I was walking by the lake when a moorhen rushed by with a long bit of reed, I watched as he speed away, I thought it had gone down over the bank but no it started climbing a tree, along a branch and at the very end he handed it over to Mrs who was waiting on the nest. I sat and watched him rushing around collecting and delivering nest materials.
