Gulls in 1.Year: could the lefthand bird be a L.michahellis? The right bird I think is L.cachinans. 05.08.2016 in Constanza.

Therefore we have an interesting situation: all (or almost) the adults in Constanza are cachinnans and all the 1xcy are michahellis???? What are the features for michahellis? According to Svensson is this coast a spot for cachinnans for only few Yellow-legged Gulls. I am puzzled.

michahellis has a large breeding population in the town of constanta, thus the multiple juveniles/1cy. it is very unlikely that among the adults you mostly saw cachinnans (which breed 20 km to the north in large numbers). note iris and leg colour, bill shape, primary pattern...
