A conversation I had this weekend reminded me about the efficiency of these predators, and how easily this great blue heron managed to catch small fish in the shallows of Rodeo Lagoon. It seemed like every time it put its head in the water, it came up with a meal.
Here's a frame when the heron was facing straight on. I like how you can still see the pattern of its head through the wall of water its forcing towards me.
And if you'd like to see this bird without a wall of water in the way, I posted a few shots of it earlier this year: "Great blue on blue" and "Heron with attitude".
