Thick fog hampered visible migration watches this morning but a brief respite early on saw a Corn Bunting, two Bramblings and a Fieldfare among a few birds on the move at Reighton Sands. Later in the day, a firecrest was trapped and ringed in the Top Scrub, while two Shelduck, a male Pochard, five Chiffchaffs and 18 Tufted Ducks remained at the Dams. A total of at least four pairs of Lesser Black-backed Gulls are breeding in the town this year the highest number recorded.
