9 Types of Herons in New Jersey: How to Identify Every Species
September 25, 2026
New Jersey’s wetlands host a surprising variety of long-legged waders, and most of the types of herons in New Jersey spend at least part of the year fishing the state’s marshes, bays, and retention ponds. Nine species show up with enough regularity that a patient observer at Forsythe National Wildlife Refuge or the Hackensack Meadowlands can realistically spot several in a single outing. That count includes both the “true” herons and their all-white relatives, the egrets, since both groups belong to the same family and share the same stalking, spear-fishing lifestyle.
This guide breaks down each species by size, color, behavior, and where in the state to look for it. For a broader look at how these birds compare to other wading species, the different types of water birds found across the country share many of the same hunting strategies.
Pro Tip: Early morning and dusk are the most productive times to find herons and egrets, since several species feed most actively during low light and are easier to approach before foot traffic picks up at popular refuges.
1. Great Blue Heron
The Great Blue Heron (Ardea herodias) is the largest and most familiar heron in the state, standing roughly four feet tall with a gray-blue body and a black stripe running above the eye. It hunts alone but nests in colonies, and Bird Advisors notes that the nests are found in colonies, high up in trees close to water, and are made with twigs and sticks lined with softer material. Because the birds reuse and repair the same structures year after year, a single rookery can hold dozens of active nests.
Great Blue Herons are also the most consistently reported heron on New Jersey checklists. They are recorded in 20% of summer checklists and 14% of winter checklists submitted by bird watchers for the state, which reflects how many stay through the colder months rather than migrating south. Despite that abundance, the species carries a conservation flag: research on the species shows the population has been steadily dropping, leading to the classification of Species of Special Concern in New Jersey, largely tied to wetland loss. Birders looking to compare notes across state lines can check how the species behaves in the herons of New York, where similar habitat pressures apply.
2. Green Heron
Much smaller and stockier than its blue-gray cousin, the Green Heron (Butorides virescens) has a slaty blue-green back, a chestnut neck, and yellow legs. It is one of the few North American birds known to use tools, and according to Birdshow.blog, it is known to use tools like bread or feathers as fishing lures, dropping bait onto the water to draw fish within striking range.
Green Herons favor freshwater and saltwater marshes, streambanks, and pond edges, where their dark plumage blends into overhanging brush. Seasonal timing matters here: most arrive in late spring and clear out again in fall, since Green Herons arrive in late April and depart by October. Anyone comparing populations further south may notice similar arrival windows in the herons found in Virginia.
3. Black-crowned Night-Heron
The Black-crowned Night-Heron (Nycticorax nycticorax) is a stocky, hunched bird with a black cap and back, gray wings, and striking red eyes. The NYC Bird Alliance describes it as a striking gray, black, and white bird recognizable by its “hunched old man” posture, a nickname that fits once you see one roosting motionless in a tree.
True to its name, this species does most of its hunting after dark. It roosts by day in dense cover and becomes active at dusk, a strategy that helps it avoid competing with the day-active herons and egrets sharing the same marshes. It also happens to be remarkably widespread: Black-crowned Night-Herons are the most widespread heron in the world, even though they can be hard to actually locate.
New Jersey’s largest colonies form at sites like the Hackensack Meadowlands, and the species’ glossy black crown gives it a passing resemblance to some of the types of black birds found elsewhere in the state, though the two groups are not related.
4. Yellow-crowned Night-Heron
The Yellow-crowned Night-Heron (Nyctanassa violacea) is the rarer of New Jersey’s two night-heron species. It shares the stocky, short-necked build of its black-crowned relative but has a bulkier head, pale gray body, and a bold black-and-white facial pattern. Crustaceans, especially crabs and crayfish, make up a large share of its diet, which is one reason it favors tidal creeks and wooded swamps over open marsh.
Sightings in New Jersey are concentrated in the southern part of the state. According to a New Jersey heron field guide, Yellow-crowned Night-Herons are scarcer, nesting mainly in southern wooded swamps, which makes locations like Heislerville and the Delaware Bay marshes worth checking during the breeding season. Birders scouting for the species out west may want to compare it against the herons recorded in California, where a similar coastal-swamp preference shows up.
5. Great Egret
The Great Egret (Ardea alba) is arguably the most photogenic heron in the state, with pure white plumage and, during breeding season, long feathery plumes called aigrettes that are raised during courtship displays. Those same plumes nearly caused the bird’s downfall a century ago.
Per Bird Watching HQ, Great Egrets were almost hunted to extinction in the 19th century because these feathers made such nice decorations on ladies’ hats, and the backlash to that trade led directly to organized bird conservation in America. Fittingly, the Great Egret serves as the symbol for the National Audubon Society today.
Slightly smaller than a Great Blue Heron, this species is an opportunistic feeder that eats reptiles, amphibians, small mammals, and countless invertebrates. Its call is a rough croak rather than anything musical, and it’s often the easiest heron for beginners to identify simply because there’s no all-white bird its size to confuse it with. Comparisons with the population documented in the herons of Oregon show a similar recovery story tied to plume-hunting bans.
6. Snowy Egret
The Snowy Egret (Egretta thula) is smaller and more delicate than the Great Egret, with black legs, yellow feet, and a slender black bill. Unlike the darker herons that rely on camouflage, this bird stands out wherever it goes. As New Jersey Kayaking puts it, the Snowy Egret makes no attempt at camouflage, and stands out in any environment, which is part of what makes it a favorite subject for paddlers and photographers alike.
Snowy Egrets hunt with more flair than most herons, sometimes hovering or “dip-fishing” with their feet skimming the water’s surface. They will also forage in mixed-species groups, following disturbances kicked up by other wading birds. The species is common enough along the coast that it would be difficult to go out kayaking and not spot at least one. Readers curious how this compares regionally can check the heron species found in Tennessee, where Snowy Egrets show a similar seasonal pattern.
7. Cattle Egret
The Cattle Egret (Bubulcus ibis) breaks the mold for herons in almost every way. Rather than wading through water, it spends most of its time in open fields, following livestock and snapping up insects stirred loose by grazing animals. It’s not native to North America at all: Bird Watching HQ reports that Cattle Egrets are originally from Africa but found their way here in the 1950s and have since spread across the country.
The species’ range has kept expanding as more land gets converted to farming and pasture, and its raspy “rick-rack” call is one of the easier heron sounds to learn since it’s given year-round rather than only during breeding season. In New Jersey, Cattle Egrets show up most reliably in agricultural areas of the south and central counties. A similar pattern of range expansion appears in the population covered by the guide to herons in Minnesota, a state well outside the species’ original range.
8. Little Blue Heron
The Little Blue Heron (Egretta caerulea) is a slate-blue bird with a two-toned bill, and its juveniles are entirely white, which regularly causes confusion with Snowy Egrets in the field. Adults develop darker plumage and a maroon-tinged head and neck during the breeding season, while young birds gradually molt from white to blue over their first year.
Conserve Wildlife Foundation of New Jersey lists the species as one facing real pressure in the state: this species is listed as Special Concern during the breeding and non-breeding seasons, and nesting locations within New Jersey have only been documented along the shorelines of Barnegat Bay and south. Habitat loss along that coastline is the main driver behind the listing, since the birds depend on undisturbed trees and shrubs near salt or brackish water for nesting.
Important Note: Conservation status for the Little Blue Heron varies slightly by source and survey year. New Jersey’s state wildlife program lists it as a Species of Special Concern, while some regional summaries describe it as Threatened, reflecting differences in how states classify declining wetland species. Either way, the population trend in New Jersey is downward, so treat any nesting colony as sensitive habitat.
9. Tricolored Heron
The Tricolored Heron (Egretta tricolor) is the most striking of New Jersey’s coastal herons, with blue-gray and lavender upperparts, a white belly, and a distinctive white stripe running down the front of its neck. According to Avian Report, it’s an uncommon summer resident and transient in New Jersey, present from late spring through early fall, which makes it more of a specialty sighting than something you’ll stumble across on every trip to the shore.
Tricolored Herons hunt with noticeably more energy than most of their relatives, often stalking, or chasing prey with sudden stops and wing flaps rather than standing perfectly still. They will also trail behind cormorants and grebes, snatching up fish the larger birds stir loose. Interestingly, Snowy Egrets are known to interbreed with several of New Jersey’s other small herons, and Bird Watching HQ notes that Snowy Egrets will breed with other heron species, such as other similarly sized birds like Tricolored Herons, Little Blue Herons, and Cattle Egrets, so an odd-looking bird at a mixed colony may well be a hybrid rather than a misidentification.

Wetland loss remains the common thread tying together the conservation stories of nearly every species on this list. As one regional wildlife group puts it, wetland destruction due to urbanization and development is one of the primary drivers to shrinking heron populations in the state. Protecting the marshes, bays, and swamp edges these birds depend on is ultimately what keeps New Jersey’s heron and egret population viewable for the next generation of birders, and further afield the same pressures shape heron populations documented in places like Maryland.
