Caspian Gull (cachinnans) 2cy, February 19 2012, Zagreb, Croatia.

Two pictures of this bird, to illustrate a common moult extent in first winter cachinnans. Images show the 2nd generation wing-coverts in 2cy cachinnans in spring. These 2nd gen feathers were attained already in September-November, and now, by February, the tips of the 2nd gen feathers are already slightly worn. Of course, the outer wing-coverts which are still juvenile, are even more abraded and most old juvenile feathers have hardly any white fringe left.
