1 w. Lesser black-backed gull (L. fuscus), 14-02-10




1 w. Lesser black-backed gull (L. fuscus), 14-02-10. Note the very patterned Greater and Median Coverts which ressembles Herring Gull. However some of the second generation scapulars are dark and in the field the general structure was more obvious than in the pics. In flight the identification is obvious because of the lack of primary window
