As a further comment on Robert Homan’s post of 18 September about the start of autumn, there were Chiffchaff’s singing in my garden this morning (they’ve been quite noisy again for several weeks now)and Redwings flying overhead (the first I’ve seen or heard in Gloucestershire this season). So it has to be the changeover time when there are still the summer migrants present, yet the winter visitors are beginning to arrive.
