A couple of hours on the boardwalk first produced 4 singing Willow Warblers and near them, a couple of noisy Willow Tits. I digi-scoped one of them while it was briefly on a post some way from us.
Jill and I then had a noisy Green Sandpiper fly up from nearby. Near the Bog Hide we heard another Willow Tit.
As soon as we were in the hide a juv. Marsh Harrier passed by, but without allowing us to get the details on a wing-tag.
