Good point on cropping the last one, I agree it would be an improvement!
The green herons are pretty small. Some are more of a gorgeous emerald green than others...this one actually being blue. Greens are fun to watch because they actually use tools to catch prey. For instance they might go dig up an earthworm...but not to eat it, no. They would throw it in the water as bait for fish! When the fish swarm to eat the worm, the heron goes in for the kill.
I watched this one for an hour or so but he didn't seem too hungry.
