The title doesn't make sense because "bridbrain" doesn't imply slow decision making.

Birdbrain should mean the opposite of what it does, for this reason, but for many others. Birds can sense the Earth's magnetic field and use it for navigation, a process that's about the one bona fide quantum biological paradigm.

Their body clocks are also significantly more sophisticated and decentralized than ours.

And in the end, the physical intelligence of flight itself demands a brain that's gotta be incredibly spatially and temporally aware.

I wish our brains had some of the skills and efficiencies of birds.

It's faster probably because their neural network is less deep :)
