Physical description Click here for a physical description Audouin's Gulls are medium-sized, white-headed gulls and the smallest of the "large white-headed gulls". They take four years to reach maturity, so there are five different phases of plumage. During the breeding season, adult Audouin's Gulls have a white head and front, sometimes tinged with very light-grey, and a light-grey back and wing coverts. The primaries have black tips with 'string of pearl' white points at the ends, rather than big white panels. The trailing edge of the upperwings has almost no white, leading to a near-absent tertial crescent on the folded wings. The irises are brown, while the bill is dark-red with black markings near the tips of both mandibles; the legs and feet are greenish-grey. Compared to other great white gulls, Audouin's Gulls look slender. There are 3 different immature plumages. The plumage of third-year birds already closely resembles that of adults, but with some residual grey streaking on the head, nape of the neck and some of the flight feathers. The bill is mostly dark-red, with a black tip across both mandibles. Second-year 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 irises are quite dark and the legs and feet are dark-grey. The frontal half of the bill is black, the base is grey. Except for a grey front of the head and a grey belly, first-year Audouin's Gulls are mottled grey all over, with bold dark centres on the wing coverts. The irises are dark. The bill is grey with a black tip. Juveniles have an all-black bill, a light-grey head with clearly visible white eye-rings, a smooth, unstreaked mid-grey front and boldly scalloped brownish-grey wings.

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 Audouin's Gull is available HERE . Audouin's Gulls have a restricted range, in which they are partly migratory. Their breeding grounds are located on rocky islands or shores around the Mediterranean Sea. Around the Mediterranean there are locations where some Audouin's Gulls are resident, while others either disperse or migrate to western coastal Africa, as far southward as Senegal. In Europe Audouin's Gulls are found in Iberia, along the Mediterranean coastline and, especially, on all Mediterranean islands with suitable rocky habitats for breeding. Being specialised on feeding on fish, Audouin's Gull is also almost exclusively coastal/pelagic outside the breeding season. Beyond the Mediterrean, there are some records of Audouin's Gulls traveling northwards along the European Atlantic coastline. Audouin's Gulls are a strictly coastal or pelagic species. They breed on rocky islands and rocky shores.

Sightings Click here for sighting information G. Pinelas reports spotting Audouin's Gulls occasionally along the coastline of southern/central Portugal, around the Tejo estuary. J. Pires also reports finding Audouin's Gulls in various coastal locations in southern/central Portugal, down to Sagres, on the south-western tip of Iberia.
