Why are birds so smart?

Why are birds so smart?

All animals are retarded.

Depends entirely on the birb in question but cleverness is usually a good replacement for brute strength(see hominids), and birds are pretty delicate with their hollow bones.

They're familiars of a higher intelligence master being.

Natural Selection

Birds have brains that have dense neuron connectivity.

In other words you know how they say humans only use 10% of their brain, birds are using 80% of it.

>humans only use 10% of their brain
This theory is completely blown the fuck out for over a decade now.

Depends on from which perspective, but it's a spectrum

Why natural selection did birds smart instead all other species?

So, a birdman would be a genius?
