A third sound that I associate with fall is not made by nature, although it does require a natural object to produce it. This is the sound of the shofar or ram's horn, that Jews blow on Rosh Hashanah, the Jewish New Year, as well as during the Hebrew month of Elul that preceeds the holy day. The Jewish calendar is lunar, so the exact date of Rosh Hashanah varies form year to year, but it is usually in September. (This year it is quite late, beginning after sundown on the 28th.)

I suppose that in the Southern Hemisphere, where it is now the beginning of spring, not fall, there are other nature sounds that Jews associate with Rosh Hashanah. But for me, it is the sound of the crickets and the calls of migrating birds that remind me the High Holy Days are coming.
