Cypselus apus
A summer visitor ; local ; numerous in places.
To be seen about the old castles, such as Kilgerran and Pembroke, about the cathedral at St. David's, &c, &c. Also evidently nesting in places in the cliffs on the coasts, in crags inland, in old cottage and farm-house roofs and chimneys, &c, &c. We always had plenty of Swifts about us at Stone Hall, and imagined that many bred in some rocks by the banks of the Cleddy. They generally arrived with us on 4th May, and left us again in the first week of August, but we have seen one as late as 30th September.
