"A Sand County Almanac" by Aldo Leopold, written in Wisconsin in the 1940s. It is a collection of essays that were in draft form when Mr. Leopold died in 1948. His son Luna edited them for publication in 1949. I love the writing! Besides being a naturalist, he was also a historian and the pages are filled with both.
Here is a paragraph: "March. The Geese Return. A cardinal, whistling spring to a thaw but later finding himself mistaken, can retrieve his error by resuming his winter silence. A chipmunk, emerging for a sunbath but finding a blizzard, has only to go back to bed. But a migrating goose, staking two hundred miles of black night on the chance of finding a hole in the lake, has no easy chance for retreat. His arrival carries the conviction of a prophet who has burned his bridges."
Great stuff in this little book which I have only begun to read!
