I've seen fleeting glimpses of kingfishers but the only time I've managed to focus on one for any length of time was on a local run when I wasn't expecting see one. Between Romsley and Walton Hill there is a small stream which I cross frequently. I spotted the unmistakable blue out of the corner of my eye and sat and watched in wonder for a few minutes until it realised I was there and flew off. Never seen it since but a special sighting I've never forgotten.
