Okay, but does easy living make birds dumber?

Okay, but does easy living make birds dumber?

E28. A bird's brain is the most expensive thing it owns, and evolution doesn't hand one out for free. Dr. Carlos Botero, Associate Professor at the University of Texas at Austin, has spent a decade tracing what variable, unforgiving environments actually do to bird cognition, and the answer flips a lot of conventional wisdom on its head.

In this episode:

  • Why the harshest places on Earth produce two kinds of birds: the puzzle-solving geniuses and the brute-force survivors, with almost nothing in between
  • How big brains might not have evolved for the reasons we always assumed
  • Why being one of the smartest birds in the sky can come with a hidden cost
