In September's episode, we track the slow drift into autumn. Hearing a tale of Ganesh and the moon, we explore the names for September's full moon. We visit the border between France and Switzerland for a very special cheese, follow the migrations of Nathusius' pipistrelle bats, and encounter the spirit of the corn.
