I done a bit of a sea-watch on the Severn from my home yesterday, raising my bins I picked up what looked like a small tern flying west, it was quite dark the wings appeared greyish , and flying with it’s wings folded back in the manner of a Swallow, unfortunately I did not get it in my scope, and then I lost it behind some trees. I picked it up again flying away from me and then it was gone, As it was morning the light was coming at me. I am wondering if it could have been a Black tern? but will have to just dismiss it as one that got away. To cap all I later I had what was certainly three comic terns flying n/w but picked them up to late to be certain. there was a Scoter though which was probably two. Oh well
