Yellow-legged Gull (Posterior caerulus lusitanicus)
António A Gonçalves recently uploaded some lovely gull shots from Cascais, just outside Lisbon. This remided me of a brief work trip to Lisbon when I got a few hours to get out there to look at gulls. As it was September I was interested in the moult patterns of the local Yellow-legged Gulls which were flying below the cliff top. I was so engrossed in this that I didn't notice the couple in swimwear until I put photos on to my PC at home. Honestly Officer!
