Blue heron - a magical bird that only needs to shrink its neck to turn into... 2 different species

They are usually quite large with an average height of 1.3 meters, a length of about 1.3 meters from head to tail and a wingspan of more than 2 meters.

Although the heron's diet is mainly fish, it has also been found to eat shrimp, crabs, insects, mice and other small mammals. Blue herons also eat amphibians such as frogs, snakes, reptiles and even crocodiles and baby sharks.

Blue herons are usually quite large with an average height of 1.3 meters.

However, what makes blue herons so impressive to people is their neck.

As seen, blue herons can deceive people by pulling their necks short or long.

Such before and after pictures can make people immediately think that this bird is very interested in drama, every "turn" is to pull its neck out to the fullest to hear it clearly and wait for the full story.

.but I've been waiting for it to stop.

However, this is only a biological mechanism of the blue heron. The act of pulling the neck is merely to swallow the prey more easily.

The digestive mechanism of the blue heron is very special. They have very large beaks, flexible esophagus and stomach that allow blue herons to swallow large prey. That's why a blue heron here can eat a whole baby crocodile, swallowing it from head to tail.
