Up in Scotland for a family celebration, we headed out one morning for a walk, following a night of heavy rains. The dampness was still thick in the air as we descended down towards Loch Awe in Argyll, western Scotland. A flicker of movement caught my eye in the low vegetation by the side of the path. Peering closer, a pair of eyes looked back at me, the rest of the body hidden beneath random detritus, dampened by the storm the night before. It was a small frog, taking refuge from the elements.
