Mainland Manx Shearwaters?

While staying at a campsite at Cwmtydu, i noticed a manx shearwater flying out to sea from the small valley at  Cwmtydu beach on wednesday 10th 21.00 hours, then i heard them again from our caravan in the early hours of thursday 11th calling..maybe this is an inland breeding site ?

An intriguing record.  Manx Shearwaters have been suspected of breeding on the mainland in Ceredigion and have been heard at several places along the coast and even inland, including at Cwmtydu.
