"The most important components of most parrots' diets are seeds, nuts, fruit, buds and other plant material. A few species also eat rats and worms, and the lories and lorikeets are specialised to feed on nectar from flowers, and soft fruits."

Vibram posted three portions of an interview with Harvard professor Dan Lieberman.  I've also posted the profile of Lieberman and his work from when it appeared in Nature.  All short and worth watching.  

And personally, Professor Lieberman is a great guy.  I had the opportunity to hear him speak at the Harvard Club last fall.  Awesome presentation -- can't wait for his book.  He's done all sorts of cool research on how different parts of the human body give us clues as to what types of movements we're adapted to.  Like we have a muscle in our necks to keep our head from bouncing around that running animals tend to have.  He's currently in Kenya, or as he put it to me, "in the land of barefoot runners".
