    I’d argue that the brain volume alone is not nearly as important as how it’s wired. There are lots of animals with high brain volumes that aren’t terribly intelligent. While there is evolutionary pressure to optimize energy use, there is also a competing pressure to make the system more robust. Having redundancy means that the brain can survive more severe trauma creating an evolutionary advantage. Meanwhile, birds have a stronger selection for optimization since they have to be able to fly and hence why I think we see more efficient brain architecture emerge.

      Yes, whales have a bigger brain, but not in relation to their boddy mass. They are also animals with considerable intelligence, although not as much as those of the Delfinoid family, such as Dolphins and Orcas, whose brains in relation to their body mass is much higher and also much more complex.
