Black-headed Gull, Larus ridibundus (A179)

Annexe II partie B

The Black-headed gull is an elegant water bird: both sexes are identical in appearance. During the breeding season, the back and tops of the wings are light grey. The external primaries are white, with black tips. The leading edge of the wing is pure white, becoming black towards the outside primaries. The primaries are dark underneath. The Black-headed gull has in fact a dark brown head that extends to just behind the ears and a white half circle around the back of the eye. The under parts are white, sometimes with a rose tint on the breast during the spring. The tail is white. The bill, legs and toes are a very dark red. The eyes are dark. In wintertime, adults have dark patches behind the eyes; the brown head disappears after the breeding season. Two indistinct black bars can be seen across the head. The bill is red with a black tip. Legs and feet are red. Juveniles and young do not have a dark head.

Food
Omnivorous. The Black-headed gull feeds mainly on aquatic and terrestrial insects, sea invertebrates, fish and worms. It also eats fruit, seeds, general waste and sometimes mice. It feeds and sleeps in large groups. An opportunistic feeder, it can be seen cleaning up in town centres and on beaches, as well as feeding in a ploughed field where groups follow the tractor and fill up on worms and other insects. This bird can feed itself while walking, swimming or even by diving to catch fish, often behind fishing boats. It can fly across the waves and catch insects at the water’s surface.

Nesting
The Black-headed gull prefers vegetated sites, on which it builds a nest out of vegetation. It often breeds in mixed colonies.

Conservation status
On a European scale, the population has seen a sharp increase and its conservation status is considered favourable. Within the Life+ ENVOLL project, a small increase has been observed in less than 10 years.

Population size
* In France : at least 27 000 - 31 000 breeding pairs in 2009-2011
* Across the zone covered by the Life+ ENVOLL project :
— > in 2014 : 2928 breeding pairs
— > in 2015 : 3107 breeding pairs
— > in 2016 : 3502 breeding pairs
