Field notes from the week the light turned

The clocks have not gone back yet, but the light has already changed its mind. Here is a week of it, taken from the usual short walk between the car park and the canal, notebook in a coat pocket, nothing rare, nothing that would make a county record. Only the ordinary business of a place deciding it is autumn.

Monday. The swifts have been gone for weeks, but I still look up at the gap over the chip shop where they used to scream round in the evening. The sky there is just sky now. You keep the habit longer than the birds keep the appointment.

Tuesday. A buddleia growing out of a crack three feet up a brick wall, well past flowering, every spike gone to brown seed, and a single late red admiral working it anyway as if nobody had told it the season was over. It let me stand a foot away. Cold slows them into tameness.

Wednesday. The drain that runs behind the retail units has turned into a proper little stream again after the rain, and something has noticed: a grey wagtail, which is the bright yellow one despite the name, walking the concrete edge and bobbing as if it were a mountain beck and not a gap behind a tyre fitter.

Thursday. Leaves down overnight on the one lime tree the council left, and the smell of them going over, which is a smell I have never found the right word for. Sweet is wrong. Mushroom is wrong. It is the smell of a year composting itself and getting on with it.

Friday. Fieldfares, I think, high and going over in a loose rattle, the first of the winter thrushes coming in from the cold places to spend the dark months eating our hedges. They arrive as others leave. The car park does not know it is a migration stopover, but it is.

Saturday. Spiders. Every railing strung overnight, every web hung with the particular heavy dew of the first cold mornings, and for about forty minutes after sunrise the whole fence is jewellery. By nine it has burned off and it is a fence again.

Sunday. Nothing. A grey morning, the canal flat and brown, not one thing worth writing down. I wrote that down. A week of noticing teaches you that the empty days are part of the count too, and that a place you have decided to pay attention to will never be completely silent, even when it is telling you only that it is tired and wants the winter.

None of this is wilderness. That is rather the point. The wildlife round here never got the memo about wild places, and quietly made do with the drain, the wall and the one tree that survived the car park. It does not need a nature reserve to do what it does. It needs somebody to keep the notebook.

If your walk runs beside a canal, Every Drain Remembers a Stream follows city water from the drain to the sea, and the otters, eels and salmon finding their way back to it.
