Walnuts, brain size and you

Combining some recent news, some really old news, and your place in between. Or not.

The recent news: Birds might have tiny brains, but they still may be very intelligent (as animals go). Now, on a related note, discoveries show that the brain cells of birds may be smaller and/or much denser packed than they are in, e.g., humans and family.
The really before-stone-age news:

Combined: Birds have a separate line of descendance from their dinosaur-time quite-close equivalents. Having survived some dino extinction rounds and still remain quite similar in body and operations as before, having kept the same lightweight and small-package brain structure too?
Then, maybe the dinosaurs weren’t so stupid either with their small but possibly also very densely packed neurons and they just had a bad hair day (that’s what you get when a comet strikes your coiffure — footballers beware).
Just a, very,very,very after-the-facts hypothesis… And:
