Dropped in at Marloes by chance (phone-off!) briefest of views of a cracking bird as it pottered around at waters edge picking up flies/pupae drifting in by the wind. There was a moorhen in same area which seemed to unsettle the Black-head and Pieds that were feeding there.
As Trevor mentioned the Glossy flew through our field of view while scanning for the wagtail from the barb-wire gate and settled out in the open.
Gann: Merganser out in bay along with 7 Mute swans, Bar-tailed godwit and 6 distant terns (Sandwich?). Kete/St Ann: 4 Wheatear in the last field before lighthouse, 2 swifts and a chough.
