For some reason many people become obsessed by these wonderful little birds. I know one chap for instance who spent nearly 2 months staked out in a local bird hide photographing them and waiting for the day their young would fledge. He very nearly missed it too but we both managed a few shots. I too am guilty of spending an inordinate amount of time trying to get that magic shot of a Kingfisher just as it exits the water with a fish. I have come close but have yet to succeed.
