In May 1834 Charles Waterton had himself lowered by rope down the cliffs at Flamborough by two local egg-gatherers:
‘The sea was roaring at the base of this stupendous wall of rocks; thousands and tens of thousands of wild fowl were in an instant on the wing: the kittiwakes and jackdaws rose in circling flight; while most of the guillemots, razorbills, and puffins, left the ledges of the rocks, in a straight and downward line, with a peculiarly quick motion of the pinions, till they plunged into the ocean.’
Charles Waterton, ‘Essays on Natural History’ (1835-1857)
My version of this scene was based on this Victorian engraving, artist uncredited except for the initials in the bottom left hand corner, which could be those of the engraver.
