[Oberon] Active Cells

[Douglas G. Danforth]

Evidence that birds can form abstract concepts such as /same v. 
different/ has been provided by Alex 
<http://en.wikipedia.org/wiki/Alex_%28parrot%29>, the African Grey 
Parrot <http://en.wikipedia.org/wiki/African_Grey_Parrot>. Alex was 
trained by animal psychologist Irene Pepperberg 
<http://en.wikipedia.org/wiki/Irene_Pepperberg> to vocally label more 
than 100 objects of different colors and shapes and which are made from 
different materials. Alex could also request or refuse these objects ('I 
want X') and quantify numbers of them.^[26]

Macaws have been demonstrated to comprehend the concept of "left" and 
"right." ^[27]

I believe some birds exceed the capabilities of humans with regard to 
counting.  Twelve is the
number I remember for some birds.
