It has travelled up the Durance and settled on the lake, where it finds propitious conditions for its survival (open water). This gull, a cousin of the seagulls, is omnivorous. The colony can be seen around the lake all year round. They are generally grey or white, with black markings on the wings. They have a long, thick beak and yellow webbed feet. The young are grey in colour and take two to four years to acquire adult plumage.
