Incluso o "moi observador" Gilbert White, na súa obra publicada postumamente en 1789 The Natural History of Selborne (A historia natural de Selborne), citaba a historia contada por un home de que as andoriñas foran atopadas no derrubamento dun cantil de greda "cando el era un escolar en Brighthelmstone", aínda que o home negou ser testemuña visual.
