The European Herring Gull (Larus argentatus) is a large, familiar gull found along coastlines, lakes, rivers, farmland, and increasingly in European towns and cities. Adults are easily recognized by their pale-gray backs, white heads and underparts, pink legs, heavy yellow bills, and black wingtips.
Although commonly called a “seagull,” it is not restricted to the sea. European Herring Gulls are adaptable birds that feed on marine animals, insects, eggs, carrion, and discarded human food.
European Herring Gull Identification
European Herring Gulls are large, strongly built birds with broad wings, a thick neck, a heavy bill, and relatively long legs. They often look bulky when standing but appear powerful and graceful in flight.
Adult Appearance
A breeding adult can be identified by:
- White head, neck, tail, and underparts
- Pale silver-gray back and upper wings
- Black outer wingtips with white spots
- Pink legs and webbed feet
- Heavy yellow bill
- Red spot near the tip of the lower bill
- Pale yellow or silvery-looking eyes
- Red or orange eye ring
The combination of a pale-gray back, pink legs, and a red-marked yellow bill separates adults from many similar gulls. Their body length is generally about 54–60 centimeters.
During winter, adults may develop gray or brown streaking over the head and neck. This gives them a less clean-headed appearance than their bright breeding plumage.
Size and Weight
European Herring Gulls are among the larger commonly encountered European gulls.
| Measurement | Approximate range |
| Body length | 54–60 cm |
| Average adult weight | Around 970 g |
| Recorded adult weight range | About 757–1,264 g |
| Average wing length | About 41 cm |
| Typical lifespan after reaching breeding age | Around 12 years |
Males and females have similar plumage, but males are generally larger and may have heavier bills. Size is easiest to judge when a pair is standing together.
Juvenile European Herring Gull
Young Herring Gulls look very different from adults. A first-year bird is predominantly mottled brown, with dark markings across its head, breast, back, wings, and underparts.
Juvenile Identification
A young bird commonly has:
- Brown and cream mottled plumage
- Dark bill
- Pinkish legs
- Dark eyes
- Heavily patterned wings
- Dark tail band
- Pale inner wing areas visible during flight
Juveniles become progressively paler and more adult-like through successive molts. Because Herring Gulls normally do not begin breeding until about four years old, several intermediate plumages may be seen between the dark juvenile and clean gray-and-white adult stages.
Immature gull identification can be difficult because young Lesser Black-backed, Great Black-backed, Yellow-legged, and other large gulls may all appear brown and heavily marked.
European Herring Gull in Flight
In flight, the European Herring Gull shows broad, relatively long wings and a steady, powerful wingbeat. It may also soar or glide for long periods, especially in strong coastal winds.
An adult flying overhead shows:
- White body and tail
- Pale-gray upper wings
- Black outer wingtips
- White spots within the black tips
- Pale underwings
- Broad, slightly rounded wing shape
Herring Gulls are capable of hovering briefly into the wind, following fishing boats, and maneuvering around buildings. They often travel between coastal feeding areas, fields, refuse sites, reservoirs, and urban nesting areas.
Habitat and Range
European Herring Gulls breed across northern and western Europe. Two recognized subspecies occur: Larus argentatus argenteus in the western part of the range and Larus argentatus argentatus farther east.
Natural Habitat
Typical habitats include:
- Rocky coastlines
- Offshore islands
- Sea cliffs
- Beaches and estuaries
- Intertidal mudflats
- Freshwater lakes
- Rivers and reservoirs
- Marshes and farmland
- Moorland
- Coastal grassland
Northern populations are more likely to migrate, whereas many birds in Britain, Ireland, and other relatively mild regions are resident, nomadic, or only locally migratory.
Urban Habitat
Herring Gulls increasingly nest and feed in towns and cities. Flat rooftops, chimneys, ledges, and industrial buildings can resemble the open, elevated nesting locations used along cliffs.
Urban areas may also provide easy access to food waste and fewer ground predators. Herring Gulls began using British rooftops regularly during the twentieth century and often return to the same nesting area year after year.
What Do European Herring Gulls Eat?
European Herring Gulls are opportunistic omnivores. Their natural diet includes a wide variety of marine and terrestrial foods.
Natural Foods
They commonly eat:
- Fish
- Mussels and other mollusks
- Crabs and crustaceans
- Marine worms
- Insects
- Earthworms
- Small mammals
- Birds and chicks
- Bird eggs
- Carrion
- Seeds and plant material
Coastal birds frequently search beaches, rocky shores, mussel beds, and intertidal areas. GPS research on breeding Herring Gulls at one declining British colony found that many feeding trips were concentrated around intertidal and nearshore habitats, particularly mussel beds.
Human Food and Waste
Herring Gulls also feed at refuse sites and take discarded food in towns. They may steal unattended food, tear open waste bags, or gather around fishing boats.
However, their urban behavior does not mean they naturally prefer bread, chips, or processed food. Marine prey remains important, even for many birds nesting in built-up locations. Feeding gulls can encourage crowding and conflict and may provide a nutritionally poor diet.
Feeding Behavior
A Herring Gull may stamp its feet rapidly on grass, imitating rainfall and encouraging earthworms to move toward the surface. It also drops mussels and other hard-shelled prey onto rocks or pavement to break them open.
These gulls forage by walking, swimming, surface-dipping, scavenging, stealing prey from other birds, and taking food directly from the ground or water.
Call and Communication
European Herring Gulls are vocal birds with several loud calls. The classic call is a long, laughing series frequently heard around seaside towns and nesting colonies.
Other sounds include:
- Short warning notes
- Harsh alarm calls
- Begging calls from chicks
- Territorial calls between adults
- Repeated calls during courtship
Adults may throw their heads upward while delivering the long call. Around nests, they become especially noisy when people, dogs, foxes, or other gulls approach.
Nesting and Reproduction
European Herring Gulls nest alone or in colonies. Natural nesting sites include cliff ledges, islands, beaches, moorland, marshes, and areas beside freshwater. Urban birds use rooftops, chimneys, gutters, and other flat structures.
Nest and Eggs
The nest is usually a shallow structure made from:
- Grass
- Seaweed
- Twigs
- Moss
- Feathers
- Other available vegetation
A typical clutch contains three eggs, although two to four may occur. The eggs are commonly olive, greenish, or brownish with darker spots, which help camouflage them against the nest material. Incubation usually lasts 28–30 days.
Chicks and Fledglings
Newly hatched chicks are downy and can move around shortly after hatching. They peck at the red spot on the adult’s bill, stimulating the parent to regurgitate food.
Young gulls normally take approximately 35–40 days to fledge. Parents remain strongly protective and may call, dive, or swoop at perceived threats near the nest.
European vs. American Herring Gull
Modern eBird/Clements taxonomy recognizes the European Herring Gull as Larus argentatus and the American Herring Gull as Larus smithsonianus. Older references sometimes treated them within a broader Herring Gull group.
Adults are extremely similar. Both have pale-gray backs, pink legs, yellow bills with red markings, and black wingtips. Differences involving wing-tip patterns, winter head streaking, body structure, and immature plumage are often subtle and require careful observation.
Geographic location is usually the strongest initial clue: European Herring Gulls occur primarily in Europe, whereas American Herring Gulls are native to North America.
European Herring Gull vs. Similar Gulls
Ring-Billed Gull
A Ring-billed Gull is smaller and more delicately built. Adults have yellow legs and a distinct black ring around the yellow bill. European Herring Gulls have pink legs, a heavier bill, and a red spot rather than a complete black ring.
Lesser Black-Backed Gull
The Lesser Black-backed Gull has a much darker slate-gray back and yellow legs. The European Herring Gull has a pale-gray back and pink legs.
Common Gull
The Common Gull resembles a smaller, neater Herring Gull. It has a slimmer bill, greenish-yellow legs, and a more delicate body. The Herring Gull is considerably larger, with pink legs and a red spot on its heavier bill.
Conservation Status
The European Herring Gull remains widespread and is globally categorized as Least Concern, but important regional populations have declined. In the United Kingdom it is Red-listed because of long-term reductions in breeding and wintering numbers. Monitoring data also show substantial declines among naturally nesting British populations since 2000.
Possible pressures include reduced natural food availability, changes in fishing and landfill practices, disease, predation at colonies, disturbance, bycatch, and habitat changes. Their visibility in towns can create the misleading impression that the overall population is increasing everywhere.
FAQs
Is a Herring Gull the Same as a Seagull?
“Seagull” is an informal name used for many gull species. The European Herring Gull is one specific species, and it may live far inland as well as beside the sea.
How Long Do European Herring Gulls Live?
A bird that survives to breeding age has a typical life expectancy of around 12 years. Some individuals may live considerably longer, but many young birds die before reaching maturity.
Do Herring Gulls Mate for Life?
Pairs may maintain long-term bonds and often return to the same nesting area. However, partnerships can change when a mate dies or fails to return.
Are European Herring Gulls Aggressive?
They are not normally aggressive without a reason, but nesting adults strongly defend their eggs and chicks. Swooping usually occurs when they believe a person or animal is approaching the nest.
Are Herring Gulls Protected?
Wild gulls and their active nests are protected under wildlife laws in many European countries. Rules vary by location, so nests, eggs, or chicks should not be removed without checking the applicable law and licensing requirements.
