Images of adult Yellow-legged Gulls Larus michahellis, taken in the first week of December 2014 in the Algarve, Portugal.
Female, seen with partner (Bird #2) in the harbour of Quarteira, 4 December 2014. Note the orange eye ring and the limited black on P5.
Male, seen (in fading light) with partner (Bird #1) in the harbour of Quarteira, 4 December 2014.
This individual seemed to have a damaged right eye. The large amount of black in the bill seems to point to a young adult, but no other immature features can be seen in the plumage.
Also note the black mark on the outer web of P4.
