I owe Mr. Smith an answer to a question that he asked in October. What would Lucy eat in the wild, I think he meant.

According to this expert she would eat nuts, fruits, berries, leaf buds, and blossoms when available. He says they don't often feed at ground level, unless their population has lived on the edge of a village for some time.

I've read in other sources that the reason African Greys are so smart is that they ARE ground-feeders and need to keep their wits at all times.
