The Black Heron (Egretta ardesiaca), an African waterbird, have a unique and dastardly predation tactic called canopy feeding.
They hunch over and form their wings into a circular makeshift umbrella over the water. This blocks out the sunlight and creates a small area of darkness underneath. In addition to helping the bird see what’s going on in the murk, surrounding fish are lulled into a false sense of security by making them think that either night has fallen or the shady area is a safe refuge. It’s neither. When a gullible fish then proceeds to poke its head out from its hiding place to investigate, it’s curtains by way of a brutal beak stab.
