I watched a documentary this week about intelligent birds.
Scientists did tests with mirrors.
To recognize yourself in a mirror requires self awareness.
Many animals and also small human beings don't realize they perceive themselves in the mirror.
But some Great Apes can.
Some birds can too. Parrots and the family of ravens.
Magpies were shown a treat in a transparent pipe, with a small pit. A thin stick was placed beside the pipe.
The magpie picked up the stick with the beak and pulled the treat out.
But when the treat was placed behind the pit, and when the magpie tried to pull it out with the stick, the treat fell into the pit!
So, next attempt:
Same scenario. Same bird.
The magpie now balanced the treat ON the stick ACROSS the pit!!
So, that allows the conclusion they think ahead= plan, and have intentions.
Which requires thoughts.
We also know this:
Some magpies, not all, recognize themselves in the mirror.
If a yellow dot is put on their chest without them noticing, and they suddenly see themselves in the mirror, they stop and try to get rid of it at once and check in the mirror if it is gone.
So, intelligent animals have a sense of self, they know they "are".
This is highly fascinating.
We also know that many animals have complex sound systems they produce to communicate with one another.
Dolphins and whales "sing", birds sing, and if you're a lot out in the nature, you'll notice that they are communicating with each other, because you pick up WHEN they use them.
Blackbirds use a very special chirp before a rain will come.
All song subsides shortly before the rain begins, and the birds strive to protected places using only this chirp.
Hunters will imitate the calls of a female to lure a male out of the forest.
And then they showed a grey parrot, who was not just talking nonsense, no, he used words for the right things, and he made sense.-
Shown carrots, he was asked: "What is this"?
Asked how many items were displayed on a hand, he gave correct answers. This proves a parrot can count!
I'm not surprised, to be honest with you.
So, yes, animals communicate, in their own sound system, but less complex than we do, and what they say, we are too ignorant to grasp, just as we can't understand a word of Kongolese if we haven't studied it.
I hope that answered your question a bit?
