The Black-headed Gull (Chroicocephalus ridibundus) is a small gull which breeds in much of Europe and Asia, and also in coastal eastern Canada. Most of the population is migratory, wintering further south, but some birds in the milder westernmost areas of Europe are resi-dent. Some birds will also spend the winter in northeastern North America, where it was for-merly known as the Common Black-headed Gull.
This gull is 38–44 cm (15-17½ in) long with a 94–105 cm (37–41 in) wingspan. In flight, the white leading edge to the wing is a good field mark. The summer adult has a chocolate-brown head (not black, despite the name), pale grey body, black tips to the primary wing feathers, and red bill and legs. The hood is lost in winter, leaving just dark vertical streaks. It breeds in colonies in large reedbeds or marshes, or on islands in lakes, nesting on the ground.
Like most gulls, Black-headed Gulls are long-lived birds, with a maximum age of 63 years recorded in the wild.
