Dave Hamilton referred to my online paper at:

and asked:

" Quite a few experiments have tagged the attendants from the dance and
watched them arrive at the food.  Why would this not demonstrate
communication?

What about the mechanical bee .. it was able to recruit "


Julian O'Dea: The tagging experiments could be explained
by odour communication. The mechanical bee experiments
have been criticised statistically in the following
paper:

search behavior, and flight ranges of honey bees. Am. Zool.
