This series shows the amazing skill, speed, and agility of this Tricolored. And patience, the initial photograph is a bird frozen in time, waiting for the perfect moment.
In a fraction of a second, when the time is right, the bird strikes.
During the strike the Heron must adjust as the prey moves and the image changes with the refraction in the water. Above you can see the twist of his neck.
Here the fish has been caught and quickly pulled up.
I think this was a small fish that was caught. Herons are not fussy eaters, so it could be almost anything.
