No sign of the Ring-necked Duck this morning sadly. The Barnacle Goose below was with a v large flock of Canadas that arrived this morning. Also present 3 Shoveler [2f 1m] and 2 pairs of Gadwall as per the other day and 1 AdW Med Gull on E lake. Also checked CBWR, R. Taff at Hamadryad and Prospect Place for R-n Duck but no joy.

Very nice still John. Great light.
This bird has now been seen out of the water and has no rings or the like, so looks a pretty good candidate for a wild one.
Gen inasmuch as it’s could be feral. Highly improbable it’s a wild breeder from more northerly lands.
You’re probably right Barry. More like wishful thinking on my part.
