Description
The Common Gull is larger than the Black-headed Gull, but smaller than the Herring Gull.
As with most gulls, the plumage of the Common Gull varies greatly and depends on age and the time of year. In the summer, the adult birds have grey wings, back and mantle, and white head, neck and breast. The wings have black tips with white spots. The legs and bill are yellow-green.
In the winter, the bill is duller with a thick black band towards the tip, and the head is streaked grey.
The plumages of juveniles and immature birds are complex, but basically mottled brown.
Voice
Their calls are high pitched, some are laughing calls, others are mewing calls: "keow".
Feeding
As well as scavenging, Common Gulls feed on worms, insects, molluscs and fish.
Breeding
The nest is made from seaweed and other plant material. Both birds build the nest, which is usually on the ground and in a colony.
The greenish eggs have brown blotches on them and are smooth and non-glossy. They are about 58 mm by 41 mm in size. Both birds share the duty of incubating the eggs and feeding the precocial nestlings.
