There were splashes of other colours too, notably the larch blooms

Plus the birds were all singing, despite the rain. I stopped to listen to two song thrushes singing, one on each side of the river, answering each other. I first heard them when I walked upstream and they were still singing when I came back downstream on the other side of the river, over an hour later!
