Larus cachinnans 1cy, October 25 2009, Westkapelle, the Netherlands. Picture: Ies Meulmeester.
In every respect a very typical and beautiful 1cy Caspian Gull. This bird has replaced nearly all scapulars to second generation feathers, all other coverts are still juvenile. The coverts are white-edged and show hardly any barring. The median and especially the greater coverts have white tips. The under-wing coverts become very white coloured. The inner five primaries of the long wing have a pale inner and a dark outer web, in a spread wing creating a "Venetian blind", Also note the pale "apical spots" on the outer webs of P2-3.
