Blue heron is a wading bird - a bird with long legs, sharp mouth and tall head. When it comes to wading birds, we usually think of cranes, storks and egrets - beautiful species, but in the real world, this kind of bird is much more ferocious than we think. Among them, the more famous one is the blue heron.
Blue herons are divided into big blue herons and small blue herons. The big blue heron is a large bird of the heron family of the stork order. Most of the body's feathers are gray blue, and there are filiform feathers on the chest and back. The crown feather formed by two long black feathers hangs behind the head like a braid.
