A very interesting walk round Two Tree Island this morning. The intention was to hear/see a cuckoo, but that didn't happen. There were a few avocets and assorted ducks at the scrape, and lots of whitethroats. We heard three or four Cetti's warblers, and saw one of them fleetingly, but the pièce de résistance was an adder, wriggling across the path in front of us. It's years since I have seen one. This was quite a small one and in perfect condition. I don't think it was more than about 15 inches long. Fortunately the dog didn't see it.
