I have received this email from Jon Green to be posted re Starlings – thanks Jon for the info
As regarding the Starling flocks in south Ceredigion. They come from north Pembrokeshire, over Cardigan and on towards Rhydlewis - if not past that - at a guess to Plwmp.
In winters past birds used a roost around Mwnt / Felinwynt but that seems to have gone by the board now. The roost on the Teifi marshes may still be around but I expect that they too go north.
As for how far north they are coming from, I'm not sure but I would be very surprised if they were the Aberystwyth birds.
