Edmund Selous, The Bird Watcher in the Shetlands…
“ Who shall say that a man, returning to his home at the end of the day, sees in his mind's eye a clearer picture of what awaits him there than does the bird flying to its nest, or the bee to its hive? Now could anything, by association, call up this picture, suddenly, in the bird's or insect's mind, they would, no doubt, act for the moment as though it were real—as did Darwin's dog when he called him after five years' absence; and thus I can understand one of these guillemots flying with a fish to its ledge, to feed its chick, although its chick were no longer there. ”
