You've seen how animals act, if you get them right after a change, before they come all the way back to being themselves?
This may not be true as some animals act in a way to secure their future needs.
It is there to coordinate movement, to process the input of the senses, and to make the animals act a certain way.
The birds, animals, and plants here acted as if they had never seen a human before.
It's always difficult to know quite why animals act as they do, especially when it is not often observed behaviour.
An animal also acts in a certain way; this is its behaviour.
Your presence changes the -animals' behavior, so the further back you keep, the more natural the animal will act.
But all other animals act according to these same drives, too often with greater enthusiasm and success than man.
Maybe it's the funny way the animals are acting.
"I ask because animals sometimes act like this out of jealousy or disapproval."
