I was fortunate to come across this Heron fishing in a backwater area of a lake but it took some time to capture this photo with the Heron flipping the fish up in order to turn it, so it would go down it's throat head first. Camera was a Canon 5D Mk III with the Canon 500mm f4 lens on a tripod. Settings for this photo as follows. Aperture was 5.6, speed was 1/1600 sec and ISO was at 400.
