While going through a couple of hundred gulls sheltering in the Teifi Estuary for my WeBS count, a Sand Martin flying over was a nice surprise. A second, or the same bird, was over the river viewpoint on the Teifi Marsh.
Other birds of note were a Red-breasted Merganser and Great Crested Grebe near the boat builders. Wigeon and Teal numbers were down and Shelduck up as usual for the March count. 3 Goldeneye and 3 Goosander on the river.
