Quote: Parrrot and songbird brains, for example, contain about twice as many neurons as primate brains of the same mass and two to four times as many neurons as equivalent rodent brains.

Birds have more densely packed neurons in the front part of the brain that are associated with intelligence than mammals whose brains are comparatively sized.

Quote:Among the questions that this study raises are whether the surprisingly large number of neurons in bird brains comes at a correspondingly large energetic cost, and whether the small neurons in bird brains are a response to selection for small body size due to flight, or possibly the ancestral way of adding neurons to the brain - from which mammals, not birds, may have diverged.

If this was purely an avian development after they diverged from dinosaurs, then it probably won't contribute to or enhance the chances of a bipedal dinosaur species having eventually evolved intelligence if they had avoided extinction.

Speculations of anthropomorphic sapient dinosaurs

That makes sense. There has even been speculation that dinosaurs were relatively smart like birds. Was it Moe of the Three Stooges who often cast the epithet "bird brain"? Parrots probably were more offended than Larry or Curly.
