Putative intermedius

Among the many lesser black-backed gull (Larus fuscus graellsii) feeding on the edge of a falling tide along the Riverfront, Newport last weekend, was an individual that clearly sported a darker mantle. Although care needs to be taken when separating lesser black-backed gull subspecies it does suggest this bird is of the subspecies f.intermedius a species known to breed in Belgium and the Netherlands.
