The morning was windless with a hint of pale sunshine that almost reconciled me to no longer being in sunny Valencia, so I headed off to Leighton Moss. It was a delightful day: the marsh harrier was having fun dive-bombing the ducks on the pool and giving them a lesson in how to fly effortlessly. Siskins and goldfinches were twittering joyfully as they raided the alder trees. Shovelers, pintails and teal were on the pool, and I discovered that the great-crested grebe doesn’t have a crest in winter. There was also a family of crows making the most of the duck carcasses at the edge. And a robin popped up in a seasonal appearance.
