29-7-2025 ALESUND AQUARIUM, NORWAY - EUROPEAN HERRING GULL (Larus marinus)

The European herring gull (Larus argentatus) is a large and robust seabird, with a length of up to 66 cm (26 inches). It is a familiar sight along the coastal regions of Western Europe and is known for its striking appearance and adaptability to various environments.

Adult European herring gulls have a light grey back and upper wings, with a white head and underparts. Their wingtips are marked with black and white spots known as "mirrors." The bill is a bright yellow with a red spot near the tip, and the legs are typically pink, although they can sometimes be yellowish. Juveniles are mottled brown with darker streaks and possess a dark bill and eyes. As they mature, their plumage gradually lightens, reaching full adult coloration and sexual maturity at around four years of age.

These gulls are commonly found in coastal areas, but they have also adapted to urban environments where they can be seen nesting on rooftops and scavenging for food.

24-7-2025 COBH, IRELAND - EUROPEAN HERRING GULL (Larus marinus)

 The European herring gull (Larus argentatus) is a large gull, up to 66 cm (26 in) long. It breeds throughout the northern and western coasts of Europe. Some European herring gulls, especially those resident in colder areas, migrate further south in winter, but many are permanent residents, such as in Ireland, Britain, Iceland, or on the North Sea shores. They have a varied diet, including fish, crustaceans, as well as some plants, and are also scavengers, consuming carrion and food left by or stolen from humans.

The male European herring gull is 60–67 cm (24–26 in) long and weighs 1,050–1,525 g (2.315–3.362 lb), while the female is 55–62 cm (22–24 in) and weighs 710–1,100 g (1.57–2.43 lb). The wingspan can range from 125 to 155 cm (49 to 61 in).  Among standard measurements, the wing chord is 38 to 48 cm (15 to 19 in), the bill is 4.4 to 6.5 cm (1.7 to 2.6 in) and the tarsus is 5.3 to 7.5 cm (2.1 to 3.0 in).[8] Adults in breeding plumage have a light grey back and upper wings and white head and underparts. The wingtips are black with white spots known as "mirrors". The bill is yellow with a red spot and a ring of bare yellow skin is seen around the pale eye. The legs are normally pink at all ages, but can be yellowish, particularly in the Baltic population, which was formerly regarded as a separate subspecies "L. a. omissus". Non-breeding adults have brown streaks on their heads and necks. Male and female plumage are identical at all stages of development, but adult males are often larger.

Juvenile and first-winter birds are mainly brown with darker streaks and have a dark bill and eyes. Second-winter birds have a whiter head and underparts with less streaking and the back is grey. Third-winter individuals are similar to adults, but retain some of the features of immature birds such as brown feathers in the wings and dark markings on the bill. The European herring gull attains adult plumage and reaches sexual maturity at an average age of four years.

They have been recorded from all the coasts of Europe including the Mediterranean and occasionally inland. Vagrants have been recorded in Israel, Cyprus and Turkey.

Birds in France are mainly resident, but northern populations migrate in winter, generally to the coasts of north-western Europe.

6-10-2024 TARBERT ISLAND, IRELAND - EUROPEAN HERRING GULL (Larus marinus)

The European herring gull (Larus argentatus) is one of the best-known of all gulls along the shores of Western Europe, it was once abundant. While the numbers of these birds appear to have been harmed in recent years, possibly by fish population declines and competition, they have proved able to survive in human-adapted areas and can often be seen in towns acting as scavengers.

6-7-2024 ROTTERDAM ZOO, NETHERLANDS - EUROPEAN HERRING GULL (Larus marinus)

Herring Gulls are large, noisy gulls found throughout the year around our coasts and inland around rubbish tips, fields, large reservoirs and lakes, especially during winter. Adults have light grey backs, white under parts, and black wing tips with white 'mirrors'. Their legs are pink with webbed feet and they have heavy, slightly curved bills marked with a red spot. Young birds are mottled brown. This species is on the Red List due to ongoing population declines and wintering population declines.

A large gull, which in adult plumage has light grey upperwings, showing black tips with white 'mirrors' (white at the very tips surrounded by black); the rest of the plumage is white. Similar to Common Gull in colouration, but separated by size, Common Gull is much smaller and shows larger, more conspicuous white 'mirrors' at the wing tip as an adult. Adult birds have heavy yellow bills with a orange spot on the lower bill, the head is pure white in the summer and streaked in the winter. The legs are pink at all ages. Herring Gulls have four age groups and attain adult plumage after three years when they moult into adult winter plumage. Juveniles are brown with finely patterned feathers which fade in the first year, especially the wing and tail feathers which are retained through the first summer.

Juvenile and first year birds, do not have any plain grey adult like feathers in the upperparts and can be difficult to tell apart from immature Lesser and Great Black-back Gulls. Grey in the upperparts develops from the second winter onwards, initially mostly in the mantle and back and becomes more extensive over the wings as the bird moves towards maturity. Younger immature birds have a dark terminal tail band which becomes less prominent as they get older, adult birds lack this band completely.

Calls are strident and loud.

Both predator and scavenger, often feeds on the coast and follows fishing boats and uses landfill sites.

Breeds in colonies around the coast of Ireland and also inland in Co. Donegal and Co. Galway. The biggest colony in Ireland is on Lambay island off Co. Dublin with over 1,800 nests.

Widespread on the coast and inland.

They have a varied diet, including fish, crustaceans, as well as some plants, and are also scavengers, consuming carrion and food left by or stolen from humans.

European herring gull flocks have a loose pecking order, based on size, aggressiveness, and physical strength. Adult males are usually dominant over females and juveniles in feeding and boundary disputes, while adult females are typically dominant when selecting their nesting sites.

The European herring gull has long been believed to have extremely keen vision in daylight and night vision equal or superior to that of humans; however, this species is also capable of seeing ultraviolet light. This gull also appears to have excellent hearing and a sense of taste that is particularly responsive to salt and acidity.

Parasites of European herring gulls include the fluke Microphallus piriformes.

European herring gulls breed across Northern Europe, Western Europe, Central Europe, Eastern Europe, Scandinavia, and the Baltic states. Some European herring gulls, especially those residents in colder areas, migrate further south in winter, but many are permanent residents, e.g. in Ireland, Britain, Iceland, or on the North Sea shores. These birds inhabit coastal areas, lakeshores, reservoirs, intertidal pools, mudflats, and newly plowed fields. They can also be found in human-adapted areas and can often be seen in towns.
