely on patience. A Great Blue Heron may stand almost motionless before striking, while a Great Egret moves slowly through the shallows. Others use speed and movement. Snowy Egrets stir the water with their feet, Tricolored Herons dart after fish, and Reddish Egrets turn feeding into something that looks almost theatrical.

The smaller species are often the easiest to overlook. Green Herons crouch beneath overhanging branches, and Least Bitterns climb quietly through reeds. American Bitterns may disappear in plain sight, their striped feathers blending with the vegetation so well that even experienced birders can miss them.

Color is helpful, but it is rarely the whole story. Light, distance, age, and breeding plumage can make the same species look surprisingly different. A white juvenile Little Blue Heron may resemble a Snowy Egret, while a white-morph Reddish Egret can create an entirely different identification challenge.

When the plumage leaves you uncertain, watch the bird’s behavior. Notice how it walks, where it feeds, how it holds its neck, and whether it prefers open water, dense reeds, coastal flats, or grassy fields. Those details often reveal more than color alone.

The more time you spend watching these birds, the more distinctive they become. Before long, a quick glimpse of yellow feet, a thick crab-catching bill, or a flash of white belly may be all you need to recognize the species.
