I had a 10 minute stop at Fendrod on the way home today, but no Casp-types. An adult Med was the only thing of any note, which is surprisingly uncommon there judging by Alastair’s 13 records. There is clearly a steady turnover of gulls, so well worth dropping in for a scan if you’re that way inclined!
