Yesterday evening Chris Bird counted at least 50 Pied Wagtails going to roost in bushes at the Parc y Llyn retail park. Urban winter roosts are well known but we both thought this was an odd time of year for such a gathering.
I delved into the records and found that the late Hywel Roderick had a pre- roost gathering of 350 Pied Wags on Blaendolau playing fields ( very close to Parc y Llyn) on 4th April 2003. Perhaps not that unusual then and well worth keeping an eye open for.
