Green Heron’s often do not look green because the green is not a bright, neon green, but rather a dark muted green. Also, from a distance, which is where the bird is usually viewed, the bird looks more brownish or greenish-brown. I was lucky enough to photograph from a fairly close range one of these birds last week. Zooming in on the feathers on its back, here’s why it’s called a Green Heron. Of course, much of it depends on how the light is hitting the plumage.)
Here’s a full view of the bird.
