A very short visit to Llyn Coed-y-Dinas at midday today, but a new experience for me. At migration time, I tell schoolchildren that the reserve is similar to a Motorway Service Area, and so it proved today. A single species flock - (no Sand Martins or Swallows) - of House Martins, numbering between 80-100, arrived, drank, and moved on within 2 minutes. I could so easily have missed it.
