1.The Natural History of Selborne
Gilbert White, 1789
Also wonder and nature. A country clergyman spends forty years watching the birds, worms, echoes and weather of one Hampshire parish, and writes it all down in letters of disarming charm.
If ever I saw anything like actual migration, it was last Michaelmas-day. I was travelling, and out early in the morning: at first there was a vast fog; but, by the time that I was got seven or eight miles from home towards the coast, the sun broke out into a delicate warm day. We were then on a large heath or common, and I could discern, as the mist began to break away, great numbers of swallows (hirundines rusticae) clustering on the stinted shrubs and bushes, as if they had roosted there all night. As soon as the air became clear and pleasant they all were on the wing at once; and, by a placid and easy flight, proceeded on southward towards the sea: after this I did not see any more flocks, only now and then a straggler.
