That's a good picture, and it serves to make this point - that the birds look totally devoid of intelligence. Their vacuous staring eyes are quite repulsive.  They starkly show that the birds haven't a clue about what's going on. They're just reacting instinctively.

Heck, look at the bird on the right - it's got blue and silver metal rings attached to its legs! .And it can't peck them off, because it doesn't know how to use technology.  

The rings were put on by humans, who do understand technology. Which is a product of human intelligence.  And the more I contemplate this picture, the more I appreciate the value of human intelligence.

For example - about the eggs. The birds don't know what the eggs are. I mean,  suppose the eggs were replaced by ovoidal lumps of plastic. Slipped into the nest while the birds were away.  Wouldn't the birds continue to sit on the plastic eggs?

Whereas, that wouldn't happen in a human situation. If a human woman, had her baby substituted by a plastic doll - the woman wouldn't be fooled for more than 3 seconds. She'd realise the imposture.

That's why our human intelligence is the greatest, most valuable and precious asset on the planet.  Who cares about stupid birds?

They're yesterday's forms of life.  The future belongs to humans!
