Hirundines - Crundale and St Davids

Following a couple of Sand Martins over Crundale yesterday, we had Sand Martins and House Martins in a mixed flock of about 60, plus c6 Swallows, over the irrigation pond to the NE of St Davids at GR SM 772 287 today. There were several Canada Geese and a couple of male Tufted Duck too.
