The Natural History of Selborne, both volumes (1790)

Natural history of a town in England, first published in 1790. According to Wikipedia: "Gilbert White FRS (18 July 1720 26 June 1793) was a pioneering English naturalist and ornithologist… White is best known for his The Natural History and Antiquities of Selborne (1789). This was a compilation of his letters to Thomas Pennant, the leading British zoologist of the day, and the Hon. Daines Barrington, an English barrister and another Fellow of the Royal Society. These letters contained White's discoveries about local birds, animals and plants. He believed in distinguishing birds by observation rather than by collecting specimens, and was thus one of the first people to separate the similar-looking Common Chiffchaff, Willow Warbler and Wood Warbler by means of their song. White is regarded by many as England's first ecologist and one of the founders of modern respect for nature."
