'Each year a family of stoats raise young along the rocky edge of the Conwy estuary, in north Wales. This is part of the RSPB reserve and, the young animals quickly become accustomed to people walking nearby along the estuary path. I was fortunate enough to see them on several occasions, and on this instance was lucky enough to see these two juveniles play fighting amongst the rocks and seaweed for the best part of an hour. Before seeing this family, my stoat sightings had largely consisted of fleeting glimpses of animals sprinting along field edges. Seeing these animals and being able to observe them growing and developing in such a different habitat has given me a whole new insight into the species'
