A few records from Sarah Loving, staying at St Davids:
28th April - 4th May, Dowrog - Cuckoo calling nearly continuously (including at night)
29th April, over Treleddyd-Fawr at SM753280 approx - at least 7 Swifts
1st
May, near Carn Llidi, SM740285 approx - 11 Choughs, which may be normal
but seemed like a large group to me; and another Cuckoo calling
north-west of Carn Llidi, SM734283 approx.
3rd May, Aber-pwll, near Abereiddy - a Common Sandpiper
