Each of the big wading birds has their own style and method of fishing. The Tricolored Heron is nothing short of a show.
It works too.
One of the first things they do is dance, shuffle their feet and walk.
Wings are spread next, and the pace steps up.
The wing movement depends on the sun. What they are doing is using the shade made by their out stretched wings to make a shadow on the water. They can see small fish better.
This is really fun when you have a group of Tricoloreds.
It’s like a chorus line.
