I don't keep count of such things but it seems to me that the bird I have photographed successfully more than any other is the grey heron. That's probably because it is a big bird, reasonably common, sometimes tolerant of a close approach, and one that I can fill fill the frame with even using my non-specialist lenses. Today's photograph was taken with the "super-zoom" lens of a bridge camera but the bird was close enough to have been snapped with a more modest lens on my everyday camera. For those who are wondering, this strike was successful and the heron quickly swallowed the fish it caught. The small photograph shows the heron's neck distorted by its passage.
