What about crows and ravens?

• mkl 4y ago
  From [1], ravens have ~2.171×10^9 neurons, roughly similar to dogs, raccoons, some monkeys, some parrots and birds of prey, an order of magnitude less than chimpanzees, which is a third of humans, which is a third of elephants. Whales aren't in this list, but they'd be more again (bigger body = more neurons needed to keep it functioning).

    Without referring to numbers, since I don’t remember them off the top of my head, I believe whales, generally speaking, have less neuron density (but usually higher absolute counts of neurons) than we do but actually have higher folding (gyrification) than human brains. Additionally, in whales, the relative size of the portion associated with emotional intelligence is much higher than that in humans.
