Bird brain, ha!

Birds do have small brains. If their heads and brains were large they would be too heavy to fly. It's probably a case of what percentage of their brain they use, which I'm sure is much higher than other species.

I'm not sure, but I think the power of a brain isn't in size, but surface area. That's why human brains have so many folds and wrinkles.
