In the world where you can see every type of crane from every part of the world.

The cranes you see in that photo started getting excited and flapping their wings because someone was approaching their cage. Some of them are a bit more tame, but others really do not like people and will try to scare you away if you get close to their cage. Some will flap their wings and run at incredibly fast speeds towards the fence if they see you coming closer.

and what’s funny is sometimes if they get stressed out (okay their stress isn’t funny, but what they do is.) they will face each other and make strange motions. They use a lot of body language to communicate.
