I like the heading of this thread: 'natural' does entrance, which is 
why we spend so much time observing and discussing it!

  Much has been written about how bees remember things, but how do they 
forget?  A swarm, natural or artificial, can home itself or be hived 
close to its old home but they don't all fly back to it, although it 
must be fixed in their memory.

As for doing all the clever things they do while each having only a 
tiny brain, remember that they aren't just individuals but form part of 
a 'superorganism'  and so, just as they share food and warmth and work 
such as cell building, maybe they also share brain power.  The communal 
brain cells of a colony of bees must be as large as the brains of some 
mammals.
