Out along the causeway, Dave Lowe kindly put me onto some adult Little Gulls on F1 - but too distant for photos. On F2, there were c. 12 Common Terns but initially no sign of any Arctics or Black Terns.
Over the causeway and down to the meadows and river beyond, there was a vocal Cuckoo flying around from time to time.

Further on at the pool with the footbridge at Buckthorn Meadow there was a Sedge Warbler that was coming up into the tops of the reeds from time to time.
