[QUOTE="lou salomon, post: 1412982, member: 16268"] [b]heads of adult alternate caspian[/b] most pics available on the net show adult caspians in wintertime, when they visit western europe and most show a dark subterminal band on bill. this is a short series of heads of male caspians from the danube delta in spring time (alternate plumage, febr-june). no dark winter subterminal band, most males with paler iris and a huge bill, often also with a 'hanging' gonys angle. no. 3 is a subadult (4cy may). all are crops of pics by daniel petrescu, whole birds visible soon on a website on romanian gulls.
