At the moment in Norfolk, we have big flocks of pink-footed geese on the fields at the back of the house, where the sugar beet has been harvested. This temporarily leaves plant debris on the soil, which the geese love, and the farmers don't mind, as they have got their beet in.
It's wonderful to watch them arrive, circling down in big skeins, making their rather wild shriek as they do so, and then another skein arrives. They say that on a moonlit night, they will stay to feed, but on dark nights, they fly back to the saltmarsh to roost. I'm not sure how many there are, but around 200, 000, I think, so we get a few thousand fly onto the fields locally.
We also went down to see the wild swans at Welney, mostly whooper swans from Iceland, but also some Bewick's from arctic Russia. Just a touch of wildness for us, and an amazing spectacle at the moment, with massive floods right down the river Ouse, but safely contained by the banks which have been built.
