A black dome of feathers stands hunched in a marsh in Africa.
Odd as he looks, he’s ignored by the cattle egrets.
When he raises his head you can see he’s a black heron (Egretta ardesiaca).
His cape lures the fish to the darkened water and cuts the glare so he can see below. This behavior is called canopy feeding.
Watch him in action in the tweet below.
