Physical description Click here for a physical description Lesser Black-backed Gulls are large white-headed gulls. They take three years to reach maturity, so there are four different phases of plumage. During the breeding season, adult Lesser Black-backed Gulls have an all-white head and front, with narrow red eye-rings. Depending on race, the mantle and upperwings can be slate-grey to jet-black. The wings have a narrow white trailing edge and also leading edge outside the alula, and four white spots on the ends of the outer flight feathers that are prominently visible on the folded wings. In eclipse the head and hindneck become streaked grey. Their most prominent (but not unique!) feature is the strong, yellow bill with a red spot near the tip of the lower mandible. The irises are pale-grey. The legs and feet are greyish-yellow. There are 3 different immature plumages. The plumage of two year old birds already closely resembles that of adults, but with some residual grey streaking on the head and neck and with some sub-adult wing coverts. The bill is mostly olive-grey, with a black band across both mandibles near the tip. The legs and feet are greyish-pink. One year old birds have a mottled grey head, a mostly light-grey front and mottled grey sides. The wings are mostly grey, with some mottling on the coverts; the tips of the outer primaries and the tail are black. The legs and feet are still greyish. The irises are quite dark. The frontal half of the bill is black, with a light-grey tip, the base is grey. Juveniles have an all-black bill, a strongly streaked front and boldly scalloped brownish-grey mantle and wings with pale tail tips.

Range, habitat, finding this species Click here for information on habitat and range The overall distribution of this species can be assessed, and specific locations where birds have been spotted can be found, based on individual sighting reports submitted by birdwatchers to ebird.org . The global distribution of the Lesser Black-backed Gull is available HERE . There are 5 extant races of the Lesser Black-backed Gull, which are a partly sedentary, partly migratory species. Their overall range extends from parts of North America (in particular the eastern half of the continent) via New Foundland, Greenland, Iceland and Svalbard to Europe, north-western and northern coastal Africa, the river Nile valley, Asia Minor, parts of the Middle East and near-coastal Arabia into Asia, including the Indian subcontinent. In the East their range extends to eastern China, the Korean peninsula and parts of Japan. In Europe Lesser Black-backed Gulls are partly sedentary and partly migratory species that is found only in (near-)coastal areas. Their winter grounds range from the Irish, English and Benelux coastlines southward along the French and Iberian coastline into the entire Mediterranean. In the northern part of that wintering range, from central Iberia northward, there are also areas where Lesser Black-backed Gulls stay all year round. They are summer breeding migrants in the northern parts of their range, which encompasses Scotland and associated islands (up to Iceland) and the German, Danish and Scandinavian Atlantic coastline, as well as the northern Baltic Sea coastline and the Finnish lake district. During their migration the Baltic breeding population may be found along distinct flight paths towards the Adriatic, the Bosporus and the western half of the Black Sea.

Sightings Click here for sighting information Race "intermedius" M. Thomas reports spotting Lesser Black-backed Gulls, race "intermedius", in Lökken, Jütland, Denmark, in September 2019. J. Pires found a Lesser Black-backed Gull, race "intermedius", on Morraceira island, Figueira da Foz, Mondego estuary, Portugal, in January 2023. Race "graellsii" Both G. Pinelas and J. Pires report spotting Lesser Black-backed Gulls, race "graellsii", regularly on the coastline of southern/central Portugal. C. Pears found Lesser Black-backed Gulls, race "graellsii", at Crail, near St Andrews, Scotland, in September 2017.
