Gaviota de marfil (Pagophila eburnea)
Amazing views of the first winter Ivory Gull at Gujan-Mestras, Aquitanie, France.
It was easily observed by several french, belgian and spanish birders while it was feeding on oysters at the harbour. A real MEGA!
Also at the same place: 3 Glaucous Gulls (2 of them oiled), several Ring billed... and up to 11 different gull species. A must for all gull lovers.
