Black heron is a shady fisherman

The black heron has evolved its own very special fishing technique. It casts an umbrella-like shadow over the water by spreading its wings. It is thought that this serves a dual purpose: It helps to shade the heron's eyes from the glare of the sun and the shady spot that is created under the water attracts fish.
