Juv Caspian Gull at Germignaga, Varese, NW Italy on Jul 29 to Aug 2, 2006

A juv Caspian Gull (Larus cachinnans) was observed and photographed by Michele Viganò at Germignaga, Varese, NW Italy on Jul 29 to Aug 2, 2006. The bird's central tail feathers was showing a very weak and abraded tail-bar and an obvious black-extra bar. Moreover, some second generation outermost tail feathers were still growing due to the accidental moult of part of the tail (the Americans tend to call this 'adventitious molt') and were showing a fuller tail-bar, lacking apparently any extra-bars.
