Green herons are rather small compared to most other herons, but that doesn't make them any less cool. They pack a lot of attitude and cool behaviors in their stocky little bodies. Generally green herons are pretty solitary and keep to themselves, but during breeding season that all changes. They become very vocal and territorial. Its a common sight to see 3 or 4 green herons chasing each other around the marsh.
These herons are one of my favorite looking birds found in a wetland. From a distance they don't look like anything special but when you get up close you start to see all the neat patterns in the feathers, from the layers of different colored feathers on their back to the long stripped neck. Add that their ability to puff all their feathers up to give them a bit of a spiked hair look, and the colors they get on their legs and face during breeding and you have a cool little bird.
They also get bonus points in my book for being on of few birds that use tools and bait to catch fish.
