alt Hacker NewsGiven the tiny size of avian brains compare to mammals, particulary humans, it's hard to ascribe a lot of intelligence to them. But for what they can do, they seem quite well optimized.

Bird brains are wired differently, neuron density is higher... so using size to compare brains is not enough.

And that’s why Elephants are generally considered more intelligent than humans!
Brain size is not a decisive factor in estimating intelligence and corvid brains pack twice the neurons per volume compared to humans. The factor is: effective "Information Processing Capacity" (IPC), which is high for body size and rivals great apes on specific executive tasks.
Extreme miniaturization eliminates travel distance, giving near-zero latency and high metabolic efficiency despite 1/5th the neurons of a chimp.
