It is the winds from the east, and the north east, which bring winter where I live. Blowing in from Siberia and the Arctic, these winds also bring migrating swans. Bewick swans spend the summer on the Russian tundra, where they raise their young. They migrate to the UK for the winter, flying at night, using the stars for guidance. Young swans make their first journey with parents so as to learn how to do it.

For about three years, I lived in Slimbridge, and then on the canal in the vicinity of Slimbridge – the location of the first Wildlife and Wetland Trust site whose link I shared above. This site was established as a reserve by Peter Scott (son of Scott of the Antarctic) because of the migrating swans. They come to feed on the banks of the Severn during the winter.
While I was living in the village, an older neighbour told me how, when he was a child, the swans would come in incredible numbers and you’d see them flying round the church spire. Swan numbers, like pretty much everything else in the natural world, have been dwindling. It’s now rare to see a migrating swan coming in on a wind from the east early in the morning. It’s happened to me a few times now, and it’s an experience I feel deeply grateful for.
The coming of these winds marks a turn towards colder weather. When it happens varies – the first swan this year showed up in October. Most are coming in now. The colder the weather, the more swans come to Slimbridge – there are other sites migrating swans go to, but the harsher the winter, the further south they head.
Even though I no longer live in Slimbridge and no longer see the bewicks grazing in the fields, they are very much on my mind when the winds come. And this year, I’ve seen several pairs of swans coming in over the hills in the early morning, no doubt heading towards the river.
