Guided walk at Wheldrake Ings, hampered by ice, fog and rain. Half the folk didn't turn up, but the brave dozen followed me round the hides. The fog lifted a bit at the far end so everybody managed views of Whooper Swans down my scope. On the way back, I heard the trilling of a Waxwing and looked up to see one heading over west. Bonus. On the drive back through Wheldrake, three birds were sitting in a roadside tree as I entered the village.
