Well I wasn't wrong. I park by the environment agency and walk down the road with white throat singing just out of view. Then as I approached the lookout on the right a couple of terns flew past. Now I'll go out on a limb (after Ben, Duncan and Mark highlighted this) and suggest Artic because they were making a right racket, but they whizzed past and I couldn't tell for sure.
Anyway it was a miserable morning with clouds and a little light rain. Our trip to Italy wasn't going to be a pleasant one so I decided to just enjoy the sights and the sounds; enjoy the simple things and just reflect on the wonders around me.
