Yellow-legged gull

Larus michahellis

The yellow-legged gull , sometimes referred to as western yellow-legged gull , is a large gull of Europe, the Middle East and North Africa, which has only recently achieved wide recognition as a distinct species. It was formerly treated as a subspecies of either the Caspian gull ''L. cachinnans'', or more broadly as a subspecies of the herring gull ''L. argentatus''.
The genus name is from Latin ''Larus'' which appears to have referred to a gull or other large seabird, and the species name honours the German zoologist Karl Michahelles.

The yellow-legged gull is a large gull, though the size does vary, with the smallest females being scarcely larger than a common gull and the largest males being roughly the size of a great black-backed gull. They range in length from 52 to 68 cm in total length, from 120 to 155 cm in wingspan and from 550 to 1,600 g in weight. Among standard measurements, the wing chord is 40.8 to 47.2 cm , the bill is 4.6 to 6 cm and the tarsus is 5.6 to 7.5 cm . Adults are externally similar to herring gulls but have yellow legs. They have a grey back, slightly darker than herring gulls but lighter than lesser black-backed gulls. They are much whiter-headed in autumn, and have more extensively black wing tips with few white spots, just as lesser black-backed. They have a red spot on the bill as adults, like the entire complex. There is a red ring around the eye like in the lesser black-backed gull but unlike in the herring gull which has a dark yellow ring.

First-year birds have a paler head, rump and underparts than those of the herring gull, more closely resembling first-year great black-backed gulls in plumage. They have a dark bill and eyes, pinkish grey legs, dark flight feathers and a well-defined black band on the tail. They become lighter in the underparts and lose the upperpart pattern subsequently. By their second winter, birds are essentially feathered like adults, save for the patterned feathers remaining on the wing coverts. However, their bill tips are black, their eyes still dark, and the legs are a light yellow flesh colour.

The call is a loud laugh which is deeper and more nasal than the call of the herring gull.

The breeding range is centred on the Mediterranean Sea. In North Africa it is common in Morocco, Algeria and Tunisia and increasing in places. Recent breeding has occurred in Libya and Egypt. In the Middle East, a few breed in Israel and Syria with larger numbers in Cyprus and Turkey. In Europe there are colonies all along the Mediterranean coast, and also on the Atlantic islands and coasts north to Brittany and west to the Azores. It also breeds on the west side of the Black Sea; here it overlaps with the Caspian gull but there is a difference in habitat, with the yellow-legged gull preferring sea cliffs and Caspian gull on flatter shores. In recent decades birds have spread north into central and western Europe. One to four pairs have attempted to breed in southern England since 1995 , though colonisation has been very slow.

Many birds remain in the same area all year round but others migrate to spend the winter in mild areas of western Europe or head south as far as Senegal, the Gambia and the Red Sea. There is also extensive northward post-breeding dispersal in the late summer, with numbers in southern England high from July to October. It is reported as a vagrant to northeastern North America and Nigeria.

Yellow-legged gulls usually breed in colonies. Eggs, usually three, are laid from mid March to early May and are defended vigorously by this large gull. The nest is a sometimes sparse mound of vegetation built on the ground or on cliff ledges. In some places such as Gibraltar they have started nesting on buildings. The eggs are incubated for 27–31 days and the young birds fledge after 35–40 days.
Closeup of a yellow legged gull The yellow-legged gull has only recently been recognised as a species in its own right, having previously been considered to be a race of herring gull. Adults have darker grey backs and wings than herring gulls, but are paler than lesser black-backed gulls. They have more black in the wing tips than herring gulls and smaller white 'mirrors'. The legs are bright yellow, there is a red ring around the eye and the bill is yellow with a large red spot. In non-breeding plumage, the head is less streaked and whiter than herring gulls.

They are omnivores like most ''Larus'' gulls, and they will scavenge on rubbish tips and elsewhere, as well as seeking suitable prey in fields or on the coast, or robbing smaller gulls and other seabirds of their catches.
