Today the birds were very nerved and it was difficult to take good pictures but i got a few!
A difficult gull (a) looks as CG but with lot of black underwing... in front of a Heuglin's:
Gulls on the island of Crete, Greece. Several species winter, seen during migration and two species breed. The ID problem in some individuals made me to create this blog but I will also put pictures of "known" ones and more informations about their behaviour, distribution and general status.
