Some more photos form my trip to Kefalonia now, with the black winged stilt I saw on Katelios beach. I wandered down the beach hoping for a glimpse of the animal I had heard dive into the reeds or anything else around when I spotted a bird walking along the dead sea grass. I could see it was a wader and it looked a bit stilt like but it was on its own and the beach had a few people walking along it, so dismissed the possibility. So I was quite surprised when I got closer and it turned out to actually be a black winged stilt Himantopus himantopus!
500 shots later, as I left it on the beach, I decided it was all in all a rather excellent wildlife encounter!
