A few days at work in Lincs were plagued by fog but interspersed with bright sunshine, and on 19th there were small gulls everywhere at Saxby, following a selection of ploughs. A handful of adult Meds were picked out, and at 2.35pm I looked up to see a gleaming 2cy Iceland Gull soaring overhead! Two hours later, thousands of gulls were streaming north to roost on the Humber, and in a more distant group I picked up a big buffy 2cy Glauc dwarfing the surrounding Black-heads. Both wingers in an afternoon! Next day the Iceland was relocated in another ploughed field with 4 adult Meds in the area, but no Glauc.
