Cetti's heard at WTSWW Llangoffen Ffen nature reserve yesterday (23/10/20) and the day before on Goodwick Moor by Fran Eggby.
At least one pair of Cetti's (probably) bred on both the Llangoffen nature reserves, perhaps more as males heard throughout the breeding season at different locations.
Nice to see or at least hear them as many younger birders may not realise they are are relatively recent additions to our county avifauna, see: https//pembsavifauna.co.uk/2020/03/02/cettis-warbler
