Litz, it is interesting how different swans react on people. The above photo was taken in a rural country, so not many people passing. Some time ago I photographed a swan family ( http://www.fotothing.com/senna3/photo/e590adfb5a44ba4bf590d9ec53b6c87a/ ) and they were almost posing for me, presumably expecting food. This was in an urban neighbourhood with many people around!
