A Black redstart was reported from Cardiff Bay barrage so off I stomped to try to find it. Despite much searching, scanning with my bins, and walking back and forth, I failed to find it (I was somewhat gratified to learn later that more experienced birders had also not found it). But there was a small bonus, in the form of this delightful Stonechat.
It was very active, flitting frequently between shrubs and rocks and back again, quarrelling with one of the resident Rock pipits, and being told off by a stroppy Robin. Luckily for me, in the middle of this flurry of activity it came to rest quite close to where I was standing and I managed to get a few nice photos. It was very entertaining!
