3cy, look-alike, Iceland
Posted: Sun Dec 30, 2018 6:41 pm
This 3cy herring gull was photographed by Alex Máni in SW-Iceland on the 17th of November 2017. It appears to be highly retarded, e.g. when compared to the other 3rd cy flying besides it. Note the heavily barred underparts and lots of black in secondaries and the tail and still some dense barring on the rump.
