Laughing gulls are common along the shores of the Atlantic. They can be found in Europe as well. The laughing gull's English name is derived from its raucous kee-agh call, which sounds like a high-pitched laugh "ha... ha... ha...". They have dark grey wings. Adults may have black head and a black hood. Black hoods, however, can be lost in winter. They have black feet and beaks, but beaks can be red. It's a mid-size bird. (source wikipedia)
